Need to pick up some new intake and exhaust fans for my case(Mozart TX). Looking for good air flow but something quite at the same time. I picked up 2 Scythe fan a few years back and found it moved a ton of air but was extremely quiet. I could only hear it if I put my ear right next to it. It was a 21E and 21F. Sadly they dont make these models anymore so I figured I would see what brands/models you guys like for this situation?
