Praetorian fan question.

[AuroraProject]

The Praetorian has two intake and two exhaust fans, once you have a PSU installed you would have 3 exhaust fans. If you have more exhaust than intake do you get problems? Should I turn the blowhole fan over so it's an intake?

 

[fuzzy34]

no, the case will be fine with 2 intake and 3 exhaust

you need the blow hole to exhaust just for the fact that its on top

If you turned the 80mm blowhole into an intake then it would just blow hot air down to the components because hot air rises.

There's nothing wrong with more exhaust. It's just that there will be negative air pressure in your case and it will suck dust from everywhere. See here for case air-flow guide

 

[Elledan]

Normal case fans are not nearly powerful enough to create a significant airpressure difference between the in- and outside of the case.

What happens when you've got more exhaust capacity than intake is that air will be pulled into the case through the many openings of the case in addition to the intake fans. If you were to seal all of those openings, the exhaust fans would simply slow down, and the intake fans speed up until they reached an equilibrium.
