Okay forgive me the phat marketing lingo, this is a copy paste from the press release:

The Thermaltake PW880i is a powerful liquid cooling solution for the core of your PC- the CPU. With a 24cm radiator equipped with two 14cm fans, Thermaltake PW880i is the ideal device for efficient heat dissipation. The solid CPU water block is made of pure copper with delicate brazing technology. Supporting most mainstream CPU sockets such as Intel LGA1366 and AMD AM3, the PW880i sports excellent cooling performance for demanding users and overclockers alike. As the tank and pump can be placed outside the chassis it offers two practical advantages: you gain more space within the case itself and maintenance is made easier and more convenient.
