Static pressure or AF case fans?

[ConorG]

I'll be getting an aftermarket cpu cooler (cryorig h7) so there will be somewhat of an obstruction in my Define R4. I'll be replacing the stock fans and was wondering if my rear outtake should be static pressure?

Rear outtake should be an AF , SP's are for Rads and Heatsinks.
