    Hi. As you can see by my signature, I'm using the high end 24" iMac. I bought this past September and haven't had any problems as far as I can tell, but now I'm not so sure. I have iStat Pro for my dashboard and it typically shows all of the parts running at between 120-165 degrees fahrenheit. Is this hot??? I'm not sure if the stats are accurate, but I went up and felt around on the back and sides and the computer felt pretty warm. I can also hear a humming noise which I'm sure is just the HD and the fans, but it may be significant. I'm just concerned because these temperatures show consistently even when I'm not running any intense programs.


    Can someone please explain to me what the normal operating temperatures are and whether or not I should be concerned. Any help would be appreciated. I do have AppleCare, btw. :)

    120-165 (48-74 Celsius) is normal for your CPU at standard settings of the fans, although the 74C on the CPU would only be acceptable under high load.
    As for other parts, depends... for example my hdd temp is around 55C.
    I don't allow temperatures above 58 Celsius on my CPU (controlled via smcFanControl) with average around 45C. On occasion the temperature does get closer to 60 e.g. when encoding videos, but I've set a cooldown profile in smcFanControl which cools the sucker down rather quickly. My standard profile is 250rpm faster than apple settings, the computer remains silent and runs much cooler.

    I was going to start a new thread to ask this but as you mentioned it...

    I have a mac book pro and am going to get an iMac when they finially get round to realising the new specs.

    Does smcFanControl work on the IMac and is it nessessery. I know it is on my MBP as it does get a little toasty at times :p

    personally id be worried but I dont have the lauminum I have the white one and it rarely get above 110F and thats only when Im exporting with FCE
    but to solve this problem just download smcfancontrol thats what i use when I feel its too hot and you can manually control the speed of the fans but beware it will make your computer louder

    All your temperatures are close to my iMac 24" . Mine is the Rev. A, first Aluminum version. Everything runs just fine.

    will using smcfanconftrol mess up your imac?
    i downloaded the software and it works great. my imac gets really hot when I game but it is otherwise it is just warm.

    someone recommended the imacfancontrol.

    but it seems to be too actively regulating the fan imo so I haven't tried it.

    Can someone with experience of using both (smc or imacfan) post some comments? Thanks!
