    It's essential that the fan area always be kept clean and unobstructed so the device can cool. Some of the more resource intensive graphics cards also have a built in fan to prevent them from over-heating

    The power supply produces heat, the fan helps it cool off. It can also help cool the entire system depending on how it's set up.
