Couple questions here. First of all, I have a i7-3770k processor (don't worry, I do plan on overclocking). I know I should get a better fan (I'm using the stock one right now) but what should I get? Don't worry about price, just give me good brands and models. (Oh yeah, I have a Corsair Obsidian 650D) Second, how do I take off the CPU fan I have right now? I've seen numerous ways but I want to know what you guys think is the most reliable.
