As we have observed from the appearance of the cooler and some of the emblems found on the radiator and back plates, this is a re-branded Asetek unit. The product is a good solution for people that want to experiment with water cooling, with no efforts at all, because it comes assembled and requires zero maintenance during its lifetime. However, to avoid damages to the pump, it is recommended to connect the cooler to a non-regulated 3-pin fan connector on the motherboard.

In terms of performance, the new water cooler from Antec offers decent performance, and gets close to the high end air coolers. When the CPU was overclocked to 4GHz, the temperature difference between the Noctua NH-U12P SE2 and the Antec water cooler shrunk some more.

The Antec Kühler H2O 620 CPU cooler can be found in shops for about 55 EUR, less than the solutions from CoolIT (like the ECO or the much more expensive Vantage), but it is close to the Corsair H50, which is also a good all-in-one water cooler.

I would like to thank again to Antec for offering me this sample for review!
