If you are looking for a fast and easy way to watercool your computer, PureOC says the Antec Kuhler H20 650 is a good way to go. Antec is at it once again developing stronger and more powerful closed loop coolers. Their newest addition to the Kuhler family is the 650, 950 and 1250. The 650 unit is a high performance cooling solution with an integrated large pump built into the cooling fan providing a more efficient and optimized product. With the PWM fan designed to automatically adjust fan speed based on temperature, its directional blade is designed to focus on maximum airflow. It even includes an LED on the block that changes color based on temperature.
