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,
