fan setup

[MorganO]

i want to create positive pressure in my case 

my case fans are as follows PH-F140SP ALL AT 1225rpm(or there abouts) 100% they arent loud with 2 as intake and 1 as exhuast

my radiator fans are as follows Dynamic GP-12 (attached to an fractal S36)from fractal run at 500-600rpm, i seem to be getting quite a bit of dust inside my case(brand new) so am i creating positive or negative or neutral pressure?

many thanks

Idk if this is in the right place :/, if anyone could help me, speedfan doesnt seem to work, and all i can use is AI suite 2.0 (asus x79 pro board)

So you have total 5 fans, 2 intakes and 3 exhausts? That would be negative pressure. Simple way to determinate positive/neutral/negative pressure is amount of fans intaking and exhausting. Though anything obstructing airs path will have effect as well as fans speed and amount of air it moves. But in general:

• 2 intakes and 3 exhaust is negative. Removing 1 exhaust would make it neutral.
• 2 intakes moving faster/more air than 3 exhaust would be neutral or close to it. Removing 1 exhaust might tint it towards positive.
• Adding 3rd intake and removing 1 exhaust would definitely make it positive.

6 fans 2 in 4 out  3 of them are attached to a radiator should i flip the fans to intake and pull air through the radiator ?

No, if you don't have dust filter for them. You can add more fans to side and bottom mounts. But start by removing or moving rear exhaust to somewhere as intake. Next would be tweaking intakes to move more air than rad fans.

i have the evolve atx tg, which can only fit 2x140 intake, or 3x120 in, and the and the 140 in the rear, the case fans(phantek the 3 case fans are already running at max) the radiator fans are running at the lowest speed

Oh, ok. Mind updating your profile with that case? I was looking at Aerocool one which is listed there. Anyway, remove rear exhaust. Phanteks cases aren't among the best when it comes to fan mounts and general airflow.

ill update it shortly, so if i remove the rear one will the negativity drop?

Yes. It will still be negative or close to neutral, but there isn't more you really can do.

ok, ill try that im just surprised at the ammount of dust already  had the case like 3 days now
