The folks at CoolIT Systems seem to be onto something with their OMNI Advanced Liquid Cooler, a watercooling system similar to the Corsair H50.  It is a completely self contained waterblock, fan, radiator and pump which is billed to fit any single graphics card; the normal OMNI uses a 120mm fan and they will release one for dual card systems with a 240mm fan that might end up living outside of your case.  It is designed to be universal, so as you upgrade your graphics card you should be able to continue to use your OMNI ALC.  HEXUS tried it out on the hottest and loudest piece of graphics silicon currently on the market and were very pleased by what they saw. 

“What do you get when you mix the world’s first universal liquid cooling system with the world’s fastest GPU? We find out.”
