PowerBook and iBook G4 FAN Control

G4FanControl Your Mac is too hot? Excessive heat or to much fan noise? The system freezes? Do you want to control the fan speed? This software solves all your problems! Read the comments!

G4FanControl is an useful Application that can be used to specify a certain minimum temperature limit that much be reached before the fans on a iBook/PowerBook G4 laptop start up.
Default temperature limits will be restored by Mac OS X in the event of a reboot.

From the time I acquired my trusted Powerbook G4 15" it has never given me a problem. However, as anyone who has put their hands on this wonderful laptop can attest, the operating temperatures quickly climb and it soon becomes practically impossible to touch, especially on the bottom under the display. What makes this situation truly absurd is that the PB actually has two powerful FANs, but, for some reason, they have been rendered practically unusable by operating system. In fact, Apple, probably for reasons to do with battery life, has thought it "opportune" to set the minimal activation temperature of the FAN to around to 60° and also "conveniently" denied users the possibility of managing them manually.

I spent some time researching the net for a program to manually manage the fans but nothing was available so I wrote this one. The entire G4 Powerbook and IBook cooling system is managed from the ADT7467 of the Analog Devices. The ADT7467 has 1 integrated temperature sensor (Local Sensor) and 2 more remote sensors, can control the fan and, what's more interesting, is that it manages all of it without any participation of the processor.

The chip it is mounted on a I2C bus. The datasheet illustrates the addresses, subaddress and relative values so you can have a total control over the entire cooling system.

My solution is simple: lower the minimal limit (TMin) temperature setting for every sensor.
In this diagram, the Temperatures variation can be observed before and after the fan was set to the maximum power!

Do you have in English? so I can read..
Thanks

Two items:

One, it would be really nice if you listed which versions of Mac OS X this item works under -- that is, if it's compatible with 10.4, 10.3.9, 10.2, etc.

Two, it would be really nice if there was a way to run the command to show current settings without having to specifiy a setting. That is, to be able to display current settings without changing them.
#4 - David [2007-05-31 08:05:13 CET]

This looks very promissing. Thank you for developing. Is there any chance at a simple gui? Also is there any way of knowing the current temperature? I really look forward to testing the widget. I can't say thank you enough for developing this!! Grazie!!
#5 - Gianni [2007-05-31 16:18:57 CET]

Utility testata e funzionante su iBook G4 800 con Macos 10.4.9, statistiche e prova con alcune impostazioni ok. Può tornare anche utile per 'testare' le ventole nel caso si dubiti del loro corretto funzionamento o per tenere meglio sotto controllo le temperature di "servizio"; in vita mia ho "ascoltato" pochissime volte le ventole al massimo della potenza sul mio iBook, in particolare 'dopo' l'installazione di Tiger il sistema mi risulta piu' silenzioso. Grazie per aver messo a disposizione la tua utility. ;)
#6 - Ergo [2007-05-31 17:13:05 CET]

I, too, would appreciate a GUI; I'm one of those dunderheads who isn't very knowledgeable in using Terminal commands.
For David, above, and others who would like a graphical monitor to see their 'Books internal operating temps, there's the excellent "Temperature Monitor" available here(it's free): http://bresink.com/osx/TemperatureMonitor.html.

#8 - julien [2007-06-01 12:01:32 CET]

It works on my PowerBook G4 Alu 1Ghz (15 inches)
Great app !

For everyone : don't forget to do the command with sudo, I miss that at the first use :P
#9 - Eric [2007-06-01 12:06:06 CET]

Works fine on a PowerBook G4 12" 1,33 Ghz running Mac OSX 10.4.9.
Great !!!!
#10 - fabrizio venerandi [2007-06-01 14:07:15 CET]

molto interessante, tre domande:
a) il ho il problema opposto, vorrei alzare leggermente la soglia a cui partono le ventole perché credo che la apple abbia messo sui pb una soglia molto bassa per il fastidio dell'alluminio all'utente, più che per il reale pericolo per l'elettronica; però vorrei variare un solo paramentro, non tutti e tre. è possibile?
b) è possibile ripristinare i valori iniziali senza la noia di voler riavviare?
c) i programmi di temperatura mi hanno sempre trovato 4 sensori: batteria , cpu, gpu e hd. Il tuo programma trova gpu e cpu e aggiunge un 'local sensor temperature' che non ho mai visto prima e che è proprio quello che fa scattare facilmente la ventola. sai di che si tratti?


ciao e grazie
#11 - clem [2007-06-01 16:33:19 CET]

sul mio ibook 1.33GHz (l'ultimo modello), funziona benissime. Aspettando il stesso miracolo per il mio Quad G5 ... Grazie un sacco !!!!
#12 - Andrea [2007-06-01 21:56:31 CET]


In risposta a Fabrizio Venerandi:

a) Si è possibile. Il controller offre la possibilità di specificare qualsiasi temperatura limite e anche per ogni sensore separatamente.
b) Automaticamente no, poichè il controller in se non ha alcuna impostazione di default, infatti i parametri vengono settati dal driver di Apple al momento del caricamento. Quindi la cosa più veloce sarebbe scaricare il driver e poi ricaricarlo.
c) L' ADT7467 dispone di 3 sensori, 1 onchip e 2 remoti. Quello onchip è integrato nel chip stesso e quindi si trova sicuramente sulla scheda madre, ma non so dove di preciso. Temperature Monitor lo indica come "Controller Bottomside". Poi sullo stesso bus è montato un ulteriore chip, l'LM7x, che si occupa di monitorare i restanti sensori.
#13 - Will [2007-06-01 22:45:48 CET]

Hello !

Thanx for this nice app.
I have juste made an user interface in AppleScript, this could help lazy users =)
The GUI "PBG4_FanCtrl.app" run under MAC OS 10.3 and 10.4, it is bundled in English and French for now.

I post here the temporary link to the GUI, i'll post the source code of this GUI if somebody is interested :

works great! thanx:-) my fans never turned on until now...of course, my battery life's gonna suffer;-}
#15 - fabrizio venerandi [2007-06-01 23:39:05 CET]

grazie per la risposta: non ho però capito se la variazione delle soglie dei singoli sensori è variabile con g4fancontrol. al momento mi pare che io possa variare solo tutti i sensori in blocco (e mi pare che ci sia anche un tetto a 60 gradi).

Per il sensore è strano, sul mio powerbook 12'' temperature monitor mi segnala il battery, il processor topside, il graphics processor die, l'hard disk drive bottomside elo smart disk toshiba . nessun 'controller bottomside'.

grazie

#16 - Incendio [2007-06-02 02:06:44 CET]

Grazie , da me vas bene
Bon di a te
#17 - Andrea [2007-06-02 08:00:36 CET]

In risposta a Fabrizio Venerandi:
No, non è variabile attraverso G4FanControl. Non ho ritenuto apportuno scavalcare le soglie minime impostate da Apple. La disposizione dei sensori varia in base al modello (probabilmente anche per motivi di spazio). Infatti sul mio Pb 15'' è presente quel "controller bottomside" ma non è presente il tuo "gpu".
#18 - fabrizio venerandi [2007-06-02 09:39:33 CET]

beh se posso permettermi di fare una richiesta, avere la possibilità di settare i valori singoli (senza tetti) sarebbe piacevole. anche perché ora posso variare i minimi alzandoli di botto tutti, ma poi non posso riportarli ai loro valori originari senza ribottare (il minimo della gpu è di 92 che è oltre la soglia di valori di SET)

grazie
#19 - fabrizio venerandi [2007-06-02 11:24:47 CET]

aggiungo: questo perché apple (secondo me) ha messo una soglia bassissima al sensore centrale, per i fastidi che il calore dà al tatto o alle gambe quando si scalda, e non perché effettivamente ci sia bisogno di una dissipazione così frequente. per dire, il pb 12'' 1,33 fa partire la ventola a 46 gradi, l'ibook g4 a 1,2mhz la fa partire a 56...
#20 - tomazo [2007-06-02 15:42:49 CET]

Hi, thanks for this , but how do i change back to default?
Andrea: Simply, reboot your system! :)
#21 - Andrea [2007-06-02 19:03:06 CET]

In risposta a Fabrizio Venerandi:
E' probabile che in una versione futura di G4FanControl verranno implementate queste funzionalità, ma per la prossima versione ci sono cose più importanti da affrontare. In primo luogo il supporto per tutti, o almeno per la maggior parte, i modelli di PB e IB e poi se possibile vorrei implementare una semplice e usabile GUI. Colgo l'occasione per annunciare che sono stati raggiunti i 2000 downloads unici a soli pochi giorni dal rilascio della prima versione :)

Grazie a tutti!
#22 - Bertrand [2007-06-02 20:19:01 CET]

(Dalla Francia)
Caro Andrea, sei un genio ! Grazie per questo magnifico soft.
Il mio Powerbook è stato rubato, poi è caduto da due metri sulla strada... Funziona ancora, ma mi pare che i sensori sono definitivamente out. Quindi, non potevo vizzualizare un film, perchè diventava troppo caldo e avevo paura che morisse di ipertermia. Adesso, posso vedere tutto ciò che voglio.

Andrea: Grazie a te, mi fa piacere che abbia ridato vita al tuo MAC :)
#23 - tomazo [2007-06-03 06:36:31 CET]

Thank´s Andrea! ;-)
#24 - Nicola D'Agostino [2007-06-03 15:20:14 CET]

Andrea: grazie, attenderò nuovi sviluppi. Se dovesse interessare ho almeno altri due Mac portatili più vecchi per test: un iBook G3 800MHz e un Powerbook G3 266MHz, entrambi con sopra Mac OS X 10.4.x. Aggiungo che in realtà il mio obiettivo è lo stesso di Fabrizio Venerandi: non fare partire le ventole prima ma dopo.

nda
#25 - Enrico [2007-06-03 18:54:40 CET]

Ciao Andrea
Il tuo software funziona egregiamente sia sul mio PB17 1,66 che sull iBookG4 1,42 della mia ragazza.
Complimenti e grazie ancora.
Ciaoo

Aspettiamoo speranzosi nuova versione per noi non abili utenti del terminale
e magari script da includere nell'avvio :)
#26 - fabrizio venerandi [2007-06-03 22:12:28 CET]

grazie mille per la risposta. attenderò la versione 'riscaldante' con settaggio dei singoli sensori senza soglie
buon lavoro!
#27 - Antonio [2007-06-04 16:17:51 CET]

Ciao a tutti,
Innanzitutto un plauso a chi si prodiga nella programmazione per rendere facile la vita a noi "comuni mortali". Io, contrariamente a quanto letto sui post sinora lasciati, ho il problema inverso: il mio powerbook 1 ghz 12" dvi proprio non ne vuol sapere di smettere di far girare al massimo la sua ventola...è inarrestabile. Appena ho scoperto l'esistenza di g4fancontrol mi sono subito fiondato a capire che limiti di temperatura avessero i miei sensori. Il programma gira, nella statistica risulatavano soglie minime molto alte (per i due sensori 60 e 90 gradi). Modificate le soglie ad un valore di 40 gradi, però, la mia unica ventola non si dà ancora pace ed imperterrita continua a girare alla massima velocità. Cosa mi suggerite? Un infinito ed anticipato grazie!
#28 - Antonio [2007-06-04 16:21:34 CET]

....dimenticavo....abbassata la soglia non avrebbe senso il mio ragionamento...infatti, se gira la ventola con 60 gradi di soglia minima, gira anche a 40....i sensori rilevano temperature molto basse, al massimo 40 grado per il sensore locale numero 2....non è possibile un reset della gestione ventola? GRAZIE
#29 - fabrizio venerandi [2007-06-05 06:47:16 CET]

caro antonio se hai un pb simile al mio il problema è proprio nel sensore locale: se infatti quelli remoti fanno partire la ventola a 60 e 90 gradi, quello locale parte a 42, quindi appena il pb inizia a lavorare. al momento l'unica cosa fattibile con G4FanControl è settare la temperatura di tutti i sensori ad un unica temperatura più alta (tipo 52 gradi). in questo modo si alza la soglia minima del locale, il difetto è che si abbassano quelle dei due remoti, e quindi la ventola comunque partirà prima del dovuto se si usa la cpu o la gpu... bisogna aspettare una versione del programma che permetta settaggi dei singoli sensori (a noi basterebbe poter settare il sensore locale a 52 gradi, lasciando immutati i valori dei remoti).
#30 - Antonio [2007-06-05 09:50:42 CET]

Ciao e grazie della risposta. Purtroppo, anche quando il sensore locale segna temperature bassissime, la ventola parte forte lo stesso. Spegnendo e riaccendendo il powerbook, ho visto che i limiti temparatura si sono ripristinati ai loro valori originali prima dell'intervento di g4fancontrol, ossia 46 per il sens locale, 64 e 96 per gli altri sensori...mah!
#31 - Andrea [2007-06-06 00:20:20 CET]

Ho appena rilasciato la nuova versione di G4FanControl. Ho esaudito le richieste di molte persone così ora è possibile settare i limiti in modo indipendente per ogni sensore fino a un massimo di 100°. Spero di aver risolto i problemi di compatibilità con alcuni Powerbook come l'ultimo modello a 1.67 Ghz.

Grazie a tutti.
#32 - NSR [2007-06-06 10:10:40 CET]

Original temperature limits on my PB 15'' 1.5GHz:
Sensor0: 64°
Sensor1: 63°
Sensor2: 70°
#33 - PerseP [2007-06-06 11:27:05 CET]

Hi,
it works great on my PB 1.5Ghz 15" with Mac OS X 10.4.9.
Any change on making this project open source?

Andrea: Yes, more changes :)
#34 - Ric_Sky [2007-06-06 15:19:48 CET]

It works great also in my PB 1.5".
Good job Andrea :)
#35 - asteriscme [2007-06-06 23:57:17 CET]

Grazie Andréa, per la vostra applicazione eccellente. Secondo me sarà interessant di disporre di un lanciatore automatico con la parametrizzazione di temperatura. Utilizzo g4fancontrol con "powerbook G4 1,5" e ciò funziona perfettamente.

ciao ciao e grazie.

Sei un mito!

Andrea: grazie :)
#37 - Max [2007-06-07 01:15:34 CET]

Io ho un Powerbook G4 1,5Ghz 12".

I valori di default sono:
- Remote Sensor (1) temperature limit: 65°
- Remote Sensor (2) temperature limit: 94°

Ora li ho impostati rispettivamente a 55° e 80°. Funziona benissimo direi... Complimenti davvero!
#38 - phantom [2007-06-07 02:19:05 CET]

Funziona anche su PowerBook G4 12" 1 GHz con 10.4.9

non le avevo mai sentite...

grazie!
#39 - David [2007-06-07 09:07:26 CET]

Works great on my 1.5 GHz 15" PowerBook. I was very surprised to hear the sound that the fan makes. My 12" PowerBook fan used to come on all the time, but this 15" just seemed to get incredibly hot but no fan ever came on. Thanks for making this easy to use.
#40 - _Olivier_ [2007-06-07 15:32:44 CET]

The new version (v0.4) works well now with PowerBook G4 1.67 Ghz 17" with Superdrive DL (the last version of the PowerBook G4) - Mac OS X 10.4.9

Thanks so much ! (I was dreaming of such a tool)

Is it possible to have the rpm value of the fans ?

Andrea: Probably in the future g4fancontrol versions ;)
#41 - Andrea [2007-06-07 23:33:44 CET]


Ho appena terminato di sviluppare una BETA della versione 0.5, dotata finalmente di interfaccia grafica!
Prima di pubblicarla però vorrei che qualcuno facesse dei test, così chiunque è interessato può richiedermela via email e farmi sapere se funziona.

Grazie a tutti,
Andrea
#42 - Alessio [2007-06-08 00:30:50 CET]

Ciao Andrea.
Ottima utility la tua. L'ho testata con successo sul mio PowerBook G4 17 pollici, 1,67ghz schermo HD, 2gb di ram (l'ultimo prima di intel).
Ho solo uno problema: quando riavvio i setup dei sensori ritorna di default.
E' possibile registrare la configurazione in modo che ogni volta che si riavvia non si debba ripetere l'operazione (non così complicata) da terminale?
A parte questo, tutto funziona senza problemi, e finalmente ho sentito girare anche la seconda ventola mentre renderizzavo un audio-video in SoundTrack PRO.
Grazie.

