    I have a macbook 2,1, and I've been having major heat problems. I am currently running safari, quiksilver, and adium, and my CPU temperature has been going between 55 and 60 degrees C. When I plug in my second monitor and play a movie, my temperature goes up to 79 degrees, and sometimes into the 80's. My macbook is on a wooden desk, propped up by two pens at all times, and i am trying smcfancontrol but it won't change my fan speed to what i ask it to. Any help would be appreciated.

    What do you mean it wont change the fan speed? Does the fan speed up at all?

    Easy way to test is to open several YouTube windows at once.

    when i try to change the fan speed using the app smcfancontrol nothing happens. the fan speed does go up by itself based on computer temperature.

    Have you tried dragging it all the way up, so that idling speed is around 6000rpm?

    Take pictures of the Temp etc and go back to Apple with it.

    Is smcfancontrol in the Applications folder? I spent ages trying to work out why it didn't changed the fan speed when it was somewhere else.

    Check activity monitor to make nothing is pushing the cpu usage hight.

    I did a handbrake encode on my macbook (2.0) today, just to see how it went. the temp reached a peak of 83 C. HOT!

    I'll tell you this, it's the LAST time i do a handbrake encode on my macbook. I'm pretty sure it tool like 2 hours! my mac pro does it in like 20-25 minutes, and the processors only get to about 50-55 C.

    neat but

    guys I appreciate the info but what I need to know for this model is temps around 70-75c and fan RPM's into the 6000's NORMAL? If it is, I won't worry. I use a non-fan thermal mat but temps still seem to be high:confused:

    If your fan is always on high and it's still not cooling off appreciably, you might have gunk blocking the output area of your fan.

    After having constant fan noise and overheating issues over the last few months, I finally pulled it apart (Used this guide: http://www.ifixit.com/Guide/Repair/Installing-MacBook-Core-2-Duo-Fan/522/1) and found a thick carpet of almost felt clogged between the fan and the exhaust fins.

    Put it back together and it's like a new computer. It's running 40-50 degrees cooler and the fans are barely working. Just thought I'd throw that out there....
