I am getting either i5 6600k or the 7600k and plan to oc on my z170 board. I don't know what aftermarket cooler I should get though. I want to try to stay in the 20-30 dollar range so I was mainly looking at the Cooler Master Hyper 212 EVO (I'm sure you've never heard of that B4 xD), the CRYORIG H7, or the CRYORIG C7. Please leave any comments of other ones that you think may be better.
