'Normal' iG5 fan speeds?
-
Mark - 02 June 2007
Since I got my logic board replaced, the fans seem to be running a *lot* of the time.
Average speeds are:
CPU - 4000 to 5000
HD - 2000
System - 2500 to 3000The 'CPU T-Diode' temp is at about 140F

Thanks,

Why, what else could it be?

Presumably nothing given your reply, which I will take
as a "yes".You can see from my guess I thought it might be an iMac.
I wanted to be sure. I don't know much about what Apple
were making before I started using a Mac in early 2006.Cheers,

Yes. iMac G5 (1st Gen). It starts up fairly OK (i.e. quiet), but soon the fans are zooming along full tilt.
Quitting Firefox seemed to quieten them *somewhat* (& it did at least then stop hogging +50% of my CPU!), but they are still buzzing along (they're at the lower end of my original noted 'scores' above. I am *sure* that before all my troubles started I could browse the web & send email *without* any fan interruption...

I'm using an Core Duo iMac, and those speeds are quite a bit higher than mine. During typical usage here the HD fan speed is ~1400, the other two ~800-900. Also, they seem to run all the time. I couldn't say whether that is normal behaviour.
Quite possibly the PPC iMac fans are meant to run faster. I'd be interested to hear what typical fan speeds are on a G5 iMac.
Cheers,
R.
