'Normal' iG5 fan speeds?

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,

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.

I have a Rev B 2.0 iMac 17", here are my fan speeds:

CPU, 2905 at 70C Hard Drive 2500 at 49C System 2000

This is from iStat Pro.

That does seem high:

1st gen 1.8 20" iG5

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

Using iStat Pro
