Control fan speed from cli in Tiger? (iBook G4)

Recommended Posts

Hi y'all,

 

My iBook G4 has overheating issues in Mac OS X 10.4 Tiger. The fans work in openfirmware, but it seems that as soon as Mac OS X boots all fan activity stops and the iBook soon overheats and will freeze.

 

Is there any way to control fan speed in Tiger. Either via terminal or a gui app?

 

Thank you!

How did you install Tiger? It kinda sounds like there's a broken driver or something, as that shouldn't happen.

 

In the meantime, I'm afraid I don't know of any fan control software.

I installed Tiger via the 4-disk CD installer, then upgraded to 10.4.11.

 

I also just upgraded to Leopard by putting the iBook into target disk mode and installing from my PowerMac G4. Performance seems better but I still do not hear any fans.
