Case Airflow: Positive or Negative Pressure?. Based on comments in , I now have a question about the ideal way to set up airflow through a case. It seems that there are two camps in this debate -- those that think the air pressure in the case should be positive,...

that this can effect the cpu fan's preformance. What do you guys think? If you must have one, is it better to have a positive or negative pressure in your case? Which brings me to my next question... what about having no fans at all for intake? Just a bunch...

of sucking infiltered air into the case. These cracks are primarily holes in the case itself, but are also the CD-ROM drive and the floppy drive. Have a negative pressure in the case will cause a tiny bit of air to be sucked in through the CD-ROM, pulling airborne...

that the HAF 932 and the Antec 900 may be prone to acquire dust more frequently than the other cases. The HAF 932 has no dust filters. I am guessing that it is better to have all the side panels on the case (right?)? Is it better to have it cramped...

negative airflow. Just as a note, negative airflow reduces temperatures by eliminating hot air from being recyclied inside the case. If your case has little vents in various areas, negative pressure could simultaneously pull in cool air from those vents...

in as if it was blowing out it would suck cold air out (that is if it a low side fan) I always set systems up with a little more coming in than going out. The reason for this is tha if you have negative pressure in the case .DUST will be sucked in through the...

1 or better 2 fans at the back/top plus PSU fan blowing out. You will need to have negative pressure in the case if You do not count side fan. If You will have positive preesure already before side fan, it will do nothing running @400 rpm as it cannot produce...

front at lower speeds to see if that helps. Right now you have 2 fans in and one out which means you are pressurizing the case if the graphics card and PSU are not blowing enough air out. Normally you want negative pressure so cool air seeps in all the vents....

molex everywhere. I am trying to get the negative pressure going for the case. From researching I thought of doing... 1 top exhaust fan = 1 x 200mm Antec Fan(comes with the case) 137CFM 2 back exhaust fans = 2 x scythe 120mm slipstream 68.54CFM Total...
