    Ok so I had my computer idling and noticed that the fans sped up to full blast, so naturally I tried to figure out what was causing it to heat up. I quit pretty much every app I had running, no diff. I unplugged my iPhone, no diff. Even shutdown the computer, fans went right back up as soon as I loaded up OS X. So I looked at SMC Fancontrol (which I never really even use) and the temp was at 88 C!!

    What's going on here? I have nothing open, completely turned off the computer and rebooted it to make sure that nothing running would be causing it, and it's STILL running hot as hell! Is there anything I can do to see what's causing it to run so damn hot? I really don't wanna put a crap-load of wear on my fans and CPU here.

    I'm using a 2.2 ghz SantaRosa MBP running the latest version of Snow Leopard.

    Quick update, I just opened up activity monitor and noticed that under the CPU tab, the cpu usages are as follows (average):

    % user - 13.45
    % System - 39.36
    % Idle - 47.72

    They change slightly but that's the average set of numbers.. Is something hidden running in the background and causing the cpu to constantly run? The funny thing is, when I look at the list of open applications and processes, pretty much everything is at 0% usage, so I don't know where this 39% system is coming from..

    I need help, what do I do?

    Could be a bug from recent update interacting with your hardware incorrectly.

    I've also got this issue, my temperature is very hot and my fans are really up there, they're currently at 3680 rpm and not 3608 rpm (see picture). I also keep having to turn my Airport off and on in order to access the internet, sometimes Safari will not load pages at all, and yet my Airport says I have full signal. Any suggestions?

    Ok so I didn't realize this, but in activity monitor, I didn't have "All processes" showing, just "My processes" which didn't show the culprit. The culprit was something Lexmark related for a printer driver I haven't used in months, so I don't know why it all of a sudden now wanted to run.

    So I killed the process and uninstalled all lexmark drivers and bam, seems good now.

    Thanks for the help guys.

    Wow, that one I don't have a clue, that's some pretty high temps along with a few other strange issues...

    Might be a bad suggestion but try doing what I did and go to activity monitor and click "All processes" and see if there's any item(s) eating up lots of %CPU. If so, those are causing the heat, and maybe as a result, the heat negatively affects how your computer is performing ect.

    Lemmie know if that helps.
