Submission + - Defense Department Using Hot Water to Keep Servers Cool (datacenterknowledge.com)
1sockchuck writes: The U.S. Department of Defense will soon begin cooling its servers with hot water, converting one of its data centers to use a liquid cooling system from Asetek. While most air cooling systems use chilled water at temperatures as low as 45 degrees,it's possible to use higher water temperatures in tightly-controlled environments that focus the cooling as close as possible to the heat-generating components (see other examples of this technique). Asetek has been a leading supplier of liquid cooling solutions for high-performance gaming PCs and workstations, and is now expanding into the data center market.
