Thermaltake Extreme Spirit II

Universal cooler designed for Northbridge chipsets and processors, VGA Heatpipe technology is equipped to guarantee a high quality heat dissipation and active fan size 40 x 40 mm with a speed of 4500 revolutions per minute. It is located between the cooling fins, which are made of copper. Base to ensure contact with the chipset is made up of copper. The whole cooler is very quiet (19 dBA) and its service life reaches 30,000 hours.
Heatpipe technology is based on the closed tube, where the "hot" end is a liquid with low boiling point, which is beginning to evaporate, and heating the gas phase rises to a "cold" end where it condenses and the walls of the tube is returned back into liquid form . When heating liquids, waste heat from the chip is used to change state and then in the form of hot steam goes to the opposite end, which must be cooled to a temperature at which vapor condenses.Compared to the classical convention Heatpipe technology has thus increased the efficiency of heat transfer, but only if a sufficient temperature difference between the two ends of the tube and its correct orientation.
