    Default Rear Exhaust Fan Question

    If the idea is to get as much air OUT of the pc as possible....then why do the back's of all pc's have holes where the rear fan goes?? Wouldn't those holes hold back a lot of air from leaving? Why isn't it just one big hole with maybe a light, rounded gate mounted on the back?

    Not exactly, the idea is to bring cool outside air in an exhaust the hot out. Yes i believe the holes do hold back air, but i think its more of an aesthetic/ maybe safety feature.

    Safety feature so dumb ****s won't stick their fingers in a moving fan. Removing the holes would make a minimal difference in airflow. As James said, the idea is the move cool air through the case.

    what holes are we talking about here...the tiny extra holes surrounding the fan port?
    Anyway, they are ventilation for cross air flow, you want the hot air to escape the case as fast as possible. One single exhaust port is not enough.

    oh, you were talking about the style of fan grill. I thought you were talking about the extra vent holes surrounding at the back of the case.
    Wired fan guard or bigger holes are better than small one. Most high-end cases don't use honeycomb style fan port.

    The mesh over the exhaust fan is there to prevent physical access to the fan and for EMF shielding. Cutting that area out and replacing it with a simple wire grill should increase air flow (and was once a very common mod).
