Processor Water Block

The Processor Water Block is the cooler that mounts to the processor which passes the coolant over the processor (CPU) in order to take the heat away. Traditionally a processor cooler uses a large metal heatsink to draw the heat off the CPU and then a fan to disperse the heat from the heatsink to inside the case which eventually is exhausted out of the case via further fans - A Waterblock like this transfers heat from the CPU to the coolant which then travels the loop and ends up being cooled by the radiator.
