H2Ceramic cooling
H2Ceramic cooling (also called H2C or Hot-to-Cold) is a computer cooling product offered as an option in Dell's XPS gaming systems, advertised specifically as facilitating CPU overclocking. H2C is a two-stage Liquid/Thermoelectric (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.
The components are delivered as a single unit designed to last a minimum of 5 years without service or liquid refilling. The XPS 710 H2C and Dell XPS 720 H2C featured a design where all components were mounted in a single plastic chassis and which only cooled the CPU. This design only matched motherboards with a very specific CPU socket location and was later replaced by a new and more flexible design featuring a separate pump unit which made it much easier to fit a broader range of motherboards with different CPU socket locations. The new design allowed the unit to cool the motherboard chipset as well.
