What are the typical iMac temperatures?

I just upgraded my Mid 2007 iMac to an SSD / HD combo in exchange to the previous HD / DVD drive.

Everything works but before an hour my iMac just turned off like someone would have plugged out the power cable. It was running about an hour before that.

I wonder if there is a problem with the temperatures or with the temperature sensors.

What are the normal temperatures for an iMac?

I currently get these values in iStatPro:

AC/DC Supply 80° C
Airport Card 62° C
Ambient Air 27° C
CPU Heatsink 51° C
GPU Die 68° C
GPU Proximity 64° C
Hard Drive Body 49° C
LCD Proximity 49° C
Misc 53° C
Optical Drive 46° C
WDC WD20EZRX-00DC0B0 (my new HDD) 49° C

Speeds from iStatPro:

CPU Fan: 1199 rpm
Hard Drive 1213rpm
Optical Drive 1000rpm

Btw: I am not having the problem that the fan is always on as described in many other posts. That only seems to happen with the newer iMacs; mine is the first ever built aluminium iMac model.

It would be helpful to know the ambient room temperature.

Running AHT 2 or 3x in a row should detect and report an overheating problem... it might also detect/report what is shutting down your machine.

FWIW except for the GPU area your temps/fans seem to be normal... ( advanced DIY: maybe renewing the thermal paste would help that.

IMHO there's a diminishing point of return where intentionally over-clocking fans at high speeds (over 2k rpm ) only increases the risk of burning out bearings and creating irritating noise.
