Possibly eliminate 'chirping' sounds from G5 CPUs
Authored by: vykor on Nov 08, '05 07:38:41AM

Definitely not just a G5 problem. Here on my Powerbook G4, under a certain range of (relatively light, but consistent) CPU load, the machine squeals and chirps. Solutions seem to be:

1). deactivate processor nap via CHUD - the noise instantly goes away
or
2). execute another program that pulls the CPU above this particular load range, or close down programs until load falls below the necessary range.

This is really irksome, and AppleCare doesn't seem to have any idea why. Interesting how nap would affect this noise.