Andrea: La possibilità di riapplicare i valori preferiti al momento del boot è stata introdotta nella versione 0.5 che rilascerò entro oggi o al massimo domani!
#43 - Andrea Fistetto [2007-06-08 12:39:00 CET]

ho un powerbook g4 15" 1.5 ghz aprile 2004 per adesso la 0.4 funziona bene
attento la gui
ottimo lavoro :)
#44 - Bichufo [2007-06-08 22:47:47 CET]

Very good, specially now with the gui. Congratulations. Is there a way to set the RPMs for the fan because on my iBook G4 it is pretty noisy. FanControl has RPM functionality. Is it possible on this version?

Andrea: Sorry, but with ADT7467 controller is not possible to set the fan speed.
#45 - clem [2007-06-09 09:49:36 CET]

0.5 on iBook 12" 1.33GHz, works superbly.

grazie ancora !!!
#46 - Enrico [2007-06-09 17:13:19 CET]

Ancora più comodo e semplice di prima!!

Grazie per l'ottima utility!!!!

Ciaooo

Se posso permettermi aggiungerei a cosa si riferiscono i sensori in modo da sapere su cosa stiamo agendo......
mi spiego aggiungerei così:

Sensor (1) - Processor/Controller Bottomside
Sensor (2) - Processor Bottomside
Sensor (3) - Power Supply Bottomside

Andrea: Ciao Enrico, ti ringrazio per il suggerimento ma non è possibile metterlo in pratica. Infatti su ogni modello di iBook/Pb a 12/15/17'' i sensori sono disposti in maniera differente, quindi le etichette sarebbero corrette solo per alcuni modelli e non per altri. Per questo motivo, almeno per ora, lascerò nomi generici per ogni sensore.
#47 - pedro vasquez [2007-06-11 09:16:33 CET]

#48 - mantegna [2007-06-11 10:37:05 CET]

ciao ho provato su un ibook g4 14" ultimo modello e funziona eccellentemente.
controllando le temperature dei sensori anche con istatpro penso che il sensore 1 registri la temperatura in zona ram, il sensore 2 in zona cpu ed il sensore 3 in zona HD ( constatato direttamente per il raffredamento della plastica del case in quella zona ).

ciao e grazie
#49 - Antonio [2007-06-11 11:52:40 CET]

Gentile Andrea,

ho un powerbook g4 12" dvi a cui la ventola parte sempre, anche impostando soglie minime alte.
E' possibile programmare l'ADT7467 per ripristinare un corretto funzionamento della unica ventola? Grazie
#50 - Antonio [2007-06-11 11:57:15 CET]

Ho notato che con linux esistono dei driver per la gestione dell' ADT7467....chissà che le sorprese non finiscano qua...:-)
#51 - iBook G4 Man [2007-06-11 15:52:53 CET]

My iBook was set to have it's fans cut on at 80C. that is outrageous. I set it to 60C on one sensor and on the other 2 55C. the gpu gets really hot so it was making the fans run more that they are off. but at 60C i can run my applescript to make the screensaver my desktop background without the fan cutting on often. My iBook does not get too hot to use on my lap now!
#52 - Vbook [2007-06-12 08:00:43 CET]

i wonder that inorder to make the app work. Do i have to leave the app open all the time?
Does it run in the background?
#53 - Esteban [2007-06-12 14:27:16 CET]

Thanks for this app!! My powerbook was getting too hot when CPU power was demanding (e.g., watching YouTube videos) and it was going to sleep... Now I set the sensors at a lower temp and it seems to be working better, but the fans run most of the time. However, once in a while I see a temp of 255 flash in and out.... I have read in the Apple Support Forums that a lot of people with G4 Powerbooks are having overheating problems with the latest system upgrades (I am running 10.4.9). Any comments?
#54 - Denis@ [2007-06-12 16:29:45 CET]

#55 - Aimos [2007-06-13 14:37:51 CET]

Ciao Andrea...,è da molto tempo che non sento più girare la ventola del mio powerbook 12" 1,5 Ghz ultima versione.
Ho scaricato il tuo programma e ho variato i cursori..,ma niente (dovrei sentire subito le ventole girare?)
Oppure mi è partito qualcosa nel mio powerbook?
Ti ringrazio a priori!

Andrea: Il tuo modello di Pb è supportato da G4FanControl, quindi il fatto che tu non senta le ventole accendersi sicuramente suggerisce che c'è un problema (o in g4fancontrol o nel tuo mac). Quindi ti consiglio di provare la versione da terminale per evidenziare eventuali errori di comunicazioni con il controller.
#56 - Pierre [2007-06-14 11:16:39 CET]

Just wondering why does G4FanControl try to connect to the internet when I launch it? Version 0.5 does that, as reported by LittleSnitch.

Andrea: G4FanControl try to connect to internet to check for new version availability.

Just wondering, I try using G4fancontrol (0.5) on my 15" PB but it doesnt work ... I click the icon ... it appears briefly on the dock and dissapears ???


any ideas why?


cheers ...



Andrea: Ensure that you have installed the JVM (Java Virtual Machine). Also try the G4FanControl command line version.
#60 - Gica78R [2007-06-23 19:53:51 CET]

Ciao! Ho un PB G4 12'' 1,5GHz e, come altri, ho il problema delle ventole sempre accese. Ho risolto immediatamente alzando leggermente i limiti di temperatura con G4 FAN Control (e per questo ti ringrazio enormemente), ma mi rimane un dubbio: usando l'utility Temperox (http://www.branox.com/Temperox/Temperox.html) leggo informazioni circa la presenza di due ventole, la prima (Rear Left) è quella che si sente e che riesco a governare variando i limiti di temperatura, la seconda (Rear Right) gira sempre tra i 36 rpm ed i 39 rpm, e in nessun caso riesco a variarne la velocità. E' perché la GPU non mi sale mai oltre i 52 gradi, o forse è possibile che la ventola sia danneggiata? Ho smontato il case del pb, ma vedo una sola ventola: http://img232.imageshack.us/img232/1972/1306072039fo4.th.jpg


Ciao e grazie ancora! :-)



Andrea: Molto probabilmente il programma che usi per monitorare le temperature tiene conto dei 3 sensori e delle 2 fan che può gestire il controller ma senza verificare il modello del Pb e quindi non si accorge che trattandosi di un 12'' ha solamente una fan montata. Se l'unica fan montata è controllata dal sensore presente sulla GPU il problema è sicuramente quello che hai suggerito tu, ovvero che non va al massimo della potenza finché la temperatura della GPU non sale alle stelle. Nella nuova versione di G4FanControl che sto sviluppando sarà disponibile la funzionalità di controllo diretto della velocità delle fan (bypassando i limiti dei sensori) così il tuo non sarà più un problema.
#61 - antonio [2007-06-26 16:47:01 CET]

Ciao Gica, benvenuto tra i possessori di powerbook 12" con ventola al massimo...:-).... Non avrei alcun bisogno di dare ragione ad Andrea visto che ha sempre ragione, ti dico (e spero) che secondo me questa cosa si potrebbe sistemare...ahimè programmatore non sono, a questo sta pensando Andrea (ovvio che merita quanto prima una donazione, mi impegno a farla)...Buona giornata...p.s: il tuo powerbook ha perennemente la ventola al massimo? da quando accendi a quando lo spegni? A me si comporta così..ciao!



Andrea: Grazie Antonio :) Spero che la prossima versione potrà aiutarvi! Purtroppo sono molto impegnato con il lavoro in questo ultimo periodo quindi non so quando sarà in grado di rilasciarla.
#62 - antonio [2007-06-28 14:30:05 CET]

Sono io che ti ringrazio, soprattutto per dare la possibilità del download gratuito e in parallello la possibilità di fare una donazione. Capita molto spesso, invece, che la "donazione" sia obbligatoria previa area download inaccessibile...Buona giornata e buon lavoro...P.s: se avessi la benchè minima conoscenza di ambiente mac os ti avrei dato volentieri una mano nello sviluppo del software o sulla analisi dell'hardware..

