This is my first time building a PC, and I am considering an overclock later on. My CPU is an Intel i7-3770K with a base clock speed of 3.5GHz, and an ASRock Z77 Extreme4 Motherboard. I would like to do a pretty high overclock, as high as a noob like myself could get it. I was wondering what CPU cooler I should get if I do overclock. I would prefer water cooling because I like the way it looks better, but if high-end air cooling is better, i might get that too. I am not, however, going to make a custom water cooling loop because I don't want to spend that much money. also, My case has plenty of space for a large air cooler, it is an NZXT Phantom and I doubt I will put the 200mm-230mm fan on the door of the case.
