LIAN LI Launches the Uni Fan SL-INF 140

Lian-Li Has today launched their new UNI Fan SL-INF 140, a high-performance, near-silent 140mm PWM fan with stunning aesthetics.  

Outstanding Performance at a Whisper

The UNI FAN SL-INF 140 offers impressive performance with a maximum airflow of 72.7CFM and static pressure of 2.88mmH2O. Thanks to PWM control, the UNI FAN SL-INF 140 can offer a range of speeds from as low as 200 RPM to an amazing 1600 RPM. This powerful cooling performance is whisper quiet at 28dB(A).


The UNI FAN SL-INF 140 offers clutter-free, straightforward installation with Lian Li’s unique interlocking mechanisms in the frame of the fan. Up to four fans can be daisy-chained together and connected either to a controller or directly to the motherboard with a single cable. If more fans are required, two clusters of three fans can be linked together, totalling six fans via only two cables or the Lian Li Fan Controller can support up to 16 fans.

Stunning Aesthetics 

Aesthetically the UNI FAN SL-INF 140 offers a stunning appearance due to its three infinity mirrors and RGB lighting. The mirrors can be found on the fan hub and on the sides of the fan frame, with a unique geometric shape creating a 3D image that stretches through the fan frame. RGB adorns the fan with four LED strips surrounding the fan blades and RGB lighting circling the Lian Li logo.

Total Control With L-Connect 3 

Lian Li’s L-Connect 3 software offers full control over both performance and aesthetics. The software allows you to control fan speeds, monitor performance and can recognise the fan clusters installed as well as identifying the makeup of each cluster. The software includes modes to meet a variety of needs including, quiet, balanced, and high-speed operation as well as a zero RPM mode for when the system is idle.  

RGB can also be customised through the software and can even assign colours and effects to fans individually or to a specific cluster.  

Additionally, the performance of other components including CPU temperatures, memory utilisation, and storage drive capacity can also be monitored via L-Connect 3.
