Fry bacon, not processors; AMD processor and thermal paste
Couldn't get my AMD K6-II machine to compile kernel 2.4.18, it crapped out in random places. Many googles later this site introduced me to the wonder that is thermal paste/ heatsink gel. Now it blasts through that sucker. What struck me as funny was that there was no residue of any similar paste in the area before.
Here's what I did for those stumbling upon this post in a hot daze:
Blasted MB with canned air to rid of dust.
Took off heat sink
Cleaned heatsink with nail polish remover
Lightly used canned air on top of processor (careful - too close and the cold liquid can condense on the surface)
Applied some paste to the top of the processor - a few small dabs and lines
Rubbed heatsink around on top of processor - until I could hear/feel metal on metal contact (the paste is supposed to fill in the gaps between the heatsink and the processor - but the thinner the layer the better heat transfer)
Closed up computer
