The purpose of this white paper is to provide information about current alternative technologies available for data center equipment cooling. With the proliferation of data centers and the ever increasing density of “processors” or “chips,” traditional computer room air conditioning systems (CRAC) will not be able to adequately and cost-effectively handle future cooling requirements. Therefore, liquid cooling is becoming an attractive alternative to traditional CRACs. The three liquid cooling technologies evaluated in this paper are two-phase immersion cooling, liquid to the chip, and single-phase immersion cooling
