5. 사용 설명서
The Wathai blower fan operates by drawing air from one side and expelling it from the other, providing focused airflow. Its 4-pin PWM functionality allows for dynamic speed adjustment based on system requirements or manual control.
PWM 속도 제어:
The fan speed is controlled by the voltage signal on the blue PWM pin. When connected to a compatible 4-pin fan header on a motherboard or fan controller, the system can automatically adjust the fan speed based on temperature readings. This allows for efficient cooling when needed and quieter operation during lighter loads.

6. 유지관리
Regular maintenance ensures optimal performance and extends the lifespan of your blower fan.
- 청소: Periodically inspect the fan blades and housing for dust accumulation. Use compressed air or a soft brush to gently remove dust. Ensure the fan is powered off and disconnected before cleaning.
- 점검: Check for any obstructions around the fan's intake and exhaust ports. Ensure cables are not interfering with fan operation.
- 베어링 관리: The dual ball bearings are designed for long-term, maintenance-free operation. Avoid applying lubricants unless specifically instructed by the manufacturer.
7. 문제 해결
If you encounter issues with your Wathai blower fan, refer to the following common problems and solutions:
- 팬이 회전하지 않음:
- Ensure the 4-pin connector is securely plugged into a powered fan header.
- 전원 공급장치가 올바르게 작동하는지 확인하세요.
- Check BIOS/UEFI settings or fan control software to ensure the fan is enabled and not set to 0 RPM at low temperatures.
- 과도한 소음:
- Inspect for any obstructions (cables, debris) hitting the fan blades.
- Ensure the fan is securely mounted and not vibrating against the chassis.
- If using PWM, adjust the fan speed to a lower percentage to reduce noise, if cooling requirements allow.
- 공기 흐름이 부족합니다.
- Check for dust buildup on fan blades or in the housing and clean as described in the Maintenance section.
- Verify the fan's airflow direction is appropriate for your cooling setup.
- Ensure the fan is operating at an adequate speed via PWM control.
