I just put together a gaming rig yesterday. I have the gigabyte ud5h z87 and Haswell 4670k. I am looking to overclock it to 4.4 ghz. What cooling system would you recommend I get to keep it cool enough to run at 4.4 without overheating? Also, How reliable is gigabyte easy tune? It automatically sets my 4670k at 4.0,4.2,or 4.4
