I thought just the one intake was strange, so you would recommend 2 intakes?
For any fish tank case, unless running one position at much higher rpm than the others, I always used side and bottom as intake and top and rear as exhaust. Bottom will feed cool air for the GPU, side will feed the top AIO. Back intake is possible too, but usually is the only spot without a filter.
I found similar results on the O11D Evo, O11D XL, NZXT H9, NV7. YES, was changing cases very often but now settled with the North XL.
Bottom fans, usually are louder than anywhere else in the case, specially something like the H9 that doesn’t have any bracket allowing some space between the bottom of the case and the back of the fan.
Just as an example, using T30s, I would have the bottom fans at 25-30% while side intake and top exhaust at 40%. Rear could be 30%.
The D30s, despite not being on par with the T30s for performance, are my favourite RGB fans.
Another tip, I used half the RGB fans connected to one channel of the included RGB controller of the NV7 and the other half to the other channel. As side and back have less fans than top and bottom, the included RGB around the motherboard was connected to the channel with less fans.
Regarding the video, I found that the NV7 didn’t benefit as much from vertical GPU mounting, maybe because is a larger case and the GPU won’t be too close to the side glass panel when horizontally mounted, who knows?
