Lapped the CPU/Cooler?? You'd be surprised how uneven the AMD chips are. (forgot what they call the metal piece) You can build a liquid setup for pretty cheap.
http://www.petrastechshop.com/watercooling.html . D-Tek Fusion blocks and Swiftech pump with XSPC pump top and Res. That pump top helps the flow a LOT.
But come to think of it, 120* F (F?) is only 48.8888888888888888888* c so that's still pretty dam good! And the stock AMD coolers actually work pretty frickin good! Juice it up, run a burn test on it and see what it does. Up the multiplier until it becomes unstable, then juice up the voltage if you need to. You can find the ceiling of the stock voltage real easy. I think i got my stock Phenom II cooler to around 3.4 gigs before I got rid of the dust pumps and went to a liquid setup.
