A fan is a device that creates airflow to cool electronic components. It is used to reduce the temperature inside the system unit and prevent overheating.
Functions:
- Cooling: Fans remove heat from heated components such as processors, video cards, and power supplies. - Airflow: Create air circulation inside the computer case for efficient cooling.
Types of fans:
- CPU Fan: Specifically designed to cool the CPU and usually plugs into the CPU Fan connector on the motherboard.
- Chassis (Cha) Fan: Case fans that circulate air inside the computer case.
- Sys Fan: System fans that can be used to cool various components such as the chipset or hard disk drive. - Pwr Fan: Rarely seen, used to cool the power supply.
Characteristics:
- Size: The larger the diameter of the fan, the better it cools.
- Rotation Speed: Higher speeds provide stronger airflow.
- Connector Type: Fans can have different types of connectors to connect to the motherboard, such as 3-pin or 4-pin connectors.
