H2Ceramic cooling

H₂Ceramic cooling (also called H₂C or Hot-to-Cold) is a computer cooling product offered as an option in Dells XPS gaming systems, advertised specifically as facilitating CPU overclocking. H₂C is a two-stage Liquid/TEC hybrid cooling system that combines a liquid-to-air heat exchanger (much like a liquid radiator), a thermoelectric fluid chiller, and control circuitry to optimize CPU cooling with minimal power.

According to Dell, the cooling efficiency of H₂C contributes to PC systems that are cooler in over-clocked mode and potentially quieter in normal operating mode. By cooling the CPU below what is possible with traditional forced-air convection or water cooling systems, but preventing the temperature from falling below ambient room temperature, H₂C is advertised as extending CPU life while eliminating the risk of humidity condensation.
