Apologies, I know this has almost certainly been asked before, but what is the consensus on setting up case fans? More air in or out?

Thanks.
 
More air in with decent filters in place will hugely reduce dust problems inside the case.

Negative pressure can have some cooling advantages but most PC cases aren't ideally setup for that especially in respect to dust.

Thanks. But what about cooling and ensuring hot air is exhausted?
 
Looks like I'll end up with neither and go balanced given the configuration of the case I'll likely get will only support negative or balanced and turning the rear or top fans around will completely screw the airflow.

this is a massive debated and you will not get the same answer.
my O11 mini ran negative and was silly cool... but and O11 mini and 9 fan points


what case do you have.. what fans do you have and what handwear do you have
 
No case yet as there was a problem with my order.

4x 140mm Be Quiet fans. 7800X3D. Not sure of card yet but could be anything so any level of power.
 
I think mine is positive pressure, an 011 Air Mini with stock fans and running the Noctua NH P1. So 2 x 140mm at the front sucking in and 1 x 120 above the heatsink blowing out. Seems OK although will fit filters to the front fans soon.
