Hi all,
I'm working on the fan layout for my 740 Air Case and wanted to share this design idea—sorry about the drawing quality!
The layout I have in mind includes:
1. Two 140mm Noctua units on the radiator at the top
2. One 140mm Noctua exhaust on the back
3. One 140mm Noctua unit at the bottom to draw air in (does this help with GPU cooling?)
4. Three 120mm Noctua units on the front to draw air in
I'm curious if this will provide good pressure inside the case and would appreciate any suggestions or adjustments.
Thanks!

Airflow direction is satisfactory except when moving the bottom fan, as it blocks your PSU. I prefer the Noctua Fractal Design Venturi HF Series Black Fluid Dynamic Bearing High Airflow 140mm Case Fan and the Fractal Design Venturi HP Series Black Fluid Dynamic Bearing High Pressure PWM 140mm Radiator/Heatsink Optimized Fan, which perform well for me.

Eno, let me clarify: the bottom fan doesn't obstruct the PSU because it's on the opposite side of the case. The 2-compartment design keeps the PSU on the other side, and you can see the SSD enclosures in that compartment through the motherboard opening.

I didn't realize that was a sweet case, huh?
