Setup and Installation
This fan is designed as a replacement part for specific Beelink L55 series mini PCs. Installation typically involves replacing an existing fan.
Tools Required:

Installation Steps:

- Access Internal Components: Carefully open the mini PC casing. Refer to your Beelink mini PC's specific service manual for instructions on how to safely open the enclosure.
- Locate and Disconnect Old Fan: Identify the existing fan. Gently disconnect its power cable from the motherboard. Note the orientation and routing of the cable.
- Remove Old Fan: Unscrew any mounting screws holding the old fan in place and carefully remove it.
- Install New Fan: Position the new Generic Mini PC Fan in the same location as the old one. Secure it with the mounting screws.

Operation
Once correctly installed, the Mini PC Fan operates automatically, controlled by your mini PC's system to maintain optimal internal temperatures. It will adjust its speed based on the thermal load of the system.
Normal Operation:
- The fan should spin quietly, producing a consistent airflow.
- The mini PC's internal temperature should remain within normal operating ranges.
If you notice unusual noises or if the PC reports high temperatures, refer to the Troubleshooting section.
Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your fan and mini PC.
Cleaning:
- Frequency: Depending on your environment, it is recommended to clean the fan every 6-12 months.
- Procedure:
- Power off and disconnect the mini PC from all power sources.
- Carefully open the mini PC casing to access the fan.
- Use compressed air to gently blow dust away from the fan blades and heatsink fins. Hold the fan blades to prevent them from spinning rapidly during cleaning, which can damage the bearings.
- Avoid using liquid cleaners directly on the fan or internal components.
- Reassemble the mini PC.
Inspection:
- Periodically inspect the fan for any signs of physical damage, loose connections, or excessive wear on the blades.
- Ensure the fan spins freely without obstruction.
