It's quite amazing how it cools better than some of the more expensive water cooling systems. A friend of mine is using the H70 in his build and we got pretty much the same temperatures even though the V6 was like $30 cheaper at the time. I'm pretty satisfied with it and I'll probably go with heatsinks over waterloops in my next build. I'd just want to try a different thermal paste, I wanted to get the IC7 but I heard that it might get me into trouble if I ship it through aramex so I stuck with the original CM compound.. it does an impressive job for a 'stock' paste regardless!
