Optimal fan placement size for phanteks p300 (comes with one 120) so do I add 3x 120 for 2 in 2out or do I add 3x140 because top and front support 140s but not the rear so I would have 2x140 in top exhaust 140 and rear exhaust 120 (again can’t put 140 on rear)?
 
Solution
Since hot air rises, case's airflow rule of thumb is: front & bottom - intake; top & rear - exhaust.

Here's how i'd set up fans inside Phanteks P300:
front - 2x 140mm intake
top - 1x 140mm exhaust
rear - 1x 120mm exhaust
