I'm not a big fan of the sticky black goop Apple uses for thermal compound. When I swap processors, which is pretty frequent, I always replace it with a better compound. First I remove the black stuff with a plastic (not metal- don't scratch the heatsink or CPU) scraper, scrub it off with acetone (or nail polish remover) and then wipe it with rubbing alcohol. I then apply Arctic Silver Ceramique; it's non- conductive and seems to do a very good job transferring the heat from the CPU t the heatsink. I haven't fried any CPUs yet.
