The Fan/Heat sink is a crucial part of the computers components. This is responsible for cooling down the computers components (Mainly the processor, as this gets most hot) This is done through heat exchange. A separate fan is often given to the processor as they can go as hot as 90c. The fan is the fan, and the metal is the heat sink. The cooling fan is mounted to the processor whilst the heat skin is placed on top, cooling the components quickly.
