Pump

The pump included into the COOL kit is rather small, too. But you shouldn’t judge by the size alone – we’ve got a respectable device, Delphi pump from Laing.

The pump has a curious design. It is in fact a centrifugal pump with a rotor immersed in the liquid. Despite its small dimensions (only 6x6x4 centimeters), its characteristics are no worse than those of similar but larger devices.

Particularly, the performance of this pump is 350-400 liters per hour and it is capable of creating a water pressure of 1.5 atmospheres. This capacity should be enough to ensure proper circulation of the liquid not only through the CPU water-block and radiator, but also through a couple of additional water-blocks that can be mounted on the chipset’s North bridge and on the GPU.

An indisputable advantage of the pump employed in the COOL kit is that it requires a 12VDC power source. That is, it connects to a standard Molex connector of your power supply. It also means this pump must be situated somewhere within the system case. You can fasten it to the bottom of the case with a couple of screws or just glue it somewhere to minimize its noise. A sticky pad of porous rubber is included into the package exactly for that purpose – this material is an excellent vibrations dampener. Well, anyway, you’ll hardly have a cause to complain about the noise produced by the pump. It is no more than 24-26dB, according to the specification. According to my hearing, it is practically inaudible.

You shouldn’t worry about the extra load on your power supply. We measured the consumption of the pump and found it to be no more than 10 watts.

The reliability of this Delta pump is highest, too. Its mean time between failures is 50,000 hours which is equivalent to 5 years with something. Only high-quality components can boast such a long service time. By the way, if the pump fails, nothing too serious is going to happen to your computer because the pump is equipped with a monitoring tool. The speed of its rotor can be controlled in the same way as the system fans are controlled. To enable this, you must additionally connect the pump to a fan connector on the mainboard.
