I'm looking g at a few coolers for the 8600k, and would be looking to do a small OC of about 4.8Ghz The main coolers I'm looking at are the Corsair h80i v2, or the CM Seidon 240V. The other options are some low profile, top facing coolers. I've seen the Cryorig C1 or the Big Shuriken 2 Rev.B. But I don't know if there will allow for any OC. Tower style cooling is not an option for me unfortunately. Any advice would be appreciated.
