Answer:
The system unit, also known as the "tower" or "chassis", is the major part of a desktop computer. This includes the motherboard, CPU, RAM, and others. The system unit also includes the case that contains the internal components of the computer.
Explanation:
A computer fan is any fan inside or attached to a computer case used for active cooling. The fan is used to draw cold air into the case from the outside, to expel hot air from the inside, and to move air into the heat sink to cool a particular part. Both axial and centrifugal (blower/squirrel-cage) fans are used in computers. Computer fans usually come in standard sizes such as 92 mm, 120 mm (the most common), 140 mm and even 200–220 mm. Computer fans are operated and controlled using 3-pin or 4-pin fan connectors.
