Default Re: Do I want pos / neg case pressure?

I have two side fans. The one on side top, in front of the CPU, is an exhaust. The one on side bottom, in front of the graphic card is intake. So you're saying I should reverse this? Also I thought that, having the side fan blowing air on the graphic card, will cool it down, in addition to the front intake.
you would probably see the most benefit from having both side fans as intake fans. it's probably very inefficient to have an exhaust and an intake next to each other, rather than having the cooler air from the intake circulate and cool components before leaving via an exhaust some of it will be extracted too rapidly. the general idea of case fans is to have an airflow system that promotes the intake of cooler air from outside the case, blows that across components to transfer heat before being extracted by an exhaust fan/s. as long as there is good ventilation/adequate exhaust then the more intake fans the better.
