Run running IMAC 27 inch with 24 inch monitor through thunderbolt. No gaming, these are temps just reading email....surfing web and looking at iphoto. These temps are Fahrenheit

HD = 117
cpu = 108
ambient = 76
gpu diode = 176
gpu heatsink = 164
mem controller = 122
optical drive 115
power supply = 130
 
Your Mac is not overheating. Macs are designed to automatically shut down to prevent damage if they truly overheat (around 100C/212F - 105C/221F, depending on your processor). Your temps are well within the normal operating range, and are perfectly normal.
 
yeah, dunno WTF the fuss is all about. looks totally normal.

I made this thread which a few people have listed temperatures in Celsius (you can change it to that setting in iStat Nano with the "i" at the top right, for comparison). As others have said, hot temps are fine.
 
176 Fahrenheit in the GPU for just reading is a bit hot, specially if your iMac uptime is less than a couple of days.

Take a look at this thread, I think that it will help you.
 
Badger...your GPU Diode says 139. Mine is consistently pegged at 175?? I guess its the extra monitor?

Thanks for the feedback guys.

I had just restarted, and Im running dual monitors as well, which Im sure has nothing to do with anything.

I dunno why anyone would eff around with your fans on a brand new machine.

FWIW Im in central CA, plenty of +100º days here and my office gets full sun from about noon on. Been fine for almost 4 years. My G5 tower that was in here before easily added +10-15º. heat box.

I dunno too. Why someone would like to keep an iMac cool? Let it fry.

Who says its not "cool" enough already?

Can you tell me what the optimum temps *should* be?

Are you an Apple engineer that worked on the iMac and was tasked with getting it to run cool? Or are you just smarter than the person they hired for that?
 
Did you read the thread?

JimMacFan said that is just reading emails and the GPU is 176F. Your GPU is at 137. Your GPU temp is fine, but I don't think that 176F for just reading email is fine.

This is a problem? Probably not. But can be a problem if he runs any app that uses the GPU, going to a higher temp.
 
If any of those sites have Flash, that alone can account for the temps. Add emails and iPhoto to the mix and the temps are quite normal.

Ok, no problem.

You do what you find better for yourself.

I prefer keeping my GPU around 140-F doing the same thing.

Macs do a fine job of managing temps, without user intervention needed. You can do whatever you like, of course, but it's misleading to tell others there's something wrong with normal operating temperatures. There are enough people already who are needlessly obsessed with temps.
