A new processor, as was already mentioned, usually has a self adhesive thermal conductive sticker with it. So usually you only need to use the paste if you change processors. If you buy the processor kits that come with the heatsink, then you'll probably get the self adhesive sticky thing. Ask before buying if it has this. If you do need to use paste, not a lot of the stuff is required. It's also expensive, so might be better to just buy the kits with the cpu and heatsink. -- Doug
