I have an AMD Athlon 64 3700+ San Diego. I just recently appiled Arctic Silver 5 to the stock heatsink. Cleaned it up and everything before I applied using 91% isopropyl alc. My Idle temp. is around the low 40's and my load temps are around the low 50's, close to 60C if I OC from 2.4Ghz to 2.6GHz+... Is is supposed to be running this hot? I still haven't broken in the initial 200 hours that is needed for Arctic Silver 5 to work at it's full potential. Could that be the problem?
