4. Setup and Installation
4.1 Fan Airflow Direction
For optimal cooling, ensure the fan is installed with the correct airflow direction. For normal airflow design fans, the blade side acts as intakes, and the frame side acts as exhausts. Install fans according to your case's airflow requirements.

4.2 Connecting PWM for Fan Speed Control
- Locate the 4-pin PWM fan power connector on your fan cable.
- Connect this 4-pin PWM connector to an available 4-pin fan header on your motherboard (e.g., CHA_FAN, CPU_FAN).
- If connecting multiple fans, use the provided PWM sharing connector to daisy-chain additional fans for synchronized speed control. Connect the additional fan's PWM connector to the sharing header.
4.3 Connecting ARGB for Lighting Control
The fan supports 5V 3-pin Addressable RGB (ARGB) lighting. Do not connect to a 12V 4-pin RGB header, as this will damage the fan.
- Locate the 3-pin 5V ARGB connector on your fan cable.
- Connect this 3-pin ARGB connector to an available +5V ARGB header on your motherboard.
- To synchronize the ARGB light effect across multiple fans, use the provided ARGB sharing connector to daisy-chain additional fans. Connect the additional fan's ARGB connector to the sharing header.
- Note: Do not connect more than 6 ARGB fans of the same specification in series to avoid overloading the motherboard header.
4.4 Mounting the Fan
- Position the fan in the desired location within your PC case, on a CPU cooler, or on a water cooling radiator, ensuring the correct airflow direction.
- Align the fan's screw holes with the mounting points.
- Use the included screws to secure the fan. Tighten screws evenly to prevent warping.

5. Operating Instructions
Once installed and connected, the Thermalright TL-C12C-X28-S X3 fan operates automatically:
- Fan Speed Control (PWM): The fan speed is automatically regulated by your motherboard based on system temperature. You can typically adjust fan curves and profiles through your motherboard's BIOS/UEFI settings or dedicated software.
- ARGB Lighting Control: The ARGB lighting effects can be controlled and synchronized via your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). Refer to your motherboard manual for specific instructions on ARGB software usage.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your fan:
- Cleaning: Periodically clean the fan blades and frame to remove dust buildup. Use compressed air or a soft, dry cloth. Ensure the system is powered off before cleaning.
- Inspection: Check cables for any signs of wear or damage. Ensure all connections remain secure.
- Bearing: The S-FDB bearing is designed for long-term, maintenance-free operation. Do not attempt to disassemble the fan.
7. Troubleshooting
If you encounter issues with your fan, refer to the following common solutions:
- Fan Not Spinning:
- Ensure the 4-pin PWM connector is securely plugged into the motherboard fan header.
- Check your motherboard's BIOS/UEFI settings to ensure the fan header is enabled and configured correctly.
- Test the fan on a different fan header or with a fan controller if available.
- ARGB Lights Not Working/Incorrect Colors:
- Verify the 3-pin 5V ARGB connector is securely plugged into a +5V ARGB header on your motherboard. Ensure it is not connected to a 12V 4-pin RGB header.
- Check your motherboard's ARGB software for correct settings and synchronization.
- Ensure no more than 6 fans are daisy-chained to a single ARGB header.
- Excessive Noise:
- Ensure the fan is securely mounted and not vibrating against the case or other components.
- Check for any cables or obstructions interfering with the fan blades.
- Adjust fan speed settings in your motherboard's BIOS/UEFI or software to a lower RPM if noise is a concern and temperatures allow.
