Antec’s take on the KÜHLER H2O 620:

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.

The Antec KÜHLER H2O 620 seems to take a slightly different approach to its bigger brother. Firstly, it features a slower spinning non PWM fan so we can expect the KÜHLER H2O 620 to be a quieter unit. Size wise, the radiator is 22mm thinner and as such it is lighter and more compact. Only a single fan is included and no software control is provided making ChillControl unique to the bigger KÜHLER H2O 920 unit.

The specifications are not too dissimilar to Corsair’s H50 since they both use Asetek designs. Interestingly, Antec have opted for slightly faster 2000 RPM compared to the Corsair’s 1700 RPM one. The other difference, as previously mentioned, is that Antec have oriented the fan as an exhaust which makes more sense in a regular chassis as it compliments airflow. The unit themselves are very similar, both integrating the reservoir to the 120.1 radiator and combining the pump with the CPU cold plate.
