I heard numerous suggestions saying that removing the rubber at the bottom of the heatsink will help lower temp. Initially I didn't do that. Although the HSF(FOP32) is already doing a good job with the rubber on (8c more than system temp.), I still decided to give it a try. I scratched off the rubber and applied thermal paste. After remounting the HSF, instead of lowering the cpu temp, it increased by 2-3c. Now I hope I hadn't done that...
