Corsair H70 CPU Water Cooler Review

The Corsair H70

In Figure 3, we can see the CPU block. It is actually a device intended to transfer the heat from the CPU surface to the fluid circulating inside the hoses. In this model, the pump that makes the cooling fluid (usually water mixed with an anti-corrosion additive) to circulate in the hoses is integrated in the block. The cable you see in Figure 3 are to power this pump.

In Figure 4, you see the copper base of the block. The thermal compound comes preapplied, which is more common to see in cheap coolers. The surface covered by the thermal grease is bigger than most CPUs, so it may make some mess during its installation. It would be better if Corsair has included a tube of high-quality thermal compound instead of preappling it.

In Figure 5, you see the radiator. Like it happens on a car radiator (it also looks like one), its purpose is to transfer the heat from the liquid to the air that passes though it. This radiator has installation holes for two 120 mm fans.

The two 120 mm fans, shown in Figure 6, are simple, with no fancy colors, just plain black. They are not PWM-compatible and there isn’t any anti-vibration mechanism.
