Thanks guys, but I should have mentioned that I'm approaching my first build from a total noob perspective. I have all the bits, with some en route, I'm expecting to start next weekend. For fitting my artic cooler freezer 7 (to my new conroe), I understand that I have to remove the existing paste from the ACF7 and "lap" the surface, having first marked it with a permanent marker to show the flatness.
Assuming that I use standard paper, what would you recommend? What should I be looking for? Thanks again.
