I hate to horn in on this Tom, but you made it too interesting. ;) I would like to add that pads are one shots. They are designed for one mounting and one only; after that their efficiency is shot. Theoretically pads are supposed to have an advantage over grease, but only if you never upgrade. (i.e., remove the heat sink and put it back with the same pad) Also much of the "efficiency advantage" is lost comparatively speaking if you use a superior heat compound like Arctic Silver 3, which is according to test results the best stuff on the market right now. I would also like to add that instead of alchohol, if you want to remove hardened heat grease a better choice for softening and removal is odorless mineral spirits with Q-tips. I found it works better here, probably because heat compound and mineral spirits are both petroleum products. One more suggestion I have, and I think it's the most important one, wear your static wrist band secured to a valid earth ground while you are inside the machine, so that you will keep your computer equipment in mint condition.
