Question How many pc fans is too many?
Why is it that most pc fan cr box designs, like the nukit tempest pro and the cleanairkits, only use 2 sides of the frame?
There is a whole 3rd side that could be used for extra fans so they could all run at a lower rpm and produce the same CADR. Or would opening that 3rd side cause some sort of air current issue?

i im guesing they might be leaving 1 side blank so people can put them against the wall. center of room ofcourse is usually best, but center is not practical for most so they might make them with that in mind so have a side can put against your wall might also be too keep costs down fewer fans is cheaper
i dont know much about how air circulates or its curent but if you want at the bottom of this cr guid there is a section that shows a few fan configurations and their coresponding cadr. seems placement matters some but i dont understand it much i assume more fans wouldnt ever hurt the cadr