Hello Andrea,thankyou for this great little application,
I have some temperature information I would like to share with anybody using G4 12" Powerbooks and is wondering whether they are running to hot and what could be the cause.For measuring I use Temperature Monitor 4.11 which is also available for free out there.
Anyway,I have been using a 1.33Ghz with 1.25GB and a 60 GB/5400 Hitachi drive over the last year and was never bothered either by excessive heat or to much fan noise.
Watching movies and being on the net or,using live(music production app)at 80% would make it hot but the fan ran seldom at full speed.
Lately I upgraded to 2nd Powerbook,the slightly faster 1.5Ghz model 12" and finally installed my 80GB 7200rpm Hitachi Travelstar I had waiting,thinking at last I could push my applications a bit higher.
Although I must say that this 12" has definitly got snappier,I cant really say much about the power gain with applications at the moment because I have been spending time dealing with.....heat,lots of it..and lots of fan noise.

Now,I am not fussy but the little blower in these 12" is quite annoying when it runs at full blast while listnening to itunes & surfing the net.So I went about trying to find out what was wrong.
I had built the 1.5Ghz from scratch myself,because the original housing and powerplug had been damaged so I had the chance to take every part out of the PB and put it in its new skin.
When I switched it on,things got hot,I did it again thinking maybe I had overseen heatsink mounts,or simply made a mistake,practice makes you a master.Everything was fine.
I thought,okay you have more power which might mean equal more heat...I was not happy.
So I set up both computers running exactly the same apps at the same time and then I saw it,the 1.5Ghhz processor Topside/graghics die were running the same or slighly cooler but the 7200 harddisc was cooking at 55 degrees celsius adding heat to the other components & processor and driving the overall temp so high that the fan would run at top speed.
The Hitachi 7200rpm 80gb has the number:HTE721080G9AT00 and seems to run at least 5 degrees hotter than its older brother.The area on the left of the trackpad gets too hot for my taste and the fan can't seem to get enough air through the housing.
I would like to know if anybody else has these issues or experience,I have screenshots but dont know how to post them here...I am more of a mac'chanic than a programmer.

Here are the temps running both g4s at full throttle:
1.33ghz 1.5ghz
harddisc 5400 7200
HD bottomside celsius 47.2 53.6
Processor topside celsius 57.2 59.2
graphics processor die 66.0 65.0
battery 36 36

both g4s running on mains supply

Have been searching nonstop for a fix for my 15" 1ghz Titanium powerbook fan that comes on at 28 to 31C and stays on forever, even without much CPU activity. I am running OS10.10 currently.
I was overjoyed to find the G4 FanControl. But... after multiple downloads of 0.5, and trying to open it up with clicks on the fan icon, it does not open up. I read one of the posts on July 1 that Julien had an aluminum 15" 1ghz and it worked on that machine. Any help, Andrea, would be appreciated greatly. larry
#67 - Andrea [2007-07-05 20:20:41 CET]

IMPORTANT:
Should you experience any difficulty in starting the G4 Fan Control GUI, be sure that your JVM (Java Virtual Machine) has been upgraded to version 1.5.
#68 - Matteo [2007-07-05 21:19:51 CET]

Ciao ti scrivo perchè, come nuovo utilizzatore di mac osx ho un bel problema :

io ho un iBook g4 800 mhz con installato mac osx 10.4.10 il problema e che una volta che scarico il g4fancontroller e lo pongo sulla scrivania vado per aprirlo e lui balzella per qualche secondo sulla dock e poi scompare senza lasciare traccia ...

Sapresti aiutarmi ???



Andrea: Leggi il commento appena sopra il tuo...
#69 - Larry [2007-07-06 00:39:09 CET]

Thanks for you advice, Andrea. I did install the Java update and was able to open up G4 Fan Control GUI. I set the "Threshold Settings" where I wanted them, but then the "Current Status" readings all said "N/A". There were no actual readings from any of the temperture sensors. It didn't read any of the sensors. Any suggestions? gratefully Larry
#70 - Larry [2007-07-06 01:18:40 CET]

I shut down my 15" TiBook. Then I booted it to see if the Threshold Settings I had put there would be there on boot time. They weren't. I did notice that when I adjusted the Threshold on a sensor fader it did show that value for an instant on the Current Status, Sensor ( )Threshold section of the window. But it never showed any actual Sensor temperature readings.

Andrea: Thank you Pedro :)
#72 - Matteo [2007-07-06 19:10:09 CET]

Oh !! scusa davvero nn avevo fatto attenzione .... ho aggiornato il sistema e tutto va a meraviglia prima le ventole partivano a 70 gradi !! adesso a 50... Il programma è utilissimo complimenti


P.S. é proprio vero che la mela come sistema operativo è avanti anni luce rispetto microsoft
#73 - Larry [2007-07-07 00:00:40 CET]

Hi Andrea,

My continuing story about reseting the fan turn on temperature on my 15" 1ghz titanium powerbook, using OSX.
Using Istat Pro and also TemperatureMoniter, it shows just one sensor reading, on the SMART disk Fujitsu.
I had set the all 3 G4FanControl Thresholds to 60C. I shut my computer down overnight. The G4FanControl folder is in the Library Startup Items with 3 files in it, "G4FanControl", "G4FanControl.bin", and "Startup Parameters.plist". The fan went on at 37C, not 60C.
Should my 15" Tibook show 3 sensor reading (as G4FanControl has 3 moniters) on the Istat Pro and TemperatureMoniter programs or just one? Why doesn't FanControl show the Current Status on the one sensor? Do you think I have a bad sensor or sensors? How can I check that? Many thanks for your help Larry
#74 - Alessandro [2007-07-07 18:14:52 CET]

Thanks Andrea,
It's a very useful application!

Alessandro
#75 - Larry [2007-07-08 00:06:47 CET]

Are the older versions of G4FanControl available for download somewhere stil? Maybe 0.2, 0.3 could work on my
15″ 1ghz titanium powerbook. 0.5 does not seem to set the limits although it is installed in a folder in the Startup Items folder of the Library. many thanks for your help. larry
#76 - fragile [2007-07-08 04:37:45 CET]

It's really a great program which i was looking in several years! excellent!
however, the boot-setting option in the GUI version could not work on a certain situation. i have ibookG4/800 with OSX 10.4.10 and settle it into Safe-Sleep mode which is known as hibernation sleep mode suspend system to DISK instead of suspend to RAM. Resuming from Safe-Sleep, you have to re-power it but not press any-key. so, system will reload all context from DISK restart but re-powered. in this case, G4FanControl lost the threshold settings then reset them to system default. To deep into Safe-Sleep, enter "Safe-Sleep" in a box of google. Thank you for great program made!
#77 - mathias [2007-07-10 15:34:11 CET]

ciao,
complimenti per il programmino utile e introavabile prima d'ora!
io ho un ibook g4 12" (preso nell'ottobre del 2005).
due domande:
- io uso MenuTemperature.app (1.5.3) per monitorare la mia temperatura, ma i valori indicati dal tuo programma e da questo differiscono di qualche grado. la differenza varia: o è pari a 0, o a 1° ma può salire anche a 6°. hai una spiegazione?
- dato che mal sopporto le ventole e in estate tendono a partire più spesso ho alzato leggermente il limite. sai quali sono limiti accettabili entro i quali nn succedono casini ai componenti hw?

grazie mille
ciao
#78 - Kip [2007-07-14 03:12:04 CET]

It works great on my Aluminum Powerbook G4 15" 1.5 G. Thank you so much for making this app. My legs are much happier now that they are no longer getting burned anymore. :-)

Maybe I missed it, but what are your recommended settings?
#79 - Andreas Linde [2007-07-14 14:16:49 CET]

Andrea, this is a gorgeous idea! Sadly I am running a Powerbook Titanium 867 DVI, which is not yet supported. Hopefully you will be able to add support for that model too, would be happy to donate then :)

If you need any assistance, any time!

Ciao
Andreas
#80 - cilly [2007-07-14 21:13:14 CET]

Hi Andrea,

safed my fingers from burning, georgious app.

