Kuhler H2O 650

Next-generation Maximum Performance Liquid CPU Cooling System

With a perfect combination of superior cooling performance and aesthetic yet practical design, the Antec Kuhler H2O 650 is engineered to stand out from today's liquid cooling market.

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 to produce voluminous airflow for optimal cooling performance. 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.

The built-in RGB LED not only illuminates your case but also can change color to indicate CPU temperature, thus CPU temperature monitoring is easier than ever before.

Plus, the Antec Kuhler H2O 650 is easy to install, and requires zero maintenance.

general information

High Cooling, Double Your CPU Performance

The 120mm Pulse Width Modulation (PWM) fan is 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.
