<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.>
Heat sink is OK. Since a heat sink does not make any noise, I am willing to put up with the largest heat sink in the world. My key concern is, how much a fancy heat sink will lose its heat dissipation efficiency over time. But the Zalman Copper CPU Cooler does seem to be a very interesting system. Do you know any local store(s) may carry it?