I still have some questions:

1. Where are the fan-control settings stored? I assume in the NVRAM... but just wanted to be sure.

2. How do I set the individual fans directly from the command-line? I am planning to put the commands into rc.local, just to make sure, they are set at boot-time, i.e. if PRAM is zapped...

Thanks a lot
#81 - cilly [2007-07-14 23:34:40 CET]

oki, with version 0.4 now everything is easy :)
#82 - Carl [2007-07-15 17:27:09 CET]

How do I make it run? I'm using a 12 inch iBook G4 1.2ghz. Thanks.
#83 - pnigro [2007-07-19 14:03:29 CET]

Works great, but why does it ask for my admin password everytime it launches? I added it as a startup item, but this behavior kind of cancels out any benefit to that
#84 - Jason [2007-07-20 06:00:16 CET]

Wow! My TiBook has fans! I've had this 15" 1.67GHZ G4 for about 2 years now, and always had problems with it being too hot to use on my lap when doing anything intensive. I installed your program and started it up and my default settings were 64, 63 and 70. I had never heard the fans kick on until I backed the temperature settings down with your program. Now I can actually use it on my lap without needing a fireproof blanket. Thanks a lot for this application!
#85 - Kristoffer Holmén [2007-07-20 09:51:37 CET]

I like it, nice app, just one question; wich of the sensors (1, 2, 3) shown in the application is GPU, CPU and wich i the third sensor (0.5)?
#86 - Kristoffer Holmén [2007-07-20 10:09:25 CET]

0.5 is my version of the program. I see it was a little unclear...
#87 - Blower [2007-07-20 16:18:17 CET]

All this would help if we were told what OS it works on and simple instructions were given out to those who are not so computer literate. Anyone come across a simple fan control application for 10.3.9 yet?
#88 - pedro vasquez [2007-07-24 05:27:19 CET]

pa ra el que no hable italiono ni ingles....


para correr este programa necesitas... un ibook o un powerbookl g4... da lo mismo la velocidad....
tener actualizado la maquina java.... eso se logra desde actualizacion de software...
yo empece con el tiguer 10.4-- y he ido paulatinamente actualizando osx....
hasta el actual 10.4.10----

asi que lo mas importante es la vjm actualizada..popr que si no no va a correr...


y agracescan que andrea hizo este programa...
#89 - pedro vasquez [2007-07-24 05:28:56 CET]

java 1.4.2...
#90 - Colin Santos [2007-07-24 20:20:57 CET]

This is a great program. One question, does the constant use of the fans reduce their life span? Just wondering.
#91 - Sheila [2007-07-25 05:09:26 CET]

I understand that JVM=1.5 but I can't seem to validate / find out how to download install if necessary. I've tried the latest java download on Apples site, but that doesn't seem to do anything. Please help. All I get is the icon flashing briefly and disappearing.
#92 - Todd [2007-07-26 06:46:29 CET]

To: Sheila - There is no java 1.5 for OS 10.3.9. Only 10.4.x updated will work. You will need to use the command line version.

To the Developer: Perhaps someone like yourself or someone reading this thread can offer a suggestion why the following...Fan is always on. Period. Turn the Powerbook (12" 1.33GHzz) from dead cold in the morning and fan is spinning at 8700RPM approx. (Does vary slightly). No matter how cold the machine is the fan is spinning madly away. All the sensors are well below trigger temps. Tried G4 FanControl along with the other Powerbook fan resolutions (backdating kext files etc). The fan is always on. iStat shows something sort of interesting in that it lists the Hard Drive temp as 37degC and also lists ST980815A with a temp of 32degC? The ST980815A is the hard drive. Which brings me to more important info... the hard drive was replaced - the original died. I never experienced it or its fan until it came to us (we are a service centre). We put in the Seagate 80Gb ST980815A and when re returned it the customer was compaining about the fan. Days backdating to 10.3 and back up to 10.4 etc did not help. Any suggestions why this suck only knows one fan speed? After meticulously going over every step in the hard drive replacement I can't see what may have been damaged or altered in replacing the hard drive. Thanks in anticipation

Muchas gracias!! Miro que mas de media personas aqui han escrito en espanol - estoy tratando por eso, pero solo puedo hablar un poco... y a escribir menos. Quiero decir que este programa ha reparar mi computadora - durante la semana pasada un problema de calor rota mi PowerBook G4 y despues solo podado usar para quince a vente minutos antes de se hace dormir. en la programa Console, se dice que ha dormido porque esta tan caliente. este programa de usted hace que puedo usar por una dia completa sin problemas.

gracias y salud

#95 - jeff [2007-08-13 17:07:17 CET]

THIS PROGRAM IS AWSOME!! but i would like the program to allow u to have the fans on all the time but not so loud. Thats it.


thanks

#96 - Thomas [2007-08-14 01:19:12 CET]

Dear Andrea,

I am very intrigued by your G4 Fan Control application and I am thinking it might be possible to modify the code to change the Specified Upper Limits for when the computer will go to sleep if the computer overheats. The reason this would be of use is that there is a fairly common problem of the Powerbook G4 Trackpad temperature sensor to break and report temperatures of well over 100 degrees Celsius, prompting the system to go to sleep. If the Specified Upper Limit could be changed, the broken trackpad sensor would not cause the computer to go to sleep randomly. The problem itself is reported for example at these sites:
http://www.swisswuff.ch/joomla/index.php?option=com_content&task=view&id=24&Itemid=78
http://discussions.apple.com/thread.jspa?messageID=5006452
http://www.macfixitforums.com/printthread.php?Cat=&Board=Forum35&main=731197&type=thread
http://forums.macrumors.com/showthread.php?p=3374135
http://web.mac.com/rickcameron/iWeb/Electric%20Lamb/N.A.P./N.A.P..html

The last website even recommends physically removing the broken sensor to fix the problem. It would be much easier to just increase the treshold value to prevent sleep in case of the trackpad sensor sending erroneous overheating signals.

This would be a great addition to the program though it does go beyond fan control.

Hi, I'm using 10.3.9 and so it seems can't upgrade the java to the correct veriosn to get the GUI version to run. Sooo excuse the stupidity but what exactly do I type in to terminal if I want to set the temprature to say 30?
Mnay thanks

Please make it compatible to Java 1.4.2 so people with Panther can run it... Many people with G4 still use Panther. Thanks in advance. =)
#102 - Pedro Aldana [2007-09-23 01:48:23 CET]

Muchas gracias por el tiempo y la dedicación para crear este programa. Solo teengo una pregunta como hago que los ventiladores queden siempre a maximo RPM aunque reinicie? gracias.

How can i make permanent the change? even if i reboot? i neet the fan spee always at full RPM... my temp sensor is not working any more. Please i really need to know this please.
#103 - Luca Marchesi [2007-09-24 10:14:45 CET]

Il mio iBook G4 1.33GHz OS X 10.4.10 ora è freddo! Avevo anche comperato un supporto con tre ventoline ma quasi inutili, e non avevo (quasi) mai sentito la ventolina integrata girare così.
Applicazione stupenda! Ti offrirei una birra!
#104 - antonio [2007-09-26 20:00:54 CET]

#106 - A.R.Vojdanitalab [2007-10-09 18:59:39 CET]

hello Andrea

i'm using ur fancontrol tool for 2 days now.

i found out something intresting trough your tool.

i think the problem of too loud fans can be solved with a modification of your tool.

i found out that when you turn down the sliders at start up to the actual felt temperature of the sensors ,the fans become quiet and then you have to turn it back to higher values arround 56 .C

as i could see your program offers a saving function which can be used at each startup , i think it would be good if you would expand your program that way that it fetches the startup temperatures and sets the threshold to that values and turns them up again to saved values which are arrond 56 .C .

#108 - Meg [2007-10-26 01:00:41 CET]

Thank you so much for writing this program! It rescued my Powerbook from overheat and random resets!

