Does this fan setup sound ok?

I'm planning a build in a Lian Li O11 Vision Compact case in 'display' mode...glass panel on top rather than mesh and radiator. I was thinking of putting the rad at the side with 3x120 fans exhausting through it, three more 120 intakes at the bottom under the vid, and two more intakes at the back (instead of the usual thing of having them as exhausts). The other option I considered was swapping the radiator fans for reverse ones to suck air in, with the two back fans as exhausts, but I don't like the limited options for good non-rgb reverse fans. I hate rgb!
Any views?
Any recommendations for non-rgb reverse fans that are deathly quiet, massively effective and cheap as chips?

(Edit: Just looking at Arctic P12 Reverse flow 3-packs...they look quite good and I can turn the rgb off of course.)

Either option sounds OK
Both should give plenty airflow
The radiator as intake usually gives lower
Cpu temperature
But if your cpu is at an acceptable temperature
The difference may not be enough to
Worry about anyway

Yes artic p12
Or thermalright fans
But theres so many thermalright models
It gives you a headache comparing them all
 
IIRC the side (where you want to mount the rad) has a mesh on it, whereas the rear mounting spots have larger holes. My concern would be dust/pet hair/etc filtration. The mesh isn't exactly a filter but does help quite a bit.
Aside from that minor concern I don't see any issue with the "reverse" solution. Your CPU might be a touch cooler ruinning it the other way around but I don't think it'll be a noticeable difference.
 
The back of the case as exhaust and intake fans with the radiator on the side would make more sense.

That way cool air used with raidiator, intake fans from the bottom would supply cool air to the GPU, and any hot air rising from CPU exhausted out the back.

Slight negative pressure works better as well imo - i.e. more exhaust than intake.

Yes, that was my alternative option and pretty much what I'm going for:
Buy 2 sets of 3 Arctic P12 Pro Reverse fans. Use one set as bottom intakes. Swap the other 3 with the radiator fans and have as intakes on the side. Then use two of the radiator fans (from the Arctic LF III Pro) as exhausts at the back. This is the lowest cost to performance solution and I'll just have to turn the RGB off. All Arctic fans + positive pressure = stealthy black, rgb-free, and dust-free interior! :)
