I have a stock heatsink that came with my Rig from MWARE and it's seems like it's got a ton of scratches on on side where it was making contact with my cpu core. I tried GooGone and Isopropyl alcohol and no luck in getting rid of it. I have o/c to 1.2GHz (12X100) with idle temps around 44C and full load temps slightly higher. This stock heatsink is made by AVC w/ about 5000rpm's. I have Artic Silver II on it now but the temperature has increase over the stock thermal paste that was on there. How significant could this be?
