[SOLVED] Fan blowing in or out

[Shaftyz]

Since i ordered a splitter but it hasnt arrived yet, I currently have 1 fan in the back, should it be blowing air in or out? Slot where i put psu has holes in the bottom so psu air is going out. (Case has 120mm windblade fan)

It also has slot for 2 fans in the front, 1 on top and 1 back

Usual setup is with front/bottom inlet and back/top out. If possible, a little more air in than out but equal flow is fine. Can't look only at fan size and RPM but also their maximum flow rate.

Ok but for example, currently i have 1 fan in the back since the splitter hasnt arrived yet. Should it blow in or out

Out, it's important to get as much of hot air out as possible, air will find it's way in from no working fans or holes for them.
