I use this dashboard widget iStats nano, which has always shown temperatures that seem off. Incoming air always reports +100 F temperature even when room temp fluxs between 55 & 90 F... I assume that the heat sensor is inside the iMac :D but is it really measuring incoming air temps so far inside that the air temp is already normalized?

My machine pretty much reports this always, no matter what the environment and usage load... Is this normal?

CPU 160
GPU 150
HD 120
AIR 100

Edit: (I can't believe I forgot) 20" iMac G5 w/ iSight

Which revision iMac G5 do you have, and what size is it?

The one in my sig usually measures:
CPU - 160 F
HDD - 130 F

I don't know where the other temps are coming from. When I downloaded iStat nano, those were the only two temperatures it gave me.

wow, those numbers seem a smidge high. especially the CPU... i was worried about my CPU over heating once so i told Apple and the dude told me about 150˚ is about all. are u sure ur system still works? i'd report this to Apple.

Aaarrgh, why can't everyone use Celsius so I can understand your numbers? :p

I use X-Resource Graph for my stats, which usually reports my 20" iMac CPU somewhere around 62-66C (approx 143-151 F) and the 17" iMac around 68-73C (approx 154-163 F). Both are 2.0GHz revision B iMacs.

Gets about 74C when you push my iMac (no not literally off the desk) but it has shut down on me once during a Halo session :eek:

Mem controller ambient = 62c
Optical drive = 39c
Mem controller = 75c

CPU Fan = ~1400 rpm
HD = ~1900 rpm
Optical drive = ~1600 rpm

Yes please use metric units....:D

It is STANDARD for my CPU to idle around 170 F....and when it's running under a full load, it consistently approaches 200.

It makes me so uncomfortable (considering I had a rev.A that fried) that I always run the system with the processor on the reduced setting.

Grrr.

I find Automatic just fine. It starts to get noisy around 50-60% usage.

200 F seems to be too high. I surprised your computer hasn't shut off by that point. Have you tried another temp monitor to make sure it is accurate?
