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.

Sandia’s “Cooler” technology offers fundamental breakthrough in heat transfer for microelectronics, other cooling applications
Sandia’s Jeff Koplow makes an adjustment to an earlier prototype of his Air Bearing Heat Exchanger invention. The technology, as known as the “Sandia Cooler,” will significantly reduce the energy needed to cool the processor chips in data centers and large-scale computing environments.(Photo by Dino Vournas) Click on the thumbnail for a high-resolution image.
Licensing opportunities now available
LIVERMORE, Calif. — Sandia National Laboratories has developed a new technology with the potential to dramatically alter the air-cooling landscape in computing and microelectronics, and lab officials are now seeking licensees in the electronics chip cooling field to license and commercialize the device.
The “Sandia Cooler,” also known as the “Air Bearing Heat Exchanger,” is a novel, proprietary air-cooling invention developed by Sandia researcher Jeff Koplow, who was recently selected by the National Academy of Engineering (NAE) to take part in the NAE’s 17th annual U.S. Frontiers of Engineering symposium.
