Setup
1. Unpacking and Component Check
Carefully remove the fans and accessories from the packaging. Verify that all components are present:
- Thermalright TL-M12QR 120mm Fans (3 units)
- Connecting Cable (1 unit)
- Mounting Screws
2. Fan Installation
The TL-M12QR fans feature a snap-on splicing structure for easy installation and disassembly. This modular design allows multiple fans to be connected directly to each other, reducing cable clutter.

- Align the first fan with the desired mounting location in your PC case or radiator. Secure it using the provided mounting screws.
- To connect additional fans, align the side of the next fan with the installed fan. Gently push them together until they snap securely into place. The wireless splicing mechanism will connect the power and ARGB signals between the fans.
- Repeat for any additional fans in the cluster.
3. Cable Management
The daisy-chain design significantly simplifies cable management, requiring only one main cable connection for a cluster of fans.

- Connect the 4-pin PWM cable from the fan cluster to an available 4-pin fan header on your motherboard. This allows for automatic speed control based on system temperature.
- Connect the 3-pin 5V ARGB cable from the fan cluster to an available 3-pin 5V Addressable RGB header on your motherboard. This enables synchronization and control of the lighting effects.
- Ensure all connections are secure.
Operating
1. Fan Speed Control
The Thermalright TL-M12QR fans utilize a 4-pin PWM (Pulse Width Modulation) connection for precise speed control. When connected to a compatible motherboard header, the fan speed will automatically adjust based on the CPU or system temperature, optimizing cooling performance and noise levels.
- You can configure fan curves and control speeds through your motherboard's BIOS/UEFI settings or dedicated software provided by your motherboard manufacturer.
- The fans operate at a maximum speed of 1500 RPM, providing high airflow for effective cooling.

2. ARGB Lighting Control
The fans feature unique ARGB infinity mirror lighting effects and bezel ARGB lines. These can be synchronized with your motherboard's ARGB software for a cohesive lighting scheme.

- Ensure the 3-pin 5V ARGB cable is correctly connected to your motherboard's ARGB header.
- Use your motherboard's ARGB control software (e.g., ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync, ASRock Polychrome Sync) to customize lighting patterns, colors, and synchronization with other ARGB components.
- The dual infinity mirror design creates a depth effect, enhancing the visual appeal of your PC build.

Maintenance
1. Bearing Care
The Thermalright TL-M12QR fans are equipped with high-durability S-FDB (Fluid Dynamic Bearing) technology. These bearings are designed for low-friction and low-noise operation, providing a long service life without requiring maintenance. Do not attempt to disassemble the fan for bearing maintenance.

2. Cleaning
Regular cleaning helps maintain optimal airflow and performance.
- Power off your PC and disconnect it from the power source before cleaning.
- Use a can of compressed air to gently blow away dust from the fan blades and frame. Hold the fan blades to prevent them from spinning rapidly during cleaning, which can damage the bearings.
- For stubborn dirt, use a soft, dry cloth to wipe the fan blades and frame. Avoid using liquid cleaners directly on the fans.
Troubleshooting
1. Fans Not Spinning
- Check Power Connection: Ensure the 4-pin PWM cable is securely connected to a functional fan header on your motherboard.
- BIOS Settings: Verify that the fan header is enabled in your motherboard's BIOS/UEFI settings and that the fan curve is configured correctly (e.g., not set to 0 RPM at low temperatures if you expect constant spin).
- Daisy-Chain Integrity: If multiple fans are daisy-chained, ensure all fans are properly snapped together to establish electrical contact.
2. ARGB Lights Not Working or Incorrect Colors
- Check ARGB Connection: Ensure the 3-pin 5V ARGB cable is securely connected to a 3-pin 5V Addressable RGB header on your motherboard. (Note: Do NOT connect to a 4-pin 12V RGB header, as this can damage the LEDs).
- Motherboard Software: Use your motherboard's ARGB control software to verify settings and apply desired lighting effects. Ensure the software recognizes the ARGB device.
- Daisy-Chain Integrity: For daisy-chained fans, confirm that each fan is correctly connected to the next to ensure the ARGB signal propagates through the chain. If one fan in the chain is not lighting up, try swapping its position or testing it individually.
3. Excessive Noise
- Check Mounting: Ensure fans are securely mounted and not vibrating against the PC case or other components. The fans include silicone rubber pads for vibration damping.
- Dust Buildup: Clean the fans as described in the Maintenance section to remove any dust that might be causing imbalance or increased noise.
- Fan Speed: Adjust fan speeds through your motherboard's BIOS/UEFI or software. Higher RPMs naturally produce more noise.
