You people that think we can flow as 4, 5 or 6 vents worth of air into a case without have similar vent area for air to flow out.
As I have said before, airflow is is just like water flow. Granted, air compresses and water doesn't, but the same principles apply.
We can't have airflow into a case without the same amount of airflow going out of it.
The amount of air that will flow into a case and compress before fans reach their static pressure rating point is very very little .. a fraction of the pressure change it takes for us to feel a difference in pressure in our ears. You know, like when we roll up the car windows while driving 50mph, drive up into the mountains or fly in a plane.
Once the fans reache reach their static pressure level there is no longer any airflow, only the pressure. "Static Pressure" rating is the maximum pressure fan is pushing when airflow stops. Stop and static mean there is no movement
How can you people not understand that if we have 4, 5 or 6 fans on intake vents we need simliar exhaust area, and that 1 or 2 exhaust vents plus the small amount of area from screw holes and cracks around panels is not going to be a similar amount of area to exhaust that air .. and that this much smaller airflow area severely limits the amount of air the intakes can flow into the case?
Surely you guys understand that more air can flow thru a 120mm or 140mm grilled vent than thru all the cracks around side panels, screw holes, and other small air leaks in the case.
