120 mm ARGB PWM Wireless Reverse-Blade -tuuletin Lian Li UNI FAN TL (langaton, PWM, Reverse Blade)

Lian Li UNI FAN TL is a 120mm wireless ARGB PWM reverse blade fan engineered for use in PC cases and on radiators. The fan combines addressable RGB lighting with PWM speed control and a reverse blade geometry intended to improve airflow patterns while keeping airborne noise low. The wireless connection reduces cable clutter and simplifies multi-fan setups, while the 120mm size fits standard mounting points for system and cooling builds.

Advantages

The fan integrates customizable addressable RGB lighting with a compact control interface to let builders synchronize illumination without extensive cabling. PWM control enables automatic speed adjustments based on temperature, delivering balance between cooling performance and acoustic profile. The reverse blade design is intended to optimize airflow direction and reduce turbulence, which can lower perceived noise at comparable fan speeds. The wireless functionality reduces the need for multiple wired ARGB or fan headers, improving cable management and installation flexibility.

Suitable for

• Case cooling in mid-tower and full-tower PC builds
• Radiator fans for AIO or custom liquid cooling
• Multi-fan lighting setups where reduced cable routing is preferred
• Systems requiring PWM-based speed control for temperature-dependent operation

Key specifications

• Size: 120 mm standard mounting diameter
• Lighting: Addressable RGB (ARGB) individually controllable LEDs
• Control: PWM speed control for dynamic fan RPM adjustment
• Blade design: Reverse blade geometry for modified airflow and reduced turbulence
• Connectivity: Wireless control for lighting and fan coordination to minimize cables
• Compatibility: Designed for standard 120 mm fan mounts in cases and radiators

How to use

Mount the 120mm fan to the case or radiator using the standard four mounting holes, ensuring the airflow direction aligns with the intended cooling pathway. Connect the wireless hub or receiver according to the included instructions to enable ARGB synchronization and PWM control; the hub manages communication between multiple fans and the system controls. Configure PWM settings via the motherboard or fan controller to set temperature-based profiles or fixed speeds. Use the ARGB utility or the hub interface to customize lighting sequences and color patterns.

Recommendations

Place fans to create a clear airflow path through the chassis: intake at the front/bottom and exhaust at the top/rear for most tower configurations. When installing as radiator fans, ensure the reverse blade orientation supports the desired push or pull setup. For quieter operation, enable PWM curves that keep idle RPMs low and ramp up under load. Keep the wireless hub accessible and free from metal obstructions for reliable signal transmission.
