Laptops intakes are usually the bottom, so it will be an intake. Keep this unobstructed when playing, keep good airflow by using your laptop on a desk or hard flat surface but not on your lap (contrary to the name!), and at the hinge will be your exhaust. Easily recognisable by warm air blowing from it. A cooling pad will help if you are worried with heat or noise. But first try blowing out the fan with some compressed air to remove any built up dust and crap. Temps aren't worrying yet though.
