That actually isn't a watercooler. It is called a heatpipe cooler. It has these little air-tight tubes that are connected to the heatsink base. These tubes have a liquid in them. When the cpu gets hot, the liquid boils and rises to the top of the heat pipe where it condenses(you have to have a fan or two attached) to a liquid and returns back to the base of the heatsink. By doing this, it removes the heat from the cpu.
