  1. It's a good idea to check for airflow from your graphics card (if using a desktop) or the side/back of the case (if using a laptop). you should definitely notice hot air being blown out against the back of your hand.

    Something else you can do, if you've an older system, is to turn your graphics settings DOWN. Turn off the fancy rendering options such as shadows and reflection effects. This will decrease the load on the graphics card, so that it doesn't heat up as badly.
