Asetek WaterChill KT12A-12VX
 

Asetek is a leader in high-end cooling with a reputation of
outstanding performance from their products and kits. The WaterChill
KT12A-12VX certainly didn't disappoint with performance that kept one of
the hottest processors I have worked with around the 40C mark. The
ability to cool the chipset and video card were impressive to say the
least again lowering the operating temperature of my X800GTO to
temperatures I thought impossible.
