Model TL FLEX 120 - Single Pack

  • 8-inch 400 x 400 LCD for custom visuals and monitoring
  • 60 Hz refresh rate keeps animations smooth on the display
  • Reverse-blade design directs airflow for specialised cooling layouts
  • ARGB lighting syncs via 5 V 3-pin motherboard header
  • USB 9-pin connection unlocks full L-Connect 3 display control

Single Fan with LCD Display

This 120 mm case fan includes a 1.8 inch LCD screen that runs at 400 x 400 resolution and 60 Hz refresh rate. It supports MP4, GIF, JPG and PNG files for custom visuals or monitoring. The reverse blade design and ARGB lighting are controlled via 5V 3-pin motherboard sync or wireless options. No controller is included in the single pack.

Control Depends on Connection Method

Full LCD functionality and video uploads require the USB 9-pin cable and L-Connect 3 software. Without the USB link, the screen cannot display custom media and lighting is limited to motherboard ARGB control. Fan speed can still run via PWM, but display personalisation is locked. Buyers who want plug-and-play visuals without extra cabling cannot use this fan as intended.

No Controller Included

The package contains only one fan and the Flex receiver; a separate controller must be sourced if the build lacks USB 9-pin headers or motherboard ARGB headers. Builders who need daisy-chained fan management or a dedicated hardware hub cannot achieve that with this single unit alone. Ensure the case has the required header before purchase.

Questions about this item

Should I buy the TL LCD Flex single pack or a multi-fan kit?

The single pack contains one 120 mm fan and no controller. Choose it if you already own a compatible receiver or plan to run only one fan. Multi-fan kits add extra fans and the required receiver in one box.

What does the 1.8-inch 400 x 400 display actually show inside a case?

The screen runs at 60 Hz and plays MP4, GIF, JPG or PNG files. In use it shows real-time temperatures, loads or custom artwork visible through the side panel.

Does the 5 V 3-pin ARGB header limit the fan speed or LCD features?

The ARGB header controls lighting only. Fan speed is still managed by PWM, while full LCD video upload and display customisation require the USB 9-pin connection to the Flex receiver and L-Connect 3.
