Water cooling can be a pain in the ass, but it's really worth it. You should buy Coolermaster HAF912. You should only really need Aftermarker CPU Cooler if you're going to overclock.
Nah i'm not going to overclock it (Indeed i should.. but..) it's more the sound when i'm doing stuff it does with ease, just the shite stock cooler can't keep up.
I will take at watercooling aswell i guess, but it's a lot more money though, right?
