Researchers further pump-less liquid cooling

Slashdot tipped me off to this interesting story on a new liquid cooling system designed for PC processors. What's unique about this liquid cooling solution is that it's a completely closed system with no external pump; the liquid's flow is sustained by heat generated by the processor. Researchers claim that their new design, which uses tiny "microchannels" only three times the width of a human hair, is capable of removing almost six times more heat than other pump-less liquid coolers. However, there's no word yet on how the new system stacks up against liquid-based coolers with external mechanical pumps.
