Hello, I almost finished my new rig and want to have really smart advice for long time period which cooler to buy. I have very delicate taste and want to see offers. Budget is quiet not impressive, but considering that all rig was made from good parts, I don't want poor quality products. I have 4690k on Asus Z97-K powered by 750W modular CS750M PSU. I was considering to buy H60 and would like to know what I can get from it and how much I can overclock my cpu?
