Antec KUHLER H2O 650 Water/Liquid CPU Cooler

The Antec Kuhler H2O 650 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 zero maintenance.

The extra large pump circulates coolant through optimized water channels, while easy-bend flexible tubing allows it to be installed in nearly any orientation. The Kuhler H2O 650 comes with a 120mm fan.

The fan’s motor hubs also work as the coolant pumps, and the flow of the coolant is in direct proportion to the fan speed. So a higher fan speed directly translates to a higher coolant flow.
