that was the initial plan yes, but i never got a definitive answer as to whether or not that would be capable of giving me positive pressure. is it better to have 2 as intake, 3 as exhaust, and have to mess with fan curves to get +pressure, or to have 4 intakes and a single exhaust?

That makes sense, but do you think a single exhaust fan in the back will be capable of moving enough air to maintain reasonable temps? I would have 4 140mm intakes, 2 pulling air through a rad, and 2 pulling cold air in the front. What you say about having intakes running at higher speed makes sense, that will maintain much higher positive pressure and push air out back gratings as well.

I am reluctant to put a dust filter on the back intake and use that fan as an intake, because the gratings around the fan, which will be unfiltered, will also pull air in, thanks to fluid dynamics. I really want positive pressure, because i dont want to have to deal with excessive dust buildup. If I were to use the 4 fans in the top and front as intake, with the front fans set to very low rpm, and the back fan at high rpm, would this give me enough airflow to maintain good internal temperatures?

Hi everyone, New user here, and first time building a PC as well. I've been delaying my build because I am unable to decide on optimal fan setup, and was hoping to get some input. Relevant hardware: -Phanteks Enthoo Pro M TG -i7-7700k -NZXT Kraken X62 -ASUS STRIX 1080ti -ASUS ROG maximus code IX My question is, how should i set up my fans? As it stands I have room for 5 140mm fans, 2 in the front, 2 in the top, and one in the back. I was planning on putting my 280 rad on top as exhaust, with two unimpeded 140mm fans in front as intake, but i am afraid this will give me negative pressure with the back fan also being used as exhaust. I could put 3 120mm fans in front if i remove the ODD enclosure, but i need a blu ray drive. I have 3 Corsair HD 140s (600-1350rpm, 74 CFM) and the 2 stock NZXT fans (500-1800rpm, ??? CFM) that came with the x62. I was thinking that the radiator fans wont move as much air as the front intakes (obviously they wont, but i dont have any numbers on this), so maybe i could still get positive pressure with this setup, but i would like to have some input from experienced builders before i begin. Any suggestions would be wonderful.
