My build is an ASUS ROG Maximus VIII Hero.  I tried the Noctua cooler but its big and my CPU temps idled around 40C.  I replaced the Noctua with a Deepcool Captain 120EX liquid cooler and the temps dropped to around 31/32C and it was as quiet as the Noctua.  I'm using a "BeQuiet" case that has room for two CD/DVD drives and it too is quiet. 

The Noctura is HUGE.  We did not use the second fan.  It was hovering in at <40C when I left it.  Sufficient, but definitely not as good as water cooled.  My old water cooler (Corsair) was actually louder than the Noctura fan!
 
Not familiar with BeQuiet Cases, I have been using Antec Sonatas.  Very well built, but today I like trhe Fractal Design better because of the cable routing.
