That is a good build make sure you get a decent cooler though I used to have this cpu and it got up to 80 degrees with stock cooler on bf4.
The Hyper 212 is for the CPU. The case itself is already good enough to not require an extra fan, or at least from what I've read that seems to be it since it's very well ventilated and already has fans integrated. Maybe if I find it has a problem with overheating then I'll buy a new one. For now I think it's fine.
