In my opinion, i'd prefer to get as many case fans as the case supports!
So you like the sound of turbines spinning up near your gaming area? XD
I would recommend using as few fans as you can to achieve the thermal levels you want. Or, using many fans at low RPMs fan curve to mitigate noise. But, this should be done with more air flowing in than out so a positive pressure is created in the case.
LOL of course not! but my room gets very hot very easily because I live in south Florida, and I need all the fans I can get! I’d just get those Corsair quiet edition fans and everything would be good and dandy. Also the case I wanna get (NZXT S340 Elite) only has four fan mounts so either way it wouldn’t be TOO noisy in my case. (pun intended :P)
Ayyy, that was pretty punny. ;)