Do you know if it will work with OSX 10.5 (Leopard) when it comes out?
#109 - Alex P. [2007-10-28 09:44:29 CET]

It works with leopard too, great!!!
#110 - Diana [2007-10-29 10:39:24 CET]

For those who are using it with Leopard, did it cause any problems during installation?
Did you remove the tool and re-installed it or did you just leave it as it was?
I'm going to install Leopard with archive/install and I don't want to make a mess of my PB.
Thank you
#111 - Martin [2007-10-31 15:15:45 CET]

So Many thanks, I have spent way to long hunting down info and was about to hard wire the fans full time. This must be the only program there is. Cheers again. 1Ghz titanium G4 powerbook (fw800)
#112 - Hal [2007-11-01 09:51:45 CET]

It doesn't work here! I find that strange since others with similar systems have no problems.

My Mac is a 15" PowerBook G4 1.67GHz (dual layer Superdrive, backlit keyboard etc.). I'm using MacOS 10.4.10, and have G4FanControl 0.5.
When I run the application I'm asked for the administrator password, then a new window entitled "G4FanControl 0.5" comes up, but it's completely blank!
#113 - Hal [2007-11-01 13:10:20 CET]

I'm having problems getting it to work.
I'm on a 15" PowerBook G4 (1.67GHz, dual layer SuperDrive, backlit keyboard etc.) with MacOS 10.4.10.
When I run G4FanControl I'm asked for the administrator password which I enter, then a new window comes up, but it's completely blank. I also noticed that it attempts to go online (I can see this because "Little snitch" is installed) -why does it need an Internet connection, and can this be part of the problem?
#114 - Diana [2007-11-03 19:01:11 CET]

So... I'm using G4FanControl under Leopard now... it works fine, BUT it no longer remembers my settings after a reboot, I have to change them again every time I switch the Powerbook on (which btw doesn't happen very often).
It would be nice if you could find a way to fix this problem. Thank you!
#115 - MAEG [2007-11-05 08:52:00 CET]

Works like a charm with Leopard on my 15" 1.25 PB. however doesn't remember settings after reboot but thats ok. Thank you for a great program.
#116 - Lorre [2007-11-12 10:56:02 CET]

#117 - Andreas [2007-11-17 23:19:37 CET]

Thank you so much for a fantastic application. Downloaded, installed and opened on my PB 15" alu 1,33 ghz Tiger with no problems what so ever. I actually thought my fans were out of order, but now I know they work. Because of this application, I get to love my PB even more!!
#118 - Mick [2007-11-18 21:55:54 CET]

Same thing, would be nice if we could get a fix for remembering settings after reboot in leopard
#119 - Guillaume Jamet [2007-11-27 10:37:36 CET]

Hi!
I must thank you : I firstly thought my Powerbook's fans were not working, as the Mac get pretty hot and no fan were starting at all... Your program let me test them with success and *absolute thanks* tweak the threshold temperature. Now my Mac runs a lot cooler. I prefer hearing a little noise from the fans than fearing a total meltdown of the whole computer :)

Just to mention : i'm using a Powerbook G4 15" 1.25 GHz running Tiger 10.4.11.
#120 - spironox [2007-12-06 18:22:47 CET]

thanks a lot my friend for such and excellent tool

i would ask with others

what should be the threshold temp of sensor 01, 02, 03

i mean i am using IbookG4 12"

with a power pc 1 Ghz chip

suggest please
#121 - Emilie [2007-12-07 15:06:04 CET]

Thank so much...

I have a PowerBook G4 17''-1,67 GHz and from the beginning the fans are ALWAYS ON! they stop only when CPU is full used. I had to take so many Aspirin to bear its noise. Now with your program I can just fix it. It's still really strange how my PB's fan act. thanks again.
#122 - Maximus [2007-12-20 16:59:17 CET]

I would like to see a continuation of the topic
#123 - Glitch [2007-12-21 23:29:34 CET]

AWESOME APP!!!

This was exactly what I needed to keep my Powerbook cool.

I agree with you, it seems very strange that Apple has chosen to put the temperature thresholds so high. Perhaps to alleviate the volume of complaints from people who can't handle the additional fan noise.

I, however, couldn't care less. That's why headphones were invented!

So, thanks again for creating this!

I will be making a donation very soon!
#124 - robin [2008-01-06 02:30:26 CET]

Hi Andrea! I have been looking for such a tool as yours for a very long time now, the constantly running fan(s) of my G4-Powerbook (no matter what I do with it, like writing email to you now) are driving me crazy. BUT, WHAT A SHAME !!!!!!!! It does not work with my G4-1GHz-TitaniumPB (OS10.4.10, updated to Java 1.5) WHY IS IT SO??? Did G4 start for you with AluPBs only? What about millions of previous G4 PBs? (Sad) Robin
#125 - Clas Peterson [2008-01-19 10:04:43 CET]

THAAAANKYOU :-) I had problem the other way around. Since I installed OS X 10.3.9 instead of 10.3.7, the fan(s) on my PowerBook 12" Alu 1MHz started to spin all the time. Somehow it seems that Apple lowered the temperature limit to a ridicuolus level which in reality mean that the fans are spinning even when no applications were running...!

I downloaded FAN Control and checked the stats. The temperature limit for the local sensor was 46 degrees. By raising this limit to a reasonable level, the fans now kick in when really needed, instead of all the time :-)

It's a shame that this app should be needed though. This should be working in OS X without the need to download other software.
Thanks again. GREAT APP!!! :-)

Can someone tell me where I can find the default temp settings for my PowerBook G4? I changed it with this program and I no longer know what the default settings are.
#141 - wax [2008-05-23 18:27:10 CET]

Default settings for an iBook G4 (last version - probably same settings for a PB):
Sensor 1 : 56°
Sensor 2 : 76°
Sensor 3 : 85°

#144 - Sebastian [2008-06-13 21:38:22 CET]

Hi!!! I have a PowerBook G4 1 Ghz FW800, and when the machine get hot, the machine doesn't work, the system frezzing, after that i shutdown the computer, and try a couple times and the same happend, i let the machine get cold, and when i do that, i come to work... Someone can sayme if i can use this program to fix it? Thanks, Sebastian. (Sorry for my English)
#145 - Rob [2008-06-14 10:09:00 CET]

Yes Sebastian, i have the same problem and i have solved with this software!

como se instala g4fancontrol 0.4 no se programacion y es completamente nuevo para mi
#149 - Trevor [2008-07-17 21:51:33 CET]

From comparing this app with the Temperature Monitor app, it seems that the sensors in G4FanControl correlate like this:

Sensor 1: Hard Disk Drive Bottomside
Sensor 2: Processor Topside
Sensor 3: Graphics Processor Die

Temperature Monitor also gives "Specified Upper Limits" for these readings, which will help those of us (like me) who are using the Fan Control to actually turn *off* the fans (which can go crazy under Leopard). Here are those max values (in degrees Celsius):

Hard Disk Bottomside: 59.0
Processor Topside: 79.0
Graphics Processor Die: 103.0

These max values make sense with the default settings (46, 65, 94) that come with the PowerBook G4. The main issue in my case was not the processor overheating, but rather my hard drive. I bumped the limit for the fans up from 46 to 50 on the hard drive (sensor 1) and now the machine runs quiet. I've got the hard drive backed up, and losing the hard drive would not be as bad as losing the processor (I could just boot to the backup drive). Now at least I know what the implications are, I think.

Cheers,
Trevor dC
#150 - john [2008-07-25 02:55:49 CET]

Much thanks. I've been looking for something to control the heat on the bottom of my G4 and this works great. Before I lowered the thresholds my G4 was 64C! It was too hot to touch let alone put on my lap. Now it's running along at a comfortable 39C. Great job. Thanks again.
#151 - UD [2008-07-25 16:22:29 CET]

Initially my G4 getting overheated, but after installation this software controls temp and i am happy.

Grrrrrrrrrrreat Job.

Thanks a lot
#152 - rebee [2008-07-31 05:41:58 CET]

This is Brilliant!
I spent over an hour at the genius bar yesterday to find out if my fans were fried because my computer was shutting itself down because it was getting too hot (at least they confirmed my suspicions!
Your freeware will hopefully solve my problem (my G4 is about 2.5 years old and overheating/shutting down has never happened to it til now..)
Thank you big time for this! I hope it solves my problem! Big hug!

