THE KUHLER H2O 920

The bundled 120mm PWM fans can reach speeds of up to 2400RPM and produce up to 110CFM of airflow at 43dBA of noise.

The Kuhler H2O 920 comes pre-assembled with the large tubes attached to the thick aluminum radiator on one side and the pump/waterblock module on the other.

The double radiator of the Kuhler H2O 920 version measures 151mm in height, 120mm in width and 49mm in depth.

Compared to the unit i tested over a year ago the radiator fins of this version are much better although far from perfect.

There are 4 holes placed on the four corners on each side to mount the bundled 120mm fans, however you can also mount two 140mm fans as long as they come with 120mm holes.

The 330mm long tubings of the Kuhler H2O 920 should make installation a lot easier to complete.

Just like with similar solutions we see that the pump is attached on the base of the cooler.

The tubings feature a 90 degree swivel to further simplify the mounting procedure.

In order to use the Kuhler H2O 920 you will first need to plug the USB cable and then the 3pin fan cable onto your mainboard. If you decide on using the provided software you will also need to plug both 120mm PWM fans to the 4pin cables.

The copper base of the unit has quite a few visible machine marks and comes with a thin pre-applied layer of thermal conductive material.

With both fans mounted the radiator of the Kuhler H20 920 now measures 99mm in depth so prior to making the purchase make sure it fits inside your tower.

Remember that if your tower comes with a top exhaust fan (or fans) then you should have both fans facing inwards so that they can push cool air from the outside to the radiator and thus improve the efficiency of the unit.

However if your tower lacks a top exhaust fan (or fans) then you should have both fans facing outwards. We tested both configurations to see what performance you can expect with each.
