     Antec launches the KÜHLER H²O 920

    Antec has launched a new all-in-one watercooling solution, the KÜHLER H²O 920. As with the 620 version, the manufacture of this unit is outsourced to Asetec and it is in fact a version of the 570LC that is also used by Corsair with its H70. The radiator is 49mm thick compared to 27mm on the 620 and there are two 120mm fans instead of just one.



    On the Antec solution however the two 120mm fans run at between 700 and 2400 rpm, while on the Corsair cooler they run at between 1600 and 2000 rpm. It should however be noted that on the Corsair side, the figures given correspond to the maximum running speed of the fans, with or without an adaptor designed to reduce their running speed. You can of course regulate them using a fan speed controller or more simply via the motherboard.


    The KÜHLER H²O 920 however uses the Liquid Temperature Fan Control technology announced by Asetek this week. The principle is simple, with the KÜHLER varying the fan speed according to the temperature of the cooling liquid, which is measured by a sensor in the pump.

    Asetek is highlighting the fact that because of the higher inertia of a watercooling system, the variations in fan speed are more progressive than with a standard PWM motherboard regulation system. This is true in comparison to a system in which fan speed regulation is based only on CPU load, but on many motherboards it’s possible to link fan speed regulation to the temperature of the processor and they may therefore also profit from the inertia of watercooling.

    The 620 version of the Antec KÜHLER H²O already used LTFC technology but in its automatic version. The KÜHLER H²O 920 is linked to the PC by USB, which means Asetek’s ChillControl V application can give feedback on the cooling liquid temperature, the fan and pump speed. You can also customize fan speed regulation and the colour of the RGB LED included in the pump.


    The Antec KÜHLER H²O 920 should be available over the coming weeks, with the first etailers quoting it at €119.90, a €50 increase on the 620 version.
