PC Water Cooling Reservoirs
Your pc water cooling reservoir capacity is an important variable in your liquid cooling system. The computer water cooling reservoir size determines the overall cooling capacity of your water cooled system. Increasing the reservoir size increases the amount of water in the system which allows for greater heat dissipation.

FrozenCPU carries the latest computer water cooling reservoirs from external reservoirs, passive reservoirs, internal reservoirs, bay reservoirs and reservoir accessories. We stocks the latest Bitspower reservoirs, Danger Den reservoirs, EK reservoirs, Innovatek reservoirs, Koolance reservoirs, Primochill reservoirs, Swiftech reservoirs, Tecnofront reservoirs, ThermalTake reservoir and XSPC reservoirs.
