A better heat exchanger for that hot processor, The Sandia cooler

CNET reports on what they call a fanless heat exchanger.

Fanless heat sink design promises cooler, quieter CPUs

by Rich Brown

As a product category, CPU cooling hardware tends to offer few worthwhile developments, but a new heat sink concept from Sandia National Laboratories seems to offer tremendous promise for computers, as well as cooling appliances. Designed by researcher Jeffrey Koplow, the new "Sandia Cooler" does away with a separate fan component, and instead relies on the heat sink itself to disperse heated air.
