Liquid-Cooled vs. Air-Cooled: A Study in Data Center Energy Use

Research: Liquid Cooling Can Reduce Data Center Energy Use

Data Center Knowledge, October 30, 2013

PALO ALTO, Calif. – Liquid-cooled servers at a data center at the Lawrence Berkeley National Laboratory used less energy in certain circumstances than air-cooled servers on site, a lab researcher said Tuesday at the sixth annual Data Center Efficiency Summit hosted by the Silicon Valley Leadership Group (SVLG).

The tests evaluated at Asetek’s RackCDU low-pressure hot-water CPU and memory cooling technology connected to 38 Cisco servers in a rack at the data center. The servers’ power use was compared with that of more traditional air-cooled servers, said Henry Coles, who works on infrastructure cooling systems at the Lawrence Berkeley lab.
