Since I got my MacBook, I have been plagued with random Kernel Panics that, at first I though were all related to specific software. But as time went on, seemed more and more random. Usually, they happened at the end of the day and didn't seem to be related to a particular piece of software.
After a while, I was suspecting a problem with heat buildup. I had noticed that, after a day of usage at the office, my MPB would be really warm to the touch when I packed it to go home. After installing iStat nano, I observed that the temperature would get all the way to 70C and yet, the fan would remain steady at 2000 rmp.
I had observed that the fan would speed-up when I was doing something CPU intensive but the speed didn't seem to be related to the CPU temperature, only CPU usage. That seemed odd to me as I use the computer all day and the CPU rarely spikes very long. So the heat kept building up and I kept getting Kernel Panics.
3 weeks ago, I found and installed Fan Control. A little control panel utility that monitors the CPU temperature and changes the minimum fan speed for me as the temperature changes throughout the day.
My MPB now remains under 60C all day and I haven't had an unexplained kernel panic since.
