Recently I decided to upgrade my computer after a long period and while I was at it, I thought I would revisit my cooling setup. I have always been a little concerned that my case might have negative air pressure, and with some of the newer graphics cards it appears that they exhaust outside of the case, so that only makes things worse.
I would definitely prefer a case with positive pressure and this is initially how I set-up my computer. My concern is my intake fans all have filters which cutdown on airflow. So, even if the rated air intake is higher the actual air intake may be a lower rate, thus negative air pressure.
Does anyone have any idea how much the average wire mesh filter cuts down on air flow? I would guess it must be a significant amount, so I would appreciate any rules of thumb or links to guides on this topic.
