THE KUHLER H2O 650

The basic design of the latest KUHLER H2O 650 follows the typical one we've seen with many similar AIO solutions in the past.

Compared to the KUHLER H2O 620 the pump of the 650 model is larger and is mounted in front of the 120mm fan that can reach speeds of up to 2400RPM.

This means that the liquid has less distance to travel between the pump and the radiator something that should have a minor positive impact in performance.

Compared to normal fans the directional blades of the built-in fan push more air through the radiator.

The radiator used is a 159mm in length, 120mm in width and 27mm thick.

Unlike many other AIO Liquid CPU Coolers the radiator fins of the KUHLER H2O 650 are very good in quality.

The tubes are 300mm long so you shouldn't have any problems installing the unit.

The 120mm fan along with the pump and the LED over the waterblock are powered by a single 3pin fan connector.

Once turned on the waterblock gets illuminated with various colors according to the temperature of the base.

Both tubings feature a 90 degree swivel to make installation a lot easier.

The copper base features a thin layer of thermal conductive material.

Antec bundles an air duct with the KUHLER H2O 650 but i just can't figure out the why (doesn't really matter if the air scatters once it gets passed the radiator fins) since you'd be better off adding a 2nd fan in push & pull instead.

The RGB LED looks a lot better than the one used with the KUHLER H2O 620/920 models.
