I am looking to set up a negative pressure flow in my future build and am trying to calculate my CFM's. The plan as it stands is to have a push-pull exhaust blow hole with a corsair H55 and then one front intake using Enermax TB Silence 120mm fans. I am just unsure if the CFMs will actually be greater out than in with this arrangement.

The system is my current rig, but I am going to house it in a modded steel locked box for fun. The reason for my purchasing the H55 isn't really to get cooler temperatures on the APU, but to try to push some hot air out to reduce ambient temperatures because I am planning on placing a portable projector inside the case as well, so it could get a little hot. Thanks!
