Features & Specifications

Antec’s take on the KÜHLER H2O 920:

The Antec KÜHLER H2O 920 provides maximum-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 zero maintenance. The dual 120 mm Pulse Width Modulation (PWM) fans and 3rd generation copper coldplate ensure quiet, efficient cooling, while the 49 mm thick radiator is equipped to handle the highest performing CPUs on the market. Lastly, the included software helps you monitor and control the KÜHLER H2O 920's performance and allows you to customize its stylish RGB LED. Designed to unlock the maximum potential of your CPU, the Antec KÜHLER H2O 920 delivers exceptional cooling when you need it the most.

From the features and specifications, Antec seem to have outright performance in mind with less thought on noise. Despite the PWM capability and the marketing to suggest quiet operation, it is clear that the best performance will be with the two fans operating at the maximum speed of 2400RPM which will be by no means quiet. To achieve the best performance, Antec have opted for a 49mm think radiator for a higher surface area compared to typical single radiator designs which usually come at 27mm thick, as is the case for the KÜHLER H2O 620. Like other ALC units, the KÜHLER H2O 920 is composed of the same components, a 120.1 radiator with integrated reservoir and 2 hose pipes connected to the pump and cold plate combined module. Unique to the Antec KÜHLER H2O 920 is the ChillControl software that allows users to control the fan speed and the cooler’s RGB lighting.

Surprisingly, the cooler weighs in at a hefty 1.1kg, comparable to even the largest air coolers on the market. However, this weight does not hang off the motherboard but rather the case itself. Since the cooler is based off a similar Asetek design employed by Corsair, we can discuss some of the differences. The key difference without having a H70 to compare against is the Antec have positioned the fans as exhausts rather than intakes. This is a more intuitive design to compliment chassis airflow but we will have a look if changing the fan orientation makes any difference later on.
