The Corsair H100
As with any sealed liquid cooling system, the block, radiator, hoses, and pump come preassembled, with the coolant liquid already inside. This means the system doesn’t need (or accept) any maintenance.
Figures 3 and 4 reveal the radiator, which is responsible for dissipating the heat from the liquid to the air passing through it. This 240 mm radiator supports two 120 mm fans and is intended to be installed at the top panel of the computer case. This means it will only fit cases with room for a 240 mm radiator on the top panel.
Figure 5 presents the 120 mm fans. They are simple and black, and they don’t support PWM control. Actually, the system is designed for you to connect the fans to the block, which has the circuitry to control them.
