    I know i know a nother mac temperature thread, But this one is weird. My mac has always been fine, only getting up to about 70*c when encoding. Now it gets past that when doing nothing, and fans going full blast! Tried every mac temp. software. Looked in activity monitor, nothing major running, biggest thing is "activity monitor". I can just have it sitting on my counter, on hard surface, very hot fans full blast. Its a new MacBook White early 2009. Any tips would help, thanks

    Reset SMC and see if that fixes anything. But it's likely that something is running in the background.

    Did you remember to change Activity Monitor to show "All Processes"? These runaway CPU hogs generally are not running as the user.

    You guys are amazing, it is this stupid printer driver. Thanks so much!!!!!!
    IT makes since though, cause its been weird for about over a week, and thats when i got my printer. i use my macbook alot, im just worried that i have been running my mac so hot and fans so long, like burning it out, should i be worried, because my warranty is running out in a week, and if i should be worried i might get applecare.

    How high/low should the temperatures of the CPU and everything else be? What is the limit? My CPU is 71 degrees celsius now. Is it considered hot or normal? :eek:

    It depends on what stuff is running on your computer right now. If you're doing a lot, then 71 is not necessarily bad.

    iTunes playing, Entourage, Adium, WeatherSnitch, Skitch and Safari browsing has me at 50C right now.

    100C is about the limit, although anything over 90C is bad.

    Anything over 60C is considered hot for laptops with decent cooling. Unfortunately, almost all of Apple's recent machines have pretty weak cooling systems, thus it's not uncommon to see temps hit 80C or even 90C. :(

    Same issue but no process found

    Having same issue with cpu temp in mid 60s and fan going constantly. Cant see any process hogging the cpu (showing all processes). Have a MySQL db serving a wiki but this doesn't even make a dent as far as I can see (and nor should it). Otherwise nothing.
    As I write the temp has suddenly, after a half hour, decided to sort itself out. For no apparent reason.

    Spoke too soon. 30 secs after initially posting this the fan ramps up again as does the temp but still no cpu greedy process in sight. Suspect network as reloading this page failed but no other problems noticed. Performance not affected. Odd.
