I got a stock heatsink with my p4 3.0 cpu. Now maybe I should just chunk the whole heatsink and buy a "better" one, but it looks good enough, but I don't like the idea of using a parafin wax pad. I'd rather use Artic Silver, my question is, can the pad be removed completely or enough that I can use thermal grease without any problem? I'm not interested in overclocking, i'm more interested in longevitity of the components.
