5. Setup and Installation
Follow these steps to properly install your FHS 80X fan:
- Prepare the System: Power off your computer or server and disconnect it from the power source. Open the chassis to access the fan mounting location.
- Mount the Fan: Position the fan in the desired location, ensuring correct airflow direction. Use the provided mounting screws to secure the fan to the chassis. The fan grill should be placed on the intake side to protect against foreign objects.
- Connect the Power: Locate an available 4-pin PWM fan header on your motherboard or fan controller. Connect the fan's 4-pin connector to this header. Ensure the connector is fully seated.

6. Operating Instructions
The FHS 80X fan utilizes Pulse Width Modulation (PWM) for speed control, allowing for dynamic adjustment based on system temperature or user preference.
- Automatic Control: When connected to a PWM-compatible motherboard header, the fan speed will automatically adjust based on the system's thermal load, as configured in the BIOS/UEFI settings.
- Manual Control: Many motherboards and fan controllers offer software utilities to manually set fan curves or fixed speeds. Refer to your motherboard or controller manual for specific instructions.
- Speed Range: The fan operates within a speed range of 2,000 RPM to 10,000 RPM, providing significant cooling capacity.

7. Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your fan.
- Cleaning: Periodically clean dust accumulation from the fan blades and grill using compressed air or a soft brush. Ensure the system is powered off before cleaning.
- Inspection: Check for any obstructions around the fan or damage to the blades or wiring.
- Bearing Care: The dual ball bearings are designed for long-term operation and typically do not require lubrication.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan not spinning | No power, loose connection, faulty fan header. | Check power connections. Ensure 4-pin connector is fully seated. Try a different fan header. |
| Fan spinning too slow/fast | Incorrect BIOS/UEFI settings, fan controller issue. | Adjust fan speed settings in BIOS/UEFI or fan control software. Ensure PWM header is used. |
| Excessive noise | Dust accumulation, loose mounting, bearing issue. | Clean fan blades and grill. Ensure fan is securely mounted. If noise persists, consider replacement. Note: This is a high-performance fan and may generate significant noise at high RPMs. |
