Researchers at Purdue University claim to have developed a new kind of cooling technology. Tannaz Harirchia and Suresh Garimella are using boiling liquid inside microchannels on specially fabricated chips to more efficiently cool components.

Fluids do not behave in the same way in microchannels as they do elsewhere, allowing for increased heat exchange. “Allowing a liquid to boil in cooling systems dramatically increases how much heat can be removed, compared to simply heating a liquid to below its boiling point," the researchers wrote. The device constructed at Purdue is basically a small one inch square heatsink. After liquid has boiled off in the microchannels, a small compressor disperses the heat, returning it to a liquid.

The technology has possible applications in both PC and automotive cooling. PCs are relying on numerous fans, or bulky water block cooling. Similarly, cars use both air and water cooling to remain in working order. Both these areas could see advancement if this microchannel cooling technology takes off.

Scythe is a newcomer to the U.S. cooling market, and is trying to establish itself as the go-to company for monstrous heatsinks that—like Zalman’s—offer quiet cooling. We reviewed the company’s Ninja Plus cooler in July, and were impressed by its silent operation. The Mine runs just as quiet, but suffers several major flaws.
