I have a Corsair 230T case and I want to liquid cool my i7-4770K. I am currently running 77 C at 4.0 GHz. In order to achieve this speed, I have to over volt to 1.215V. I am using the Cooler Master Hyper 212 EVO and the temps I am getting aren't where I'd like them to be... what should I do to increase my cooling performance? I've looked into the Corsair H100i and the Cooler Master Seidon 240M. Any suggestions?
