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.
