I've done some moderate overclocking but I am thinking of taking my e6550 to around 3ghz. I have a midATX tower. What would be some good choices for air cooling? Thanks.
It depends if you plan to go farther then 3ghz. Overclocking can be really addicting and you dont want to find yourself with a $20-$30 dollar cpu cooler trying to overclock past 3ghz. However if you dont plan on high overclocks, then the Arctic Freezer 7 Pro is a great and cheap cpu cooler. If you want to try higher overclocks then something like the Tuniq Tower or the Thermalright Ultra 120 Extreme.
