I've been using Arctic Silver for years, and it's the only thermal compound I use. Whether I'm building a new system, or upgrading an old one, Arctic Silver has never let me down. My CPU temperatures are always a few degrees cooler when replacing the standard thermal paste or thermal pads that most PC and CPU manufacturers use. I even sometimes use it on my GPU cards too to keep them cool. I highly recommend it. If you're a novice on applying thermal compound, I highly recommend you go to Arctic Silver's website and read the excellent instructions on doing it correctly.
