Positive pressure vs. negative pressure

[ANNIHILATOR284]

Hi,

I have a corsair carbide 400r and I was thinking if positive or negative pressure is better when all the fan slots are populated and in what config

Can any one please help me in this?

Positive pressure helps to stop dust buildup in your system, have more intake than exhaust and you're good.

Negative pressure means better temps, positive pressure means more dust build up. Either way it's not that huge of a difference between the two in temps of dust or temps.

Having good airflow direction is pretty important too though. Intakes should be in through the front/bottom, exhausts should be rear/top. That way air passes over each component in a system instead of just going in any random direction

Positive pressure means less dust build up

I personally always try to achieve a positive pressure, because dust is a PITA, I loose a degree on temps maybe but IMO its worth it.

i think u have your facts wrong

^^^^^^^^ u got it right!

i have better temps with possitive pressure... odd

It really doesnt make a differance to temps tbh, unless you're insane and have something blocking all the fans

 

My bad, didn't even notice I said that

Matching air pressure is best if you believe Corsair

Positive is better if you believe Silverstone

All I know is a case with a lack of fans cause more dust to lay as there isn't enough circulation in the case. I've never seen any performance increase in positive or negative as my computer case temps usually sticks at 30°c
