should i add 2 more fans or 1 would be enough ? i was watching a vid on youtube and the guy in it was telling that if there are more exhaust fans it creates negative pressure leads to dust getting clogged up but if their are more intake fans it creates a postive pressure and the dust is reduced.but if the amount of fans is balanced what would that create ?
I've owned that case and ran one 120 front intake,120 rear,and of course the 140 top.
Worked fine like that(quiet too).
Currently run a 902 with rear 120mm,200mm top,2x120mm front intake.
CM 692 - 120mm rear,2x140mm top,140mm front intake.
Have added another 120mm intake to both on hdd cages.(300 doesn't have that option)
Tried the side intake thing and that fan and location in the pc was always dusty.
You're better off adding one or two front intakes imo.
Add an aftermarket hsf like a 212+/Evo if you want or need one.
Fits and cheap = really good performance.
