Setup and Installation
Follow these steps to properly install your Thermalright TL-S12W-S fans into your PC system.
1. Physical Installation
- Determine Airflow Direction: Select the fan installation direction based on your PC case's desired airflow. Fans typically have an arrow indicating airflow direction.
- Mount the Fan: Position the fan in the desired location (e.g., rear exhaust, front intake, top exhaust). Use the provided screws to secure the fan to the PC case. Ensure a snug fit without overtightening.

2. Wiring for ARGB Lighting
- Connect ARGB Headers: Each fan has a 3-pin ARGB header. Connect these headers in series using the provided ARGB sync cables. Ensure the arrows on the connectors align to maintain correct polarity.
- Connect to Motherboard: Plug the final 3-pin ARGB cable into your motherboard's +5V ARGB header. The TL-S12 series supports connecting up to 4 fans to a single motherboard 3-pin ARGB socket, while the TL-S12S series supports up to 3.

3. Wiring for Fan Speed Control (PWM)
- Connect PWM Headers: Connect the 4-pin PWM headers of the fans in series using the provided PWM sync cables.
- Connect to Motherboard: Plug the final 4-pin PWM cable into your motherboard's fan header. This allows the motherboard to control the fan speed automatically based on system temperature. A maximum of 3 fans can be connected to a single motherboard fan socket.

Operating Instructions
Once installed and connected, your Thermalright TL-S12W-S fans will operate as follows:
- PWM Fan Speed Control: The fans' speed is automatically regulated by your motherboard via the 4-pin PWM connection. This ensures optimal cooling performance by adjusting fan speed based on CPU or system temperature. You can typically configure fan curves in your motherboard's BIOS/UEFI settings or through manufacturer-provided software.
- ARGB Lighting Control: The ARGB lighting effect is controlled by your motherboard's +5V ARGB header. You can customize lighting patterns, colors, and synchronization through your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync). Ensure your motherboard software is up-to-date for the best experience.

Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your fans.
- Dust Cleaning: Periodically clean dust from the fan blades and frame using compressed air or a soft brush. Ensure the PC is powered off and unplugged before cleaning.
- Bearing: 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.
- Cable Management: Ensure all cables are neatly routed and secured to prevent interference with fan blades or other components, which could lead to damage or noise.
Troubleshooting
If you encounter issues with your Thermalright TL-S12W-S fans, refer to the following common troubleshooting steps:
- Fan Not Spinning:
- Check if the 4-pin PWM cable is securely connected to the motherboard fan header.
- Verify that the motherboard's fan header is enabled in BIOS/UEFI settings.
- Ensure the power supply is functioning correctly.
- ARGB Lighting Not Working:
- Confirm the 3-pin ARGB cable is correctly connected to the motherboard's +5V ARGB header, with arrows aligned.
- Check your motherboard's RGB software to ensure lighting is enabled and configured.
- Ensure the motherboard's ARGB header is providing power.
- Excessive Noise:
- Verify that all mounting screws are tightened properly.
- Check for any cables or obstructions touching the fan blades.
- Clean any dust buildup on the fan blades.
- Ensure the fan is not running at excessively high RPMs; adjust fan curves in BIOS/UEFI if necessary.
