Ok here is the deal I currently have a ASUS P8P67 Pro and an i7-2600k @ 4.8Ghz and 1.44 Vcore. With my H70 with 2 Ultra Kaze fans cpu temps go to max 74C. Which is about my limit for my 24/7 folding. However I just got a Maximus 4 Extream and another i7-2600k and would like to reach about 5.2ghz. From my experience I do not think the H70 will be able to keep up. I am not ready to go to a full Water cooling setup. So I would like some real facts from users with experience on this. I know there are a lot of really good coolers out there DH-14, Silver Arrow, H70, Tuniq 120, hyper 212. But what will stand up to the super heat I will be producing. Thanks so much for the help!
