OK, here is a tip prompted by Hughmac and his ATI Rage 128 video driver kexts.

If you can get a hold of this kext from 10.2.8 Jaguar: AppleADM103x.kext <--- EDIT: NOW UPLOADED
Replace the one in Leopard (or Tiger) with this one.

The kext should be in /System/Library/Extensions

Backup your old copy to somewhere safe, put this kext file in and then repair disk permissions. Reboot.

This allows fans to kick in at at a higher temp...148 Fahrenheit instead of 125 Fahrenheit.

Tip is courtesy of Tom Vilsack.

I will see if I can find my 10.2.8 kext file tonight as it's at home.

If the theory is that being a PPC only distro makes the difference, would AppleADM103x.kext from Panther do the job, as I don't have a Jaguar disk?

Cheers :)

Ha ha, it's 21.20 here, and I have another 2 hours before finishing work and getting home to play :apple:

Cheers :)

What I am not getting: the ATI Rage 128 is passively cooled, so you mean the system fans. The Rage has no temperature sensors as far as I know, so what has the ATI kext to do with the system fans and the temperature sensor of the CPU or the HDD? (older G4s do not even have a CPU temperature sensor as far as I know, right?).

Is that save to let the fans kick in at a higher degree?

Sorry for any confusion. This thread is a continuation of a conversation in a different thread. We thought it would be better to split it off into it's own thread instead of continuing to hijack the other one.

Yes the purpose of this thread is to give PowerBook users an option to use the older kext which turns fans on at a higher temperature. This means you can get your PowerBook hotter before the fans kick in.

Just curious, does anyone know when an iBook g4s fans are supposed to turn on? My laptop gets awfully hot before they do, but they do a surprisingly good job of cooling it down, so I don't burn the finish off my desk ;)

Well I'm actually ambidextrous with temps, so...

Memory/Power 133°F
CPU 169°F
GPU 185°F

and for PowerBook 15" 1.5 GHz they are

75°C CPU Bottom 167°F
76°C CPU Top 169°F
82°C Power Supply 180°F

Cheers Luddites :D :D
