Since the case only came with one front case fan, and I have loads of drives I need to add a second, I obviously want them to match so I ordered a couple of these..

Noctua NF-S12B REDUX PWM 1200RPM 120mm Quiet Case Fan

Depending on what they are like, I may have to put some in my main PC (in sig), and some of the Industrial ones on my Corsair H100i
At 18db the REDUX ones shift nearly 60CFM, so that should be plenty.
