iMac Temperatures

What kind of temperatures are the newer Intel iMac's running? I did notice that mine got up to 126 degrees F when I was downloading a movie, listening to a podcast, and browsing the internet. (Man, these Macs are sweet!)
On average, it seems to run less than 100 degrees F when doing simple applications.

Same question plus....

What is a "GPU"....the one that gets hottest?

GPU is Graphical Processing Unit, the CPU for your video card.

I think you are probably quite safe. My GPU gets up to 73 C when running hard, and that is about 163 F!

Around 40C on average.

FWIW.....

Hottest temps I'm seeing top-to-bottom (F) are 107; 129; 80; 96; 104.

At those temps, fan speeds remain about same as at start-up (800; 1400; 800) which leads me to believe such temps are of little concern. Don't know at what temps fan speeds would begin adjusting upwards.
