- Quality S-FDB Bearings: Ensures minimal noise and maximum cooling performance, extending fan life.
- Excellent ARGB Lighting: High-brightness LED atomizing fan blades with up to 17 modes, controllable and synchronizable via motherboard ARGB port.
- Versatile Application: Suitable for use as a case fan, with CPU coolers, or radiators for enhanced thermal management.
2. What's in the Box
- CPU Fan (Thermalright TL-C12CW-S X3)
- Mounting Screws (for case fan mounting)
- Vibration-free Mounts (for case fan mounting)
Note: The quantity of fans and accessories may vary based on the product package (e.g., 3 Quantities).
3. Installation Guide
3.1 Airflow Direction
Before installation, identify the airflow direction of the fan. The side with the fan blades visible (without the frame supports) is typically the intake side, pushing air in. The side with the frame supports is typically the exhaust side, where air exits.

3.2 Mounting with Vibration-Free Mounts
- Insert the thin end of a vibration-free mount through a fan mounting hole on your PC case.
- Pull the mount through until the wider part secures it against the case.
- Align the fan with the mounting holes and push the remaining end of the mount through the corresponding fan hole.
- Pull the mount firmly to secure the fan in place, ensuring it is snug and vibration-free. Repeat for all four corners.

3.3 Mounting with Screws
- Align the fan with the desired mounting location on your PC case.
- Insert a mounting screw through the fan's mounting hole and into the case.
- Use a screwdriver to gently tighten the screw. Do not overtighten to avoid damaging the fan or case.
- Repeat for all four corners to securely mount the fan.
3.4 Connecting the Fan
Connect the 4-pin PWM fan cable from the Thermalright TL-C12CW-S X3 fan to an available 4-pin fan header on your motherboard. For ARGB lighting, connect the 3-pin ARGB cable to a compatible 5V ARGB header on your motherboard. Ensure correct orientation for both connections.

4. Operating Instructions
4.1 Fan Speed Control (PWM)
The fan's 4-pin PWM connector allows your motherboard to automatically control the fan speed based on system temperature. This ensures optimal cooling performance when needed and quieter operation during lighter loads. You can typically configure fan curves in your motherboard's BIOS/UEFI settings or through manufacturer-provided software.
4.2 ARGB Lighting Control
The Thermalright TL-C12CW-S X3 features Addressable RGB (ARGB) lighting with up to 17 different lighting modes. To control and synchronize the lighting effects, connect the 3-pin ARGB cable to a compatible 5V ARGB header on your motherboard. Lighting can then be managed using your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync).

5. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your Thermalright TL-C12CW-S X3 fans.
- Cleaning: Periodically clean the fan blades and frame to remove dust buildup. Use compressed air or a soft brush. Ensure the fan is powered off before cleaning.
- Cable Management: Ensure all cables are neatly routed and secured to prevent interference with fan blades or other components.
- Inspection: Occasionally inspect the fan for any signs of wear, damage, or unusual noise.
6. Troubleshooting
- Fan Not Spinning:
- Check if the 4-pin PWM cable is securely connected to the motherboard fan header.
- Verify that the fan header is enabled in the motherboard's BIOS/UEFI settings.
- Ensure the power supply is functioning correctly.
- ARGB Lights Not Working/Synchronizing:
- Confirm the 3-pin ARGB cable is correctly connected to a 5V ARGB header on the motherboard.
- Check your motherboard's ARGB software for proper configuration and synchronization settings.
- Ensure the ARGB header is enabled in the motherboard's BIOS/UEFI.
- Excessive Noise:
- Check for any cables or obstructions hitting the fan blades.
- Ensure the fan is securely mounted and not vibrating against the case.
- Clean any dust buildup on the fan blades.
- Adjust fan speed settings in BIOS/UEFI or software to a lower RPM if noise is a concern and temperatures allow.
