Good cooler to keep i5-6600k cool

Solution
Totally. They are all relatively similar. Just with the H7 you get a lot of mass which is important, a quite nice fan, nickle plating, quality pipes, good solder, and even a decorative tower top. You'd have to spend a lot more to get all those comforts from a different brand, which is why I like Cryorig coolers so much - a quality cooler at a fair price.
Idle is under 30C, usually around 28.
Under load not 100% sure, i've never seen my 6700k hit 80c. Gaming it is usually around 70-72C That is with an H5 with the fan swapped for a 120mm due to space restrictions in my low airflow ITX build.

I have an H7 on a BCLK OCd 6400, OCd to around 4Ghz. Not sure on the temps there - it is my wifes rig and doesn't get monitored much after i got it stable.
 


So you think that H7 will do great for my ATX build?

Case is Fractal Design R5 with 3 top and 1 rear exhaust fans and 2 intake fans in front?
