Fan configuration

[Wjohansson29]

I have recently bought new fans for my Phanteks P400A. I went from one 140mm and one 120mm front intake fan, one 140mm top exhaust fan and one 120mm rear exhaust fan to three 120mm front intakes, two 140 top exhaust fans and one 120mm rear exhaust fan.

This means i am probably getting negative air pressure in my system.

Would you guys configure the fans differently?

 

BTW all fans except the rear exhaust fan are corsair LL120 and LL140 fans.

Personally, I have seen many people support positive airflow because its easier to manage dust, so if you're in a dusty environment I would advise switching to a positive airflow

 

I have seen people claim both have their benefits, but closer to neutral is always better

I would say you should be fine unless you live in a dusty environment, but if you do I would go for a more positive air pressure system.

 

IDK too much about that case so I'm not sure whether you could do this, but maybe switch 2 of the 120 intakes for the 140 exhausts? This would give you a positive air pressure. But I wouldn't bother unless you actually have a dust problem

Are you worried more about dust or temps? Temps-wise doesn't matter. Dust wise intakes should have filters and you should keep the room clean of dust. The pressure thing is very greatly over-appreciated. Even the LTT one year test showed that most dust was in places where the intake fans were. Not much difference otherwise.
