Three-Pack LCD Fan Kit

The Lian Li UNI FAN SL-INF LCD Flex arrives as a three-pack of 120 mm reverse-blade case fans finished in black. Each unit integrates a 1.8-inch LCD panel that can show real-time hardware data or custom media. The bundle targets builders who want synchronised cooling and per-fan visual customisation without mixing separate controller hardware.

Thermals Noise Power

Reverse-blade geometry pulls air through the heatsink or radiator with a focused flow path while the PWM curve adjusts speed to load. At typical desktop loads the fans settle into a low-RPM range that keeps audible noise subdued inside a closed chassis. Power draw per fan stays within standard 12 V PWM limits so the motherboard header or supplied controller handles the trio without extra cabling.

1.8-Inch 400 x 400 60 Hz Display

The decisive spec is the 1.8-inch LCD running at 400 x 400 pixels and 60 Hz, driven through the USB-linked receiver and L-Connect 3 software. This resolution and refresh rate determine whether animated graphics, photos or sensor overlays render smoothly on each fan face. Buyers who do not need per-fan video playback or detailed widget layouts will find the display capability exceeds their actual use case.

Questions about this item

How do I install the 120 mm fans and controller, and what step is often missed?

Mount the three 120 mm fans in the case, connect them to the included controller, then plug the controller into a USB 9-pin header and a PWM header; the step often missed is connecting the USB cable to unlock the 1.8-inch LCD display and full L-Connect 3 control.

What maintenance will the 1.8-inch LCD fans need over time?

Dust the fan blades and radiator fins every few months with compressed air or a soft brush; the 60 Hz LCD panel itself needs no user servicing, and the reverse-blade bearings are sealed for the product life.

What limit appears first when the three fans run at full speed for long periods?

The 120 mm reverse-blade design moves less static pressure than standard blades, so airflow restriction from dense radiators or filters becomes the limiting factor before motor or thermal limits are reached.
