The Antec KUHLER H2O 620 delivers high-performance liquid cooling for your CPU in a quick, easy-to-install package. Unlike traditional liquid cooling systems, this self-contained unit comes prefilled and requires no maintenance. The voltage-controlled 120 mm fan and 3rd generation copper coldplate ensure efficient cooling, while the estimated 50,000 hour pump lifetime means this cooler is even likely to outlast the system it cools. Lastly, easy-bend flexible tubing allows the KUHLER H2O 620 to be installed in nearly any orientation. Take your PC's Quiet Computing to the next level with liquid cooling performance at a price that rivals aftermarket air coolers.