Bought a g4 powerbook used to replace my pismo, so it could also double as a "widescreen" desktop to run my sony 24" widescreen CRT. But it kept freezing. Did some google searching and found this...
Fantastic..!
One thing though..Could you recomend settings for using with Power cord, and using with battery.

#157 - SegamanXero [2008-09-01 08:16:01 CET]

have 12" powerbook G4, and it use to get really hot when i used it. other then the heat problem, it does not give me any problems. I actully was thinking the powerbook didnt have a fan built in, as it would get so hot that i could cook a nice omelette on it. I came across a older free version of this on anther website. I used it for several months and it save me many burnt laps... after using the older version, I decided to support the author and thank them by buying the full version... its really a life saver... well at least to my macs life, lol!

but thanks for your hard work and wonderful software Andrea!
#158 - bror [2008-09-01 13:14:22 CET]


Great Software
I would add a second vote to having the RPM of the fans shown on the control - not necessary but something nice to have. On the widget with a dial of the rpm next to the temp would be very very cool
#159 - Teridon [2008-10-06 19:33:31 CET]


Thanks very much for the excellent software.

A request: Can you make it so that GUI updates itself if the settings are changed from the command line? The "Current Status" threshold readings are updated, but the slider bars under "Threshold Settings" are not.
#160 - Marc [2008-10-25 13:36:30 CET]

This is brilliant. I changed the case on my 1.67ghz G4 and forgot to replace the thermal paste when I replaced the logic board. Naturally, it started to overheat and started shutting down without notice. This application has saved my bacon!

For what it's worth, on my machine when using TemperatureMonitor, Sensor 1 is Processor/Controller Bottom, Sensor 2 is Processor Bottom and Sensor 3 is Power Supply Bottom.

Thank you for this application.

#163 - claudia [2008-11-22 06:04:03 CET]

I put Leopard on my G4 (10.5.4) last spring and sense then it has been overheating and turning itself off. We replaced a fan and upped the memory to 1.25 and got G4 fan control, but it either has the fan running all the time or turns off. Right now the sensors are set at 23, which is low, but it is not turning off. The thresholds are at 39. Does anyone know a setting that works? Is the problem the Leopard installation? Would it be better to take it off? Thanks.
#164 - Fab [2008-12-08 11:55:34 CET]

Peace is back . . . for only $8. Just dragged one of the slides (in my case, Sensor 3) and my G4 immediately became quiet. Earlier, after a full day of work, sometimes I had that awful sound of the fans in my ears even at night. Actually I found out that the problem was a permanent overplus of only 2-3 degrees, but the fans were continually running.

Have been using G4 Fan Control for a couple of weeks now, with no loss of performance or any other problem.

Thanks a lot!

Hi there, will this app run on panther (10.3) I have a problem where as soon as the fan stops the screen freezes but is fine while fan is running, so if i can get the fan to run all the time it would be great and also i will be able to upgrade to a later os. thanks, jonnyxx.

Ciao Andrea, ho un problema con un PB G4 12" 1.33 MHz.
innanzi tutto la descrizione della macchina:
Powerbook G4 12 pollici 1.33 MHz
Hard Disk da 40 Gb Apple
Airport Extreme
ed ora se hai un minuto ti descrivo brevemente il problema:
il powerbook si congela usando l'airport e non ho mai sentito partire le ventole.
Monitorando la temperatura con Temperature Monitor vedo che quando uso l'airport le temperature salgono a dismisura, non risponde più ai comandi e poi si congela mostrando il monitor blu.
Inoltre se uso un Hard Disk esterno Firewire tutto questo non succede.
Pensa che mi è venuto in mente di metterlo in frigo, si non scherzo! Proprio in frigorifero. Dopo due minuti lo tiro fuori e lui riparte tranquillo.
E' incredibile... non ho parole!
Sono un utente mac dal 1994 e non mi era mai successo di vedere una cosa del genere.
Cosa posso fare? Pensi che usando il tuo software risolverei il problema? A che temperature mi consigli di settare?
Grazie in anticipo
Stefano
#171 - Pepe [2009-05-24 18:33:56 CET]

Funziona benissimo sul mio powerbook g4 (1,67 Ghz PowerPC 17"). ho dovuto cambiare hd di recente. ora ho un 250gb e leopard 10.5.7... con g4fancontrol posso anche lavorare senza friggere le uova sulla tastiera :)
Grande davvero.

Una sola domanda: ci sono delle impostazioni "consigliate" per le temperature?

Grazie in anticipo

#173 - Robert Poor [2009-06-17 17:00:23 CET]

This is a handy application! Do you have any insights how to read (and modify!) the temperature limits for the trackpad sensor in a PowerBook G4 aluminum (running 10.5)? I think this uses a different sensor than the ADT7467.

Like many users, the trackpad sensor in my machine has gone bad and is reporting impossible values (e.g. 90C), which causes my machine to shut down.

Any insights appreciated!

Best regards,

Very simple program that works nicely. The Dashboard widget is also a nice touch. Fan operation had previously been driving me crazy on a 12-inch PB G4 currently running OS 10.5.8. Having manual control to lower thresholds to initiate cooling sooner is worth the purchase price.

I am using in conjunction with the iStat Pro Dashboard Widget which gives some more temperature information as well as fan speeds.

G4 Fan Control is working great on my G4 12" powerbook. Well worth the fee.
#181 - jay [2009-09-09 00:52:27 CET]

I have passed the control panel and widget onto others who have cooling issues with their macs, Apple wont admit to the fan control issue, they rather have the mac burn up so your forced to purchase a new one, this ibook g4 1.33 12" was bought may 2006 and still holding on strong, thanks to this control panel, I have not had any issues with this fancontrol software, as doing graphics and music on this mac. Make sure the java script is updated, the older versions will not work with this control panel, im running os 10.4.11
#182 - Paulo [2009-09-27 20:03:44 CET]

I am currently listening to the sound of my G4 iBook's fan whirring for the first time in months! Thank you. I have been having serious problems with my iBook, which I believe now were the result of overheating issues. I have had numerous disc erases, partitions, reinstall systems over and over again, but I refused to give up, yet each time the laptop got hot, the system would freeze and after a forced restart I'd be back to square one. Hopefully... now I have my fan back, this iBook will keep rocking for a good few years yet. Thank you Andrea!
#183 - Satisfied [2009-10-25 19:04:16 CET]

My G4 was basically non-functional for the past year, going to the screen of death every time I tried to update software or watch a youtube video. I had it on a cooling stand, reinstalled the OS too many times to count, took it apart to make sure the fan wasn't stuck or unplugged ... still no luck.

In less than a minute after downloading this program, my fan started whirring and now I've been putting the old iBook to the test and no crashes at all. I've had as many as 10 windows open, ALL playing youtube videos simultaneously.

OBVIOUSLY heating is a major issue for these old books, and I'm happy to say that this is, without a doubt, the silver bullet. Thank you so much for saving me the price of a new notebook.

Cheers!

Dear Andrea:
Thanks for the G4FanControl app-it works like a charm!

Sure beats my waiting in line at the Apple Store yesterday to see a "Genius" at the "Genius Bar",who then told me I would need to leave my PowerBook overnight so they could run a diagnostic to see if my fans were working and to see why my machine was getting hot. He said it would take "hours" to run it.

When I mentioned your program, he said: "I'd be careful of programs like that". (:@\
He did not seem to know the Apple default temps. for the fan(s) operation.

So I decided to try your program instead. I'm sure glad I did!

Your program should be offered as an app. in the Apple "Widget" store...why isn't it?

At any rate, thanks again for a GREAT application...now my PowerBookG4 runs much better...thanks to your "cool" application!
(no pun intended) (:@)

Sincerely,
Roy

I have had 2 ibooks. 700mhz, and now a 1.33 ghz. When working for long periods, or playing a movie the computer heats up and gets extremely hot. This has scared me with my newer ibook since my 700mhz graphics solder got loose from extensive overheating. My 1.33ghz has done the same, and is unbearable to have on my lap when watching a movie. The original settings never seemed to kick in untill my lap was sweating.... I have just installed your program and it has made me less nervous on my computer overheating for ANY reason. Thank you for diagnosing these settings. Above I have read and from now on you will be saving people alot of time and money. Thank you!!

