Does L-Connect 3 support STRIMER PLUS?

To recognize STRIMER PLUS in L-Connect 3 requires a new controller, for more information please view STRIMER PLUS V2.

Can't succesfully sync RGB to motherboard, I have installed a third party software, ex. SignalRGB...

Third party software is conflict to L-Connect 3, which cause uncontrollable issue. Please remove third party software to control with L-Connect 3.

Just updated to L-Connect 3 from L-Connect 2 or L-Connect 1, L-Connect 3 can't control anything.

Please folow guide to complete remove the old version and install the new version.

L-Connect 3 is experiencing issues.

Please install Microsoft Visual C++ Redistributable to enhance compatibility for L-Connect 3 with Windows.

L-Connect 3 is using heavy CPU load.

We suggest to keep sensor display at a maximum of 3 for UNI FAN TL LCD to reduce CPU usage.

ACCESSORIES

UNI FAN SL/AL V1

Which fan header shall I connect to?

  • Recommend you connect the controller’s PWM cable to the system/chassis fan header (not the CPU nor pump fan header).
  • You could wire the fan’s PWM cable to the CPU header directly if you use UNI FANs for your AIO.

How to check if UNI FAN is connected to PC or not?

- Check your [Computer Management] → [Device Manager]
- If your MB detected UNI FAN, it would show [LIAN LI] under [Universal Serial Bus Device]
- If there are error under [Universal Serial Bus Controllers], please contact your MB company for help.
-Check if all 3 cables of the controller are correctly connected to the MB. Switch another USB2.0 header if necessary.

I don't have enough RGB port and I don’t want my fans sync to MB, do I need to connect the 5V ARGB cable?

If you are not connecting 5V ARGB cable from the controller, you can only control the RGB from L-Connect.

Selected PWM mode on L-Connect, but fan speed doesn't sync to motherboard.

Please enter your MB BIOS and select the connected fan header to PWM mode (not DC mode nor Auto mode).
View example.

The new UNI FAN SL comes with a sticker, can I get an extra one or buy one?

Fan stickers are not available seperatly.

The led color of UNI FAN SL and AL suddenly change to a different color after using a while.

UNI FAN Connecttion Pad
UNI FAN Connecttion Pad
There might be some dirt on the pin to pad connection. Please disconnect the fan and clean the pin to pad connection with alcohol or eraser.

UNI FAN SL/AL V2

I have both 120mm and 140mm, the 140mm spins slower.

Set the fan size at the Fan/ Pump profile to the corresponding fan size to obtain accurate fan speed.

UNI FAN SL INFINITY

There are two SATA cable, which one should we plug?

Recommend to plug both on different SATA cable, as close to the PSU as possible, do not connect other device to the same SATA cable.

How to set fans to PWM mode?

Go to Fan / Pump RPM page and turn on MB mother sync

Which controller shall I connect?

All UNI FAN SL-INF 120 / 140 and 120/ 140 reverse blade supports the same SL-Infinity controller.

UNI FAN TL Series

Unable to control the TL LCD screen suddenly.

Start the L-Connect 3 background service by following the provided steps.

The L-Connect 3 doesn't detect TL series fans.

  1. Ensure that you are using version v2.X.X.
  2. Make sure to connect the USB 2.0 9-PIN of TL controller directly to the motherboard, do not use a splitter.

UNI FAN TL LCD screen is laggy and sometime flashes.

Ensure that the TL LCD fans are not connected to the 1st port.

Connected more than 7 TL fans to a port, the fan speed isn't stablize and the white color LED turns yellow.

Make sure to connect the power adapter to SATA to ensure stable operation.

One of LCD screen is not displaying after FW update.

  1. Ensure that it is connected to port 2/3/4 on the controller.
  2. If it doesn't work, remove the power cable and connect it directly to the fan that is not displaying. Start to do FW update for single fan again.

TL LCD screen is flickering

If your TL LCD screen is flickering, we recommend that you download the latest driver from Nvidia or AMD's chip manufacturer.

TL LCD and the controller lose the USB connection time to time.

This happend to some AMD motherboard, please folow below steps to fix.
  1. Remove all LIAN LI controller USB cable manually
  2. Update motherboard BIOS to the latest version
  3. Download AMD latest chipset driver. Quick Link B550 , X570
  4. Reboot the PC and turn off again and connect all the USB cable and restart

The fan signal is abnormal, causing the LCD screen to loose display occationally or the LED strips not fully illuminated.

Please loosen the screws of the fan for the signal to pass through successfully.

TL LCD Screen flickers at sensor display.

Please update your GPU's latest driver from their official website. (ex. Nvidia/ AMD)

Strimer Plus

How to sync Strimer plus 24 pin ARGB to my motherboard?

Push and hold M1 button for 3 seconds.

Strimer Plus V2

How many extention cables can be connected to the controller?

One controller only supports 1 motherboard cable (24-PIN) + 1 GPU cable (8-PIN or 3×8-PIN)

Strimer Plus V2 8-PIN and 3×8-PIN only supports a 5V ARGB header to motherboard, but the motherboard doesn't have enough 5V ARGB header.

Please purchace a exclusive controller box (included in 24-PIN as well), if there is no need to sync lighting effects to motherboard, don't need to connect the 5V ARGB header to the motherboard.

Galahad II Trinity

I have a Galahad II Trinity 360 AIO, the last fan doesn't have lighting effect.

Please download L-Connect 3 and set the fan number at GA II Trinity (R) > Extend ARGB header left bottom section.

Galahad II LCD

First time installing GA II LCD and experiencing black screen on the pump.

1. Connect the USB type C header to the pump firmly. Ensure it clicks into place without any gap.

2. Connect the USB type C cable directly to the motherboard's 9-pin USB header.

The pump noise is audible.

The GA II LCD AIO utilizes Asetek's 8th Gen pump, originally capped at a maximum speed of 2600 RPM. To address the growing demand for CPU heat dissipation, we have unlocked the pump's maximum speed to 3600 RPM.

We suggest using L-connect 3 build-in pump/fan profile function to set PWM curve, finding the optimal balance between noise and performance. The pump motor operates efficiently at 2200 to 2500 RPM for regular use, maintaining a friendly noise level.

Screen recording is not functionable.

Please completely remove the old version of L-Connect 3, refer steps here.

Unable to control the GA II LCD screen suddenly.

Please start L-Connect 3 background service, follow steps.

Failed firmware update resulting in a black screen

Please manually update the firmware by referring to the guide.

At every system reboot, the GA II LCD screen stops at the LIAN LI logo display, and the screen can't be controlled. I have confirmed that the USB type C is firmly plugged in, and the 9-PIN is directly connected to the motherboard. To resolve the issue, I need to restart the PC.

Here are the steps to update GA II LCD firmware to permanently fix the issue. Please refrain from updating the firmware unless you are experiencing this specific issue.

No, each controller has different chip set that will generate different led color and fan speed. Would not recommend to use the same controller.
