As an experiment we tried this water-block in non-standard configurations: 1) without the central tube and 2) with the water coming in from the sides and going out through the center (the imitation of an incorrect connection).
You see the results degenerate considerably (this test was performed under different conditions than the test of the assembled system below, so you shouldn’t compare the two diagrams directly).
The GPU water-block boasts an acryl cap of an impressive thickness of 2 centimeters. The fastening suits almost all graphics cards, save for GeForce 6800 GT and Ultra.
This water-block can’t match powerful blocks for the central processor, but can easily handle graphics processors of current (and upcoming, too) graphics cards as it could take off as much as 300 watts of heat in our tests.
The manual on the chipset water-block (its design copies the GPU block, but with vertically positioned fittings) describes an ingenious way of mounting it on mainboards that have their default heatsink fastened with the help of wire loops – that’s a big problem with some other cooling systems.
