You need a better heatsink and fan for your CPU.  If you're idle temp is 
45, that's too high.  By using powerd, so it's 800MHz, and being idle 
I'm at around 26C, presumably.  It peaks at 45C on parallel builds.  In 
the meantime, you can set the maximum cpu speed, which I recommend 
powerd for.

Here's a tip when shopping, get a big beefy heatsink with a standard fan 
size, and replace the fan with something beefier.  Either that or water 
cooling.
