I'm going to use some Arctic silver for my T-Bird instead of the original thermal pad that came with my GlobalWin Fop32-1. I've cleaned most of the old thermal pad from the core of the cpu. There are specs left here and there along the edges. I got as much as possible off running a flat tip head of a screwdriver carefully along the edges. Do I need to get rid of it completely or is this acceptbale. I also used some isopropyl alcholol to clean the core. Some of the alcohol also got on a few of the bridges. Is that ok? This is my first time working with a CPU. Are there any other or better ways to clean an AMD cpu? Thanks!
