I'm using multiple GentleTyphoon AP-15, which was the king of 120mm fans at least back when I researched it in 2014. I'm updating my case and I'm debating between Corsair 750D and Corsair 900D. Unlike the 750D, the 900D can have drives placed in the bottom compartment away from the intake flow.
I have five 3.5" drives, and probably more in the future. If my AP-15 fans can handle that kind of obstruction, I might opt for the more manageable 750D. Kinda hard to test before buying the case
