Right, I've studied some heat transfer as well; I haven't experimented, with things, but I would think that the degree of dust collection over the life of an average computer should be fairly minor. You would still get a lot of heat better heat dissipation compared to just a bare CPU, regardless of the clock speed. I think that it is likely that even significant underclocking may not result in a sufficient reduction in heat output to eliminate the need for a heat sink entirely. At any rate, it seemed like it might be useful for what you were asking about. Aloha, Rob __________________________________________________ Do You Yahoo!?
