Positive Pressure in Haf X

post #1 of 2
Thread Starter 
Hi all!

I've been doing some reading on cooling and airflow and the benefits of positive pressure. The problem is I don't know how to determine whether I currently have a negative pressure or positive pressure in my case.

My case is a Haf X Blue edition. There is a 240mm front fan for intake and a side 200mm fan for intake. For exhaust there is a 140mm rear fan and two 200mm top fans. Also since I'm using an H100 for a push/pull setup, I have four 120mm also exhausting out of the top.

Based on this, I'm assuming I have negative pressure in my case. How would I re-arrange things to have a positive pressure. Also, is there a definite test for this or is it pretty much a guesstimate?

This may sound obvious, but turn the two top exhaust fans around so they are intake as well. Then you have TONS of air coming in, and only so much being forced out, all through the rad if you want.
