I just boosted it back to normal now that I've cleaned the system and replaced the heatsink/fan and thermal compund.

temp is now stable at 46 degrees Celsius

I even went to the AMD support forums and they said to replace the heatsink, fan and thermal compund. So I spent 25 bucks on a high-flow vantec combo. I was going to buy the arctic silver, but unless this compund sucks ass, I don't care.
