I'm staring at my hsf and cpu inside the plastic right now. Other parts aren't coming for two more days. I do notice that intel's hsf is real beefy compared to the last stock one I had from them (celery 2.0). It's got a copper core and what looks like 3 pieces of a metallic colored thermal compound. How is this stuff? I'm probably just going to wipe it off and go straight to as5 that I have lying around. But I'm really curious how well their stock interfacing material does. Anyone compared?
