A back fan should be mounted to push air out from the case.

Without looking at the sticker on the motor, virtually every fan has arrows molded into the plastic frame on the side. One points around the frame, and that's the direction of blade turning when the fan is wired properly to power supply. The other points through the frame, and that's the direction of air flow.
