The casing for the water pump also serves as the water tank. With 900 rpm, the pump's performance reaches 70 liters per hour. In the tank itself, there is a blue LED lamp as well as one of the three temperature sensors. The tank is filled with distilled water through an opening, unfortunately a rather small one, on the top of the tank.

The water tank with integrated pump.The tank is filled through the small opening on the top side (see the screw).

Filling the water tank is a bit difficult because the tank lacks a mechanism for balancing out the air pressure, so it's constantly on the verge of overflowing. The easiest method of filling the tank is still to use a syringe. Also, a large part of the water supply is already in the tubing system itself. Thus, the pump should be operational upon being filled. The power is supplied by the PC in the form of a 5.25" connection.

At this point, because the graphics card is not being cooled, and because it takes some time to fill the tank, the card should not be installed yet.

Once you've gotten over this hurdle, there's nothing more to stand in your way. The water circuit is perfectly sealed and the pump generates a very low noise level.
