Lian Li TL Flex fan wiring and setup guide

Summary

The Provoked Prawn provides a step-by-step guide to installing and configuring Lian Li TL Flex fans, including LCD and LED models. The tutorial covers fan orientation, wiring, L-Connect settings, RGB lighting, and fan-speed control.

Fan Types and Placement

• TL Flex fans are available with standard or reverse blades, in LCD and LED versions.
• Reverse-blade fans are intended for intake positions where the visible side should face into the case, such as side or bottom intakes. Standard fans can be used as exhausts at the top or rear.
• Standard fans can also be flipped for intake, though this may expose the less attractive rear of the fan.
• Remove the screw-hole covers before mounting. For radiator installations, use the radiator’s longer screws.

Wiring and Power

• Connect fans side by side, aligning their contacts so power, data, and lighting can pass between them.
• Each fan group uses a receiver at its end. The guide recommends connecting no more than three LCD fans per receiver; LED fans can be added beyond that limit.
• Connect the receiver’s four-pin fan cable to a motherboard system or case fan header. The guide recommends powering the other connector from the power supply via SATA to ensure adequate power. For radiator fans, it recommends using a CPU fan header.
• Connect LCD fans to a motherboard USB header to enable advanced screen controls. A Lian Li USB hub can consolidate multiple USB connections, though using one for fan groups reduces independent motherboard fan-speed control.
• The included 5V ARGB cable provides an alternative for controlling lighting through motherboard software. An ARGB hub can expand the number of available connections and requires SATA power.

L-Connect Configuration

• Download and launch L-Connect, then use its wireless-sync settings to identify and bind each fan group.
• Test the lighting flow, then adjust the sequence for each group so effects travel in the intended direction. The software also lets you set fan orientation so screens display correctly in landscape or portrait.
• LCD groups can be linked for coordinated screen themes and transitions. USB connectivity provides more screen customization and startup options than a wireless connection alone.
• If screens or features do not work as expected, the guide recommends checking for an LCD receiver firmware update. After updating, you can select startup-screen options. Before Windows loads, the screens may show only limited information.
• Fan profiles include quiet, standard, high, full-speed, and custom options, as well as a start/stop setting. Groups can be assigned temperature sources—for example, coolant temperature for radiator fans and GPU temperature for bottom fans.

Tutorial Highlights

1. Choose standard or reverse-blade fans based on their intake or exhaust placement and which side should be visible.
2. Join fans into groups, attach the receiver, and connect fan power, USB, and/or ARGB as appropriate.
3. Install L-Connect and configure group identification, lighting direction, screen orientation, LCD content, and fan profiles.
4. Match fan-control temperature sources to the components the fans are intended to cool.
