Hyper 212 evo or mugen 4

Cooling a fx 8320 which one is better?

can get either for the same price and quite prefer the mugen for its lower height.

also i've seen on silentpc that it out preforms a lot of good collers

your impressions?

I have the Hyper 212 Evo. It's a pretty good heatsink for the price, and it keeps the CPU very cool (Which is also an FX-8320). It fits fine in my Corsair Carbide 200R, which is a midtower. 

From what I've looked up, the Mugen 4 is quieter and probably better at cooling your rig. It's more expensive, so that's for you to determine if the price is worth it.
