Lian Li has launched the Uni Fan SL Infinity 140, a 140-mm addition to its existing Uni Fan SL Infinity fan series that counts an infinity mirror at the front and sides, as well as thin, angular RGB strips at the front and rear, as some of its chief highlights. The new fans are available now in black or white as a single pack for $29.99 at retailers that include Newegg, according to a press release from the company.

UNI FAN SL-INFINITY 140 Features

  • Features same infinity mirror and lighting effect as SL INFINITY 120
  • Removable interlocking key and multi-directional cluster power cable for improved radiator clearance
  • Up to 72.7 CFM airflow, 2.88mm H2O air pressure, and 28 dBA noise level
  • Fan speed of 0, 200 to 1600 RPM with full support of fan curve adjustment from L-Connect 3
  • Fully compatible with UNI FAN SL INFINITY 120’s controller hub for using different combinations of 120mm or 140mm fan clusters

From a Lian Li press release:

The SL INFINITY 140 delivers much improved airflow with a maximum of 72.7 CFM, 2.88mm H2O of air pressure; noise levels reaching only 28 dBA while running at 1600 RPM, or completely inaudible at 0 RPM with the Start/Stop function in L-Connect 3. The SL INFINITY 140 is fully compatible with the SL INFINITY controller hub, giving users the flexibility of using different combinations of daisy chained clusters of 120mm or 140mm fans in their build. Similar to the 120, it comes equipped with the improved connecting mechanism of removable interlocking keys and a multidirectional power module cable.

Mesmerizing. Illusory. Limitless Lighting

The SL INFINITY 140 features 40 LEDs which are dispersed perfectly to provide continuous lighting at the fan blades and around the LIAN LI medallion in the back. The front fan axis offers a glimpse into the first infinity mirror ring which has been carefully designed to create a deep, hypnotic infinity effect with 0.5mm between each layer of light. The second infinity mirror is surrounded by an aluminum trim located on both sides of the frame. With the L-Connect 3, users can decide between preset light effects or combine center and side light strips for a customized look.

Better Airflow. Better Air Pressure.

The SL INFINITY 140 features improved airflow (72.7 CFM), a higher air pressure (2.88 mmH2O), and selectable fan speeds of 0, 200 ~ 1600RPM, all while at lower noise levels (28 dBA). Perfect for heat dissipation or general air intake. The SL INFINITY 140 also supports 0 RPM for the ultimate silent build. This feature is supported by L-Connect’s redesigned fan curve interface via the Start/Stop mode which allows RPM to be set to 0 when the CPU or GPU is running below 50°C.

More Flexibilty for the SL INFINITY Series

The SL INFINITY 140 is fully compatible with the SL INFINITY controller hub, giving users the flexibility of using different clusters of SL INFINITY 120mm or SL INFINITY 140mm fans in their build. The SL INFINITY 140 includes removable interlocking keys on the side of the fan for better clearance with radiator fittings. The power module is centered on the fan frame and has been revised to allow the cable to be flipped 180 degrees, so as to always be oriented towards the rear of the case. The SL INFINITY 140 single pack comes with a power module cable that splits into a standard PWM and 5V-ARGB cable to allow direct connectivity to the motherboard.
