Intel has created a self-contained watercooling unit that will enable the latest Pentium Extreme Edition chips to hit 5GHz with ease. It's still a prototype, but who knows? The cooler is based on solid copper water block, a DC brushless motor centrifugal pump and radiator, cooled by a 120mm fan. The main body of the unit is made of injection-moulded plastic and can be mounted on ATX and BTX boards. The prototype is extremely well designed and manages to run a 3.8GHz Extreme Edition chip overclocked to 5.01GHz at 62'C. Intel is currently looking to work with a technology partner to developer commercial coolers around this design. Because Intel designed it to be assembled from commonly made parts, final retail coolers are expected to cost less than $50!
