AIO liquid coolers consist of a motorized pump, a liquid-filled loop, a radiator, and fans, all in one package. This cooling solution has a few benefits over heatsinks, namely that they provide consistent cooling for your CPU with less noise. While heatsinks are great at heat spikes (sudden increases in heat on your CPU), liquid coolers are better at removing a lot of heat at a consistent pace. This is preferred for gamers or editors who will be using their machines for extended periods of time.
Liquid coolers typically come with 120mm, 240mm, and 360mm radiators. Please check your case's specs to see which radiator size it supports! We can also offer different sizes, like 140mm, 280mm, and 420mm, but please contact us for a custom option for those sizes. If you see an AIO liquid cooler that you want on another website but not here, let us know and we'll add it!
