The Antec KÜHLER H₂O 620 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 no maintenance. The voltage-controlled 120 mm fan and 3rd generation copper coldplate ensure efficient cooling, while the estimated 50,000 hour pump lifetime means this cooler is even likely to outlast the system it cools. Lastly, easy-bend flexible tubing allows the KÜHLER H₂O 620 to be installed in nearly any orientation. Take your PC's Quiet Computing™ to the next level with liquid cooling performance at a price that rivals aftermarket air coolers.

• Low profile pump ensures exceptional liquid circulation while preserving internal airflow
• Non-corrugated easy-bend tubes for maximum flexibility in radiator positioning
• Intelligent noise / speed-control fan for quiet, efficient cooling
• Latest generation copper cold plate for optimal conduction

As the first reviewer I had to rate this five stars even though I would have docked it one for the instruction manual. That was the only drawback I could find for this product...namely the part about which way the arms on the retaining ring should face when installing the plastic screw retainers. I installed mine the wrong way...fortunately, a butter knife and some firm pressure popped them out, and they went back in the other way and installation went well. This might not be an overclocker''s tool, but it is a solid introduction to liquid cooling. It mounts easily in a case in place of an existing 120mm fan, it hooks into the CPU header for power, and with my existing Aerocool FP-01 fan controller, works wonderfully. Additionally the solid copper coldplate has a little overlap over the CPU, which means I have a great place to install a thermistor for accurate thermal readings. I may replace it if I can afford to upgrade to an EK modular cooling kit, but I would see it sold used to another buyer because it will do much good...it keeps a hot CPU cool and with far less noise!
