Default Re: Silverstone's Pushes Positive Pressure Cooling, SFX Small Power Supplies

The white arrows are the air intake/exhaust from the case through the leaks
In the case of positive air pressure, any leak will see air leaving the case.
Opposite, in the case of negative pressure, any opening will get air inside (and dust).

You need to be as close to balanced as possible for good airflow. A slight positive is better to keep dust out (if you have intake filters).
