I agree with this. Just annecdotally, I think your best bet in closed loop cooling is a Corsair H100. The best sustained overclocks I'm seeing with closed loop water seem to be using the H100. This is understandable, as it does have a monster radiator!
I'm thinking of getting one to replace my Antec Kuhler 620, but I'm going to just see how far I can get with the 620 first, just for fun. I'd try your H70 first, just to see how far you get. You may decide that the extra ~100-~200MHz aren't worth replacing your cooler over, but then again, if you're on this forum, you probably just won't be able to settle for less...
Just make sure your case can accomodate the H100 before you buy it, however. My Cooler Master Storm Trooper for example, can manage it, but many cases can't, or at least, can't without modification.Edited by anubis44 - 11/12/12 at 10:14am
