3. Setup and Installation
3.1 Wireless Splicing
The TL-M12QW X3 fans feature a unique wireless splicing design, allowing multiple fans to connect directly to each other without individual cables for power and ARGB signals. This simplifies cable management significantly.

To splice fans:
- Align the snap-on connectors on the sides of the fans.
- Gently push the fans together until they click into place, ensuring a secure connection.
- The modular control line will then provide power and ARGB signals to the entire spliced unit.

3.2 Fan Installation and Disassembly
The fans are designed for simple installation and removal.

Installation:
- Position the fan unit in your desired location (case or radiator).
- Secure the fan using appropriate screws (not explicitly shown but implied by standard fan installation).
Disassembly:
- Unscrew the fan unit from its mounting.
- Gently pull the fans apart from their spliced connection.
3.3 Cable Connections
Despite wireless splicing between fans, a main control line is required to connect the fan unit to your motherboard or ARGB controller.


Connect the following cables from the modular control line to your motherboard or controller:
- 4-Pin PWM Cable: Connect this to a 4-pin fan header on your motherboard for fan speed control.
- 3-Pin 5V ARGB Cable: Connect this to a 5V-3pin Addressable RGB header on your motherboard or a compatible ARGB controller for lighting synchronization. Do NOT connect to a 12V RGB header, as this will damage the LEDs.
4. Operating Instructions
4.1 Fan Speed Control
The fan speed can be controlled via the 4-pin PWM connection. This allows your motherboard or fan controller to dynamically adjust the fan speed (450-2000 RPM) based on system temperature, optimizing for either performance or silence.

4.2 ARGB Sync Lighting
The TL-M12QW X3 fans feature Addressable RGB (ARGB) lighting with infinity mirror effects on both sides. This allows for a wide range of customizable lighting patterns and synchronization with other ARGB components in your system.

To control the ARGB lighting:
- Ensure the 3-pin 5V ARGB cable is correctly connected to a compatible ARGB header on your motherboard or an ARGB controller.
- Use your motherboard's RGB software (e.g., ASUS Aura Sync, Gigabyte RGB Fusion, MSI Mystic Light Sync, ASRock Polychrome Sync) or your dedicated ARGB controller software to customize lighting effects, colors, and synchronization.
5. Maintenance
5.1 Cleaning
To maintain optimal performance and aesthetics, periodically clean your fans:
- Power off your computer and disconnect the power supply.
- Use compressed air to remove dust from the fan blades and frame.
- For stubborn dirt, gently wipe the blades with a soft, dry cloth. Avoid using liquids or harsh chemicals.
5.2 Bearing Information
The TL-M12QW X3 fans utilize high-precision S-FDB (Fluid Dynamic Bearings) which are designed for long durability and are maintenance-free. There is no need to add lubricant.

Important: Do not disassemble the fan. Self-disassembly may result in loss of functionality and void the product warranty.
6. Troubleshooting
- Fan Not Spinning:
Ensure the 4-pin PWM cable is securely connected to a fan header on your motherboard. Check BIOS/UEFI settings or fan control software to ensure the fan header is enabled and receiving power. - ARGB Lights Not Working/Incorrect Colors:
Verify the 3-pin 5V ARGB cable is correctly connected to a 5V-3pin ARGB header (not 12V RGB). Check your motherboard's RGB software or ARGB controller settings. Ensure all spliced fans are properly connected to each other. - Excessive Noise:
Check for any obstructions (cables, debris) hitting the fan blades. Ensure the fan is securely mounted and the silicone corner pads are properly seated to reduce vibration. If noise persists, it may indicate a bearing issue (though unlikely with FDB bearings) or an issue with fan balance. - Fans Not Splicing Correctly:
Ensure the snap-on connectors are aligned correctly and pushed firmly until they click. Check for any bent pins or debris in the connectors.
7. User Tips
- When planning your build, consider the direction of airflow (intake vs. exhaust) for optimal cooling. The fan's design allows for clear air intake/outlet visualization.
- Utilize the wireless splicing feature to minimize cable clutter in your PC case, leading to a cleaner build and improved airflow.
- Experiment with different ARGB lighting patterns and synchronization options through your motherboard software to personalize your system's aesthetics.
- Regularly check for dust accumulation, especially if your PC operates in a dusty environment, to maintain fan efficiency and longevity.
