5. Setup & Installation
Follow these steps to properly install your Thermalright TL-C12B-S V3 fans in your computer case or on a cooler.
5.1. Identify Fan Airflow Direction
The fan blades indicate the intake side, and the frame side indicates the exhaust. Ensure correct orientation for optimal airflow within your case.

5.2. Connect PWM Power Cable
Connect the 4-pin PWM fan power connector to an available 4-pin FAN socket on your motherboard. If installing multiple fans, daisy-chain them using the provided connectors. The total number of fans connected to a single motherboard header should be less than three to ensure stable power delivery and speed synchronization.

5.3. Connect ARGB Lighting Cable
For ARGB lighting functionality, connect the 3-pin 5V addressable RGB connector to a compatible +5V 3-pin ARGB header on your motherboard. Daisy-chain additional ARGB components to synchronize lighting effects. The total number of ARGB components connected to a single motherboard header should be less than five to prevent overloading.

6. Operating Instructions
Once installed and connected, the Thermalright TL-C12B-S V3 fans will operate automatically.
- Fan Speed Control: The 4-pin PWM connection allows your motherboard to automatically adjust fan speed based on CPU or system temperature, ensuring optimal cooling and noise levels. You can typically configure fan curves in your motherboard's BIOS/UEFI settings or through manufacturer-provided software.
- ARGB Lighting Control: The 3-pin 5V ARGB connection enables control of the fan's lighting effects through your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). This allows for synchronization with other ARGB components and customization of colors and patterns.
7. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your fans.
- Dust Cleaning: Periodically clean dust from the fan blades and frame using compressed air or a soft brush. Ensure the computer is powered off and unplugged before cleaning.
- Bearing Maintenance: The S-FDB bearing is designed to be maintenance-free. Do not attempt to disassemble the fan for lubrication or repair, as this may void the warranty and damage the product.
- Cable Inspection: Occasionally check that all power and ARGB cables are securely connected and free from damage.
8. Troubleshooting
If you encounter issues with your Thermalright TL-C12B-S V3 fans, refer to the following common solutions:
- Fan Not Spinning:
- Check if the 4-pin PWM power cable is securely connected to the motherboard's FAN header.
- Ensure the motherboard's FAN header is enabled in BIOS/UEFI settings.
- Verify that the fan speed control software or BIOS settings are not set to 0 RPM or a very low threshold.
- ARGB Lighting Not Working/Incorrect:
- Confirm the 3-pin 5V ARGB cable is correctly connected to a compatible +5V 3-pin ARGB header on the motherboard. Do not connect to a 12V RGB header, as this will damage the LEDs.
- Check your motherboard's ARGB control software for proper configuration and enabled lighting effects.
- Ensure the total number of ARGB components connected to a single header does not exceed the motherboard's specified limit.
- Excessive Noise:
- Verify that the fan is securely mounted and the mounting screws are tightened.
- Check for any cables or obstructions touching the fan blades.
- Clean any dust buildup on 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.
