I am looking at getting a water cooling kit for a new comp that i will be building. I understand how water cooling works and was wondering if you guys could suggest any good kits that work the best for overclocking. I was looking at the koolance exos thing and that looked pretty good. is there a big difference in how well it kools between all the different kits? is it mostly u get what you pay for? i dont necesarily have a price range, mostly lookin to get the most bang for the buck.
