Fans on PowerMac G5 rev up when asleep

[Boyyo]

Ladies, genitalmen,

Fans on PowerMac G5 noisily rev up when asleep for a while. Have to press the power button to shut it down as it won't wake up.

Any ideas on how to fix this little problemette?

Cheers.

Sounds like you need to reset the Power Management Unit (PMU/CUDA).

Here's a link to the official Apple procedure:
