All-in-one liquid cooling without the custom-loop hassle
An AIO liquid cooler comes as a sealed, pre-filled unit, so you get the benefits of water cooling without planning tubing runs, filling a reservoir or bleeding air out of a loop. Heat moves from the processor through the coolant to the radiator, where it is released away from the CPU socket. For many builders this is the simplest way to step up from a standard air cooler while keeping maintenance to a minimum.
