I recently bought a HSF (gotta return it and buy a better one) and some thermal grease. A lot of my research only seems to explain how to apply this grease to Slot 1 CPUs. I have an AMD 1.2 GHz Slot A, I'm not exactly sure where to put the grease. Another question is, is all the grease the same? and if not, how much different can each be? Thanks.
