The KUHLER H2O 650 Closed Loop All-in-One Liquid CPU Cooler from Antec delivers high-performance liquid cooling for your central processing unit (CPU) in a quick, easy-to-install package. Unlike traditional liquid cooling systems, this self-contained unit comes pre-filled and requires no maintenance. The extra large pump circulates coolant through optimized water channels, while easy-bend flexible tubing allows the KUHLER H2O 650 to be installed in nearly any orientation.
In addition to easy installation, a powerful Pulse Width Modulation (PWM) fan pushes air through directional blades and channels it through the radiator for optimal cooling. Included in the box is an air duct that reduces static pressure, which allows air to flow out of the case efficiently. The integrated firmware automatically adjusts fan speed and changes the RGB LED indicator based on temperature.
