What is the purpose of a cooling fan in a computer?

The purpose of a cooling fan in a computer is to dissipate heat generated by the various components within the computer system. Computers generate heat when they are in use due to the functioning of the CPU (Central Processing Unit), GPU (Graphics Processing Unit), power supply unit, and other components. If this heat is not properly managed, it can lead to overheating, which can cause performance issues and potentially damage the hardware. The cooling fan works by blowing cool air onto these components, transferring the heat away from them, and maintaining a suitable operating temperature for the computer.
