Dude, unless you have the money and you want to go through the dangerous process of water cooling your cpu (if you're a noob, I do not recommend it)? Zalman fans are very nice... but, yes, I have to admit, water cooling is amazing. Phase change is better but $$$$$. One water block is like around $1000. Anyways, unless you overclock, and I see that you do, I would recommend the air cooling. But, since you do oc, water cooling is the only way to cool, stable, and fast components. The kit is very nice, although I suggest you go through ww.frozencpu.com and check out all their stuff. They have some nice stuff there. There are some cases that actually have a water cooling spot built in, like the ones in frozencpu.... yeah....
