Hmm... Not sure but here is a hands on at computex.

"The H50 is Corsairs high performance CPU cooler. It is a maintenance free water cooling setup similar to the Cool IT Domino. The difference is that Corsair seems to have created a solution able to cool an overclocked Core i7 processor enough to top the TRUE 120 at the same settings. We were witness to two identical systems, save for the CPU coolers. System 1 used a TRUE 120, system 2 had Corsairs H50. The H50 was able to cool the i7 975 by 15C more than the TRUE 120 with Prime95 running 8 threads. That is really impressive for this type of water cooling setup and to make it even sweeter, the retail price is going to be around $79 in the US. Look for our review once samples are available."

Hopefully it is this good.

I see smaller heat-exchangers in the future going along with smaller NM,s .
