Interesting. I see those fans are only 3-wire so you are limited to voltage control so with the stock control only 64 discreet speeds (6-bit) and only on the System header (which is translated to the FAN-A I suspect).It's not a classic rack-mount chassis, it's more like a big cubic desktop case with all the system in a rack who takes half the space of the case (the other half is used to trap the noise while letting the air flows).
...
The air is taken on the top rear through an air filter, sucked by the fans on the top separation (not represented on the 3D view), blown at the front of the drives and above the MB, then it passes through the rack floor (by holes under the MB) and is exited at the bottom front.
Though the case is pressurized by the fans, exhausting the heat out the bottom appears to be counter-intuitive (heat rises).
