I have a intel i5 2500k on a Intel® Desktop Board DZ77GA-70K inside the corsair carbide 400r. I wanted to overclock the intel i5 to at least 4.0 ghz hopefully 4.5 Currently I have the stock cooler I am looking to get a cpu cooler. I want one that will keep pretty cool, is easy to install and under 70$. I would like it to be somewhat queit but that's not to big of a deal. If it's on amazon that would be even better. Currently I am looking at the thermaltake frio advanced, thermaltake frio, and thermaltake frio and thermaltake frio ock. Out of those 3 which is the best in what I'm looking for. The other one I was considering is the hyper evo 212+ I think is what it's called. Is the hyper 212+ gonna be better even though its cheaper or no. These are the 4 I was mainly looking at but if you have other suggestions feel free to give some.