Hi Andrea,
Thank you for an igenious program! I bought it today to get rid of the noise of the fans, unlike most others! I need to have my powerbook 12 as silent as possible (as close up to the mac mini as possible).
My question is how high temperature setting can be allowed for the machine before its getting hazardous. I would appreciate to know the highest settings for the thre fans that could be allowed with your program?
Greetings from Norway
#190 - Doug Griggs [2010-04-06 22:50:48 CET]

Thank You! I spent hours trying to load rms fan control and smc fan control which were for imacs and or macbook or macbook pro. Instead of being dissed by apple specialists in the store as having an outmoded antique as owner of my G4, I feel blessed that these links are still active for this older machine. Yes guys, when you pay for this, and get the license code, your download will activate, and it will work as you see the icon on your taskbar. I have a powerbook G4 bought refurbished online in 2006, and had this hibernate shutdown problem become more and more frequent after two years. Follow protools advise in that you should open with and "save as" volume to your external drive, and don't work for long periods of times, such as more than 2 hours, using only your computer's laptop hard drive. Having more than one computer is a blessing, if only for giving one a rest. I set my sensors down 10 degrees as suggested, and I could hear fan one kick in and watch temps drop. Using a cookie tin inverted to wick away heat on bottom by battery, turning off Ken Burns effect on screen saver, and the rick cameron site to disable track pad sensor should keep CPU usage low, as I have heard from you powerbook guys that these are all related to (in my case) hibernate and sleep shutdowns. Also, though not my case, freezing and screen breakup is also related . I also suggest, that if you have iphoto, itunes, or garage band open for more that two hours, this could be setting up failure of the heat sink with the compound covering surfaces inside no longer effective. Search: www.macintouch.com/readerreports/powerbookg4/topic2815.html : "PowerBook G4 Heat" is the keyword chain to get to the blog that showed me this great download. Finally! And . . . .Yes, I will now probably buy the new 21" imac which costs almost one thousand dollars less than this 160GB 2mb ddr memory g4, with quadruple the disk space at 5ooGB, but I won't be damned in to a $321 flat rate fee off to Tennesse or Texas, whereby I get my whole logic board replaced!
#191 - robpercy.com [2010-05-19 14:17:19 CET]

I would like to sincerely thank you for your program. I have a powerbook g4 aluminum 12" that I love and rely on heavily. I bought it two years ago, upgraded ram by 1 gig and installed a 320 gig hard drive. I am currently running 10.5.8.

About 3 months ago it started crashing. The screen goes opaque grey with a box in the center telling me in 4 languages that I have to hold down my power button to restart my computer. I took it to a local Mac dealer (independent) who charged me $75 bucks to check it out and they came to the conclusion that there was a "cold solder" somewhere on the motherboard. I was told I could have Apple repair it for $400 which seemed cost prohibitive given the age of my computer.

After bringing it home and trying to use it periodically, I realized that I was getting almost 15 minutes of use out of it when I started it from cold start before it would crash. After that initial crash, if I re-started immediately, it would crash every 3 to 5 minutes until i shut it down for an extended period of time. I talked to a friend who said his g4's fan runs pretty regularly and that I should be able to hear it. I realized that I never hear the fan working so I started to put together the idea that the computer was crashing after it warmed up.

Long story short, (I know, too late) I downloaded your program, ran it, and as soon as I re-set the temps lower, the fan came on. I don't believe it has ever been on before. My computer has been running at full tilt for 24 hours without a crash. The $14 I spent on your program has saved me a thousand bucks that I was going to spend on the new aluminum 13".

Thanks again.

I was trying to keep my old Powerbook G4 running as it has been a really great computer, for what it is, and was using iStat Pro to monitor fan speed and the right fan would never seem to ever come on, even though the laptop seemed to be quite warm most of the time.

So, I purchased this program as a troubleshooting tool to test the fan, but I received so much more benefit from it as I can now control when the fans come on and keep my G4 running even cooler!

Can't say enough about this simple but effective program. It is a MUST for any G4 owner that wants to keep your computer running cool and into the future.

Thank you Ms Andrea! =}

Thank you for using some common sense, real world, everyday geniusness! The results are immediate and pretty dramatic. You have given my old pal G4 17" a longer, more productive lifespan, which means you've helped one of the longest lived but still keeping up Apple machines live even a bit longer! My PC friends hate me enough already, having gone thru 2 machines to my one at least. Thanks again!

Great little program !

When recording guitar tracks with my old PPC G4 portable, there was a squealing sound coming from one of my fuzz pedal when the computer Fan was on. With G4FanControl i can shut off the fan when i'm recording. Also, when i feel the
computer is too hot, i can just adjust the fan temperature tresholds to turn on
the fans. Again, great program that you can live without once you've tried it.

Good work Andrea !

#208 - Helena [2013-01-30 10:17:37 CET]

Hello Andrea,

GRAZIE for this great app. It really has saved my PB G4 1.67 almost 100% though it will still sometimes shut down anyway.I set the controls to about 40 and the fans spin at about 3500.

I do have a question regarding removal of the heat sensor on the logic board. I have read that that is the REAL solution to this narcoleptic issue. I have tried to find info about what happens after removing it. IF I remove that sensor, then will I have fan control at all? Will the fans still run - with or without the G4 control? Will the machine just get hotter? With your application, can I control the fans with or without the sensor?

Thanks so much...I am not sure whether to just leave it for now. Kind of like an appendix operation!

Will this work for my Mac Mini? It runs about 113 degrees F on average. i installed it and it seems not to be working. If not is there one for the Mac Mini, it is a PPC model.

Thanks!

Hi, I have a G4 17inch 1.5ghz and was worried that the right fan wasn't working This App is superb with 10.5.8 Leopard. Changed Fans to around 50 for all three sensors now both fans kick in slightly earlier to help cool the laptop. Worth the £10.23 (converted from $14.99). Loving this old beast of a Laptop.

Many Thanks fro the fast response Andrea to my license query. Keep this website alive there's still a lot of Powerbooks about. And with HTML5 they are making a comeback!

Hi Andrea/All

Just a quick query as I have been reading all of the answers on this website and trying to 'Google search' other answers. I have the 1.5 ghz 2gb ram last of the powerbooks as mentioned before. What are the Default sensor settings that may have been changed in 10.5.8 last software update. I have read on you website different settings of 64,63 and 70 and setting mine to all 50 seems to activate the fans all the time when its on my lap.

I did uninstall the app then reinstall it to see if the defaults would return so that I could just record them for future use if needed but they stayed the same as I had set on the first install.

Do you or anyone know what these defaults are please. I have also seen that they may have changed in the last Leopard updates compared to the first values posted on here from 10.4.xx. (Apple had a lot of complaints of overheating)

Its a great App, that I want to set just slightly lower than default and then leave, just to help prolong the life of this beautiful piece of kit.

Many Thanks

Hello Andrea.

I have a iMac G5, 20", ALS, 2GHz, 2Gb RAM 2.
This machine suffers of chronic overheat, the web browsers demand many use of the CPU, I have replaced bad caps very many times and fix many PSU fails.

Do you create possible to install the App in iMac G5? Work for my would iMac G5?

You don't need the terminal, just click on the installer file.

Does this work on Power PC G5 Dual Processor Tower? Running 10.4.11 and maybe 10.5.8 soon. The intake fan seems to be constantly running very loudly and I can't seem to find any way to slow it down ever. I tried reediting the applefan.kext setting the thresholds higher, but that file doesn't let you specify which fan you are referring to, either way it didn't change the intake fan's behavior, and it is too loud for me, as I run a music studio, and I need the computer to be a little bit quieter than it is. Does this program fix more than the .kext edit can?

Thank you!

Works great! iBook G4 1.07Ghz - running too hot, couldnt figure out why it kept freezing in the middle of something, found this and solved my issues. Gaming is another issue, seems to overtake the fan change and freeze the computer anyway. Perhaps new chip thermal paste, maybe dried up all these years.

OS X 10.3.9

Please, can anyone tell me, why it doesn't work on PowerBook G4 867 MHz?
I tried version 0.4 and 0.5 on OS X 10.5.8

Thanks
