Keeping cpu temps under control

I've been having a few panics lately and from what I can figure out it is being caused by my cpu overheating. It just started after I began watching rather large MKV videos, which I know can be taxing on a cpu.


I've installed Temperature Monitor, which I know is not 100% accurate, but my temp jumps from 42ºC to 55+ºC in a matter of minutes while watching the large files. The problem is that my fans don't kick into a higher speed to compensate. They do when I'm in windows 7, but nothing happens on the mac side.


I have nullcpupowermanagement.kext installed, and I have c-state and p-states enabled in chameleon (though I'm pretty foggy about what they actually do), but nothing is working. My fans always run at a low speed.


I'm running 10.8.2, with a Q8400cpu in a GA-EP45T-UD3LR mobo.


Any suggestions?
