Frostytech have done an exclusive review of a totaly brand new heatsink called the Xigmatek AIO-S80DP. The AIO-S80DP is a self contained watercooling heatsink; pump, fluid, heat exhangers, fan and all!
"What makes the Xigmatek AIO-S80DP heatsink unique is that it is an all-in-one watercooling based thermal solution. Coolant runs through the metal veins of this heat exchanger, and it is only this liquid which works to transfer the heat absorbed from the processor into the surrounding environment. The heatsink is set up with two 80mm sized radiators, positioned with direct connections to the reservoir below, and a fan set dead between them. Moving the coolant around the inside of the AIO-S80DP is a small 12V pump, set into the body just below the 80mm fan. The pump utilizes a ceramic shaft that rotates at 3100RPM, and moves about 72 L/hr of liquid at a head pressure of up to 1.2M. "
