Cooler Master VHC-L61-U1 VIVA - ventilátor aktivní s velkým pasivním chladičem a HeatPipe pro grafic

Silent cooling for the graphics card that uses heatpipe technology.Cooler consists of two aluminum plates connected heatpipe tube, which is Furthermore, the lower portion, attached to the core graphics card, cooled přídavým fan.The radiator is designed for graphics card nVidia and ATI.Power supply fan is implemented through the standard 3-pin connector to the motherboard.

Heatpipe technology is based on the closed-tube, where its "hot" end of the liquid with a low boiling point, which is beginning to evaporate by heating and gas form increases the "cold" end where kondenzuje and after the walls of the tube is returned in liquid form back .When heating the liquid is waste heat from the chip used to change the form and then in the form of hot steam goes to the other end, which must be cooled to a temperature at which steam zkondenzuje.Contrary to conventional convection heatpipe technology therefore offers more efficient heat transfer, but only if a sufficient temperature difference between the two ends of the tube and its correct orientation.
