'Normal' iG5 fan speeds?

Message #1 - Posted 2007/06/02 - Mark

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 3000

The 'CPU T-Diode' temp is at about 140F

What is an iG5, please? An iMac G5?

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,

R.

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,

That does seem high:

1st gen 1.8 20" iG5

CPU 140F 1531rpm
HD 100F 1800rpm
System 1240rpm

Using iStat Pro

With or without religion,
you would have good people doing good things
and evil people doing evil things.
But for good people to do evil things, that takes religion.
