I'm going to overclock an i7 3770k. The refurbished one is $30 cheaper and since im still a teen, I don't have that much more money. The MAX that I can spend is $100 no more.
Have you already bought the i7? I know how hard money is when you're young, and I figured I'd let you know that when you're gaming, there's no difference between the i7 and an i5 for $100 less. (Games can't / don't use hyperthreading, which is the only difference between the two chips.)
That being said, what sort of overclocking are you looking to do? There's virtually no scenario where I'd recommend a closed loop water cooler except in something as extreme as a Falcon Tiki.
Buy yourself a Hyper 212+ and an aftermarket fan - I like Corsair's. You'll be able to hit a 4.4-4.6 GHz overclock easily, depending on the roll of the chip you got.
