Case fan questions.


Recommended Posts

Hi everyone. So I recently built a new computer system. My case is the Fractal Design R5. It comes with 2x140mm fans. One in the front for intake and one in the back from outtake. I need to know the ratio of intake to outtake to maintain negative pressure. I can add one more 140mm in the front and one more 140mm on the side(it won't be filtered though). I also have Moduvent on the top which allows 3x140mm on the top. For negative pressure I want 1 intake for every 2 exhaust?

technically, negative pressure in any given room can be generated and maintained by having the air inside pulled out with an exhaust ventilation system, no forced air intake.

i preferred a balanced intake and exhaust ventilation system though, it's just me.

nice! just have a good airflow inside that case and it should be alright. your ambient temp may vary though. but i'm absolutely sure you have a lot better ambient that mine, we're hitting the 40's here now :whoa:

how i hate our summer.
