    He is correct. Fans are used to create an airflow inside the case to remove the heat. You want the incoming air to be filtered to reduce the amount of dust entering your case. On my cases, the fans in front bring cooler air in from outside, the ones in back blow out to remove the hot air, creating an airflow.

    Most tower style cases follow these rules...

    Top of the case = Out
    Side panel of case = In
    Front panel of case = In (some have filters)
    Rear panel of case = Out
