Water cooling reservoirs
In a water cooling system, expansion tanks are used to accommodate the fluid of the entire system or to take into account the expansion of the coolant. They can also be used to top up the water cooling system or to vent it. Mostly the expansion tanks are made of plexiglass or aluminium, but there are also more exclusive versions that enhance the interior of your PC even more. The separately available pumps are partly already installed directly in the expansion tank.
At digitec you will find expansion tanks of the following brands: Alphacool, Aqua Computer, Bitspower, EKWB, Koolance, Monsoon, Raijintek and XSPC.
