Second-Gen Performance

Level up your airflow with the Lian Li UNI FAN SL-INF 140 series of PWM fans. This 140 mm fan utilises second-generation cooling technology, that sees a 10% performance over the previous SL140 model. Additionally, each fan has 40 ARGB LEDs embedded in the frame and central hub along with mirror integration. With zero compromises on thermal capacity and lighting brightness, the SL-INF 140 is an excellent addition to your gaming PC.

The Lian Li UNI FAN SL-INF 140 utilises second-generation cooling technology, to achieve its performance boost. Its seven-blade fan design has been optimised for faster speeds, higher airflow and static air pressure, along with quieter operation. At its top speed, the SL-INF 140 only produces 28 dBA noise levels. This fan will efficiently cool your gaming PC with a maximum static pressure of 2.88 mmH2O and airflow of 72.7 CFM.

Additionally, as PWM fans, the operational speed can be adjusted to suit workloads. Thanks to L-Connect 3 software, you have the option to implement the Start/Stop mode. When the CPU or GPU are running below 50 °C, the fans completely stop. When in operation, speeds can be adjusted from 200 RPM to 1,600 RPM, providing you with immense control.

ARGB Lighting

Each Lian Li UNI FAN SL-INF 140 is equipped with 40 ARGB LEDs, embedded in the frame and central hub. Maximising brightness, these LEDs have been paired with an infinity mirror to create an incredible lighting effect. The infinity mirror is layered, with 0.5 mm breaks adding a definition that can be seen from any angle. The 3D effect and geometric frame shape culminate in a bold aesthetic that works in every gaming PC. Plus, the aluminium trim reflects the effect further, meaning the lighting is visible on both edges and sides of the frame.

Improved Features

Previously, Lian Li ARGB PWM fans used separate cables for lighting and power. Innovating the design, Lian Li UNI FAN SL-INF 140 utilises a single cable with a 7-pin connector that supplies both power and light. This connects to the new UNI HUB, available with the SL-INF 120 triple packs, or separately (LULI-032). Alternatively, the single-pack models include a split cable with both a 4-pin PWM and 3-pin ARGB header, which can connect directly to the motherboard.

What's more, the daisy-chaining feature has been improved too. The Lian Li UNI FAN SL-INF 140's connector key, which slots into a second fan's frame, can be easily removed. Simply twist 90 ° and pull from the frame. This increases the SL-INF 140's compatibility with radiators and leaves no protruding parts for a cleaner aesthetic. Should the need for the key arise, then it can be re-installed just as easily.

Additionally, the Lian Li UNI FAN SL-INF 140 sees an improvement in cable management. The cable module is smaller than on previous models and is now located centrally on the fan frame edge. Plus, it can be orientated in several ways to optimise cable efficiency according to your build.

UNI HUB and L-Connect 3

The UNI HUB controller has been optimised for cohesive support. This hub now features two 3-pin ARGB SM ports, designed specifically to support other Lian Li ARGB devices, such as the LEDs on the Galahad AiO pump. This is in addition to the four ports for supporting up to sixteen UNI FANs, in four clusters of four.

Lighting and fan control are achieved through Lian Li's updated L-Connect 3 software or your motherboard software. Each cluster can be assigned a fan speed or set to specific modes, to best suit your needs. When it comes to lighting, there are over 30 effects to experiment with and the whole spectrum of 16.8 million colours. Effects can be assigned to the fan's centre only, fan edge, or a combination of the two. With such amazing flexibility, the Lian Li UNI FAN SL-INF 140 can be home to some amazing light shows.
