Too much positive pressure vs smooth airflow?

[kd1011]

Would having 9X 120mm intakes (480 at the top, 360 at the bottom, and 240 in the front) and a single 140mm rear exhaust be too much positive pressure?

 

The rear of the case is basically mesh and all intakes are filtered. The case is a Phanteks Enthoo Primo, so it's quite tall inside, and I'm not sure if the opposing fans on the top and bottom would really be fighting each other.

 

From what I can tell it's a trade off between having cooler air on all the rads, vs the air cooling required for the motherboard and memory. 

 

The other alternative is to have the front 240 and bottom 360 as intake, and the top 480 and rear 140mm fan running as exhaust. Running the rear 140mm at low RPM should equal slightly positive pressure, and smooth airflow from the front/bottom to the top and rear.

yes

Positive airflow is good you cabt have enough of it so it doesnt matter if you have 100 intake 1 exhaust as long as it is positive it is good

There is no such thing as too much positive pressure unless your case is breaking from it.

For reference: this was what made me consider running the top as intake:

Also, the front and bottom intakes are somewhat restricted. All fans including the rear 140 are static pressure optimised, though.

There is NO such thing as too much positive air pressure, PC cases aren't air thigh anyway. You're completely right with running you rads as intakes and one rear exhaust fan will be enough.
