Next Generation Maximum Performance Liquid CPU Cooling System

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.

High Cooling; Double Your CPU Performance

The 120mm Pulse Width Modulation (PWM) fan are fused with directional blades that channel air through the radiator for optimal cooling. The Kuhler H2O 650 comes pre-filled; and never needs refilling or priming. The easy-bend tubes allow for maximum flexibility in radiator positioning and are sealed tight shut to avoid an leakage.

Temperature Controlled Led

RGB LED illuminates your case and changes color to indicate CPU temperature. During extensive and high demand gaming; no need to pause or exit; monitoring CPU temperature is made easy with the temperature controlled LED. Take a quick glance and carry on dominating in the game!

Universal Compatibility

The Kuhler H2O 650 includes a newly designed universal mounting bracket that works with either an Intel or AMD CPU.
