femp energy manageA comparison of liquid cooling versus air cooling in the Maui High Performance Computing Center showed much less cooling power is required by a water-cooled IT system, compared to the cooling power required by an air-cooled system.

The retrofit installation of the water-cooled system, Riptide, presented a better power usage effectiveness (PUE), typically 15 percent better.

A follow-up report prepared for the Federal Energy Management Program (FEMP) by Lawrence Berkeley National Laboratory determined from the testing, that the water-cooling will save an estimated $200,000 per year in operating costs.
