Two Cool Technologies for Cooling Computers (VIDEO)

IBM shows that hot-water cooling isn’t an oxymoron, and Sandia National Labs builds a better CPU fan.

As computers become more powerful, the cooling systems they rely upon to beat the heat must become more sophisticated. Recent advancements from IBM and Sandia National Laboratories show how far technology has come from the old days, when a single fan was enough to cool down a computer tower.

1. Warm-Water Cooling

Europe’s fastest supercomputer, call SuperMuc, will be one of the first facilities to use a hot-water cooling system. The hot water flowing in the cooling system can reach 113 degrees F.  Built by IBM, the supercomputer and cooling system at the Leibniz Supercomputing Centre in Germany consumes 40 percent less energy than air-cooled facilities, according to the company. IBM explains how the system works in this video.

2. The Sandia Cooler

What’s 10 times smaller, yet 30 times more efficient than a typical CPU cooling fan? The “Sandia Cooler,” developed by the Sandia National Labs. Sandia says its new cooler design combines the functionality of cooling fins with a centrifugal impeller. Spinning at 2,000 RPM just a thousandth of an inch from the CPU, the device is much more effective at eliminating heat and doesn't clog with dust.
