Instructions: Do-it-yourself water cooling

The pump

The pump or the company that makes it should be familiar to every pond and aquarium fan. If the company 'Eheim' has a good reputation in this segment, the choice in hardware circles is increasingly falling on a product from this company. For use as a water pump in a water cooling system, the amount of water pumped, the reliability and, especially important for us in this case, the low operating noise. The copy at hand was the relatively strong version 1048 with a flow rate of 600 liters/h. The device is connected via the 220V house line, the consumption of 10 watts is well above that of a normal CPU fan, but it still seems reasonable '/images/280f67342e49fa3d7eebc47509af00b5.png'>

Hoses and Co.

In addition to the individually listed main components, we elicited a number of other important components from the package Utils. Because what wouldwater cooling without the hoses and adapters required for connection? The 'Water-Cooling Kit' contains two plastic hoses with an inner diameter of 6mm. The length of the individual sections must be selected during installation in relation to the required dimensions. The high rigidity of the PE hose could turn out to be negative here. For the connector system used, however, a rigid material is the number one requirement. True to the motto 'Plug & Play', it is sufficient to first push the hose gently into the socket until there is first resistance and then press with a little force over the clearly audible 'sticking point'. The connection established in this way is watertight and can only be released from the anchoring again with a 'trick'. A practical alternative.

Two adapters are included in the set so that the incompatible pump can also be connected to the circuit. Incidentally, the package has a surprise in store for filling the circuit. Without the otherwise common overflow container, the circuit can be completely closed by a valve system after the filling process. We will go into this 'Fill and Bleed Valve Assembly Kit', consisting of two valves and two T-pieces, in more detail later. The scope of delivery is rounded off by a bag of thermal paste, four fabric stabilizers for Intel CPUs and a small number of screws.

Installation

The documentation contained in the package is limited in English to the installation of the cooler and the filling using the 'Fill and Bleed Valve Assembly Kit' . With a bit of luck, however, we came across more than informative instructions online, which deal with the entire installation including the pump relay (not included in our set). Prior knowledge should nonetheless be present.
