Another way to control CPU napping
Authored by: Unsoluble on Nov 15, '05 05:09:18PM

Hmm. Every time this chirping thing comes up, it's reported as being associated with high CPU activity, or at least as a sporadic sort of thing...

Mine's quite the opposite, though: I've got a dual 2.0 G5 from last summer, and if I don't disable napping I get a very regular, very audible chirp roughly every second. Chirp, chirp, chirp, chirp, ad nauseum. Can't stand it, so I turn napping off. But if it was only periodic, I might be able to handle it.

Nobody else has just the regular chirp?

My dual G5 tower has both the regular chirping, and irregular chirping during activity. Until I read the threads here I always assumed the regular chirping was coming from the fan, but disabling CPU napping makes both kinds of chirping go away.

I find this whole issue rather surreal... I mean, I understand how a fan or a hard drive could chirp, but the CPU...? I'd really like to understand this.

Yes, the only extra noise I get is a fairly quiet beep once a second when activity is low, and is fixed by unchecking "allow nap" in processor prefs (part of CHUD tools).
