Now, don't get me wrong, the addition of an outtake fan can help you shape the kind of airflow you want but, even with its absence, the air simply won't "stay in the case and heat up..."
Actually, that is incorrect. Conservation of mass states that matter cannot be created nor destroyed. Pressure is the term used for various amounts of fluids (air/liquid) per unit. With more intake, he could have greater pressure built up in his case. Having a better or bigger exhaust fan in that case would be necessary to move out the greater amount of air.
