UNI FAN Wireless - LIAN LI is a Leading Provider of PC Cases

There are different things you can try: Make sure the fans have sufficient power. You can tell by the lighting on the fans, if they’re blinking white light constantly (when log-in to windows) that means power is insufficient. In this case, use the PWM to SATA adapter cable.

Re-plug the L-Wireless Controller while L-Connect 3 is open.

Go to Setting–General–Re-start Service and UI button, and wait for L-Connect 3 to re-open itself.

Some of my devices have a red icon in the L-Wireless Sync settings page.

Follow the steps:

The red icon indicates the device is previously bind by another L-Wireless controller, you can check to see if the shown controller ID is the same as your local ID.
Click the light bulb icon on that red icon device to make sure it’s the device you want to use (the device will show yellow light after light bulb icon is clicked).
If it’s the device you want to use, click refresh to unbind this device before rebinding.

How to check local ID?

In the L-Connect 3 interface, select “L-Wireless Sync Setup” on the left side. You can find the Local Controller ID at the top of the page.

Some of my devices change to white light after several hours.

Follow the steps:

This means that the device has been unbind due to 2.4G interference. Please re-bind the device.
Switch to a different 2.4G Channel in L-Connect 3.

If the fan is recognized as an unexpected model or appears as an “unknown device” after binding:

Please go to L-Connect 3’s Settings and select Restart UI & Service.

Interference

The lighting effect is showing a mix of different colors and flickering a lot.

Go to the L-Wireless Sync settings page to manually change the 2.4G channel. You can select any channel.

My Wi-Fi speed is suddenly slow when I’m using LIAN LI wireless products.

Go to the L-Wireless Sync settings page to manually change the 2.4G channel (You can select any channel.),and reconnect your Wi-Fi.

My other non-LIAN LI wireless devices malfunction when I’m using LIAN LI wireless devices.

Go to the L-Wireless Sync settings page to manually change the 2.4G channel (You can select any channel.),and reconnect your wireless devices.

LCD (Power Related)

If the fan LCD is stuck on blinking LIAN LI logo / are all blacked out / frequently restarts / disconnects from L-Connect 3 :

It may be due to insufficient power. Set the PWM ports the wireless fans are plugged into to PWM mode at full speed. (When fan # less than 3 )
If the issue persists or the fan number is more than 3, connect the fans to the 1 to 3 SATA cable. The 1 to 3 SATA cable came with the UNI FAN Wireless three-packs or the stand-alone L-Wireless Controller pack.
Or use the LIAN LI Universal USB & PWM Fan Hub or something similar for more stable power delivery.

LCD (USB Signal Related)

If one of your fan’s LCDs within a group or chain is blacked out / showing image ghosting:

If I click the screen option, the number of LCDs shown is incorrect, and one or two of my LCDs is missing. One or two of my LCD fans’ screens are not lit up, and the LCDs are not detected in Device Manager:

Hot-unplug the entire LCD chain.
Shuffle the order of the fans, and put the unlit LCD fans to the front of the chain.
Hot plug the entire LCD chain back.
If that didn’t help, try switching to a different USB port. If you’re using a USB hub, please also check if too many USB devices are connected.
- USB splitter cable without SATA for additional power: supports up to 6 LCD wireless fans.
- USB splitter cable with SATA for additional power: supports up to 9 LCD wireless fans.

LCD (Windows System-Related)

If I click the screen option, the number of LCDs shown is incorrect, and one or two of my LCDs is missing. All the LCD fans show the LIAN LI logo and the correct number of LCDs are detected in Device Manager, but some LCDs are not detected in L-Connect 3.

-Follow the Steps:

Click restart LCD, wait for the LCD restart to finish, then try to upload content to the LCD again.
Go to Setting–General–Re-start Service and UI button, and wait for L-Connect 3 to re-open itself.
If all of the above doesn’t work, download this USB path cleaning tool (check here).
If all of the above doesn’t work, please re-install Windows, and after the reinstallation, install L-Connect first before any other drivers.

Occasionally, when I reboot the PC, some screen will not have the memory of my previous setting?

-Follow the Steps:

Make sure that each USB port (internal 2.0 or back io 3.0) on MB only has 6 LCD max if the used usb hub does not have individual power. If the usb hub has individual power, make sure each USB port on MB only has 9 LCD max.
If step 1 does not improve, then wait for our next version to refine.

How many UNI FAN SL Wireless LCDs can I connect?

When plugging directly to motherboard USB 2.0 9-pin: 3
When plugging to motherboard USB 2.0 9-pin with a USB splitter: 6
When plugging to motherboard USB 2.0 9-pin with a USB splitter that has SATA power: 12
*One computer supports at most 20 UNI FAN SL Wireless LCDs.

Fan Speed Related

The motherboard BIOS cannot read UNI FAN SL Wireless Series’ fan speed, even if I correctly enable MB RPM SYNC, and make sure that the 4 PIN PWM cable between controller and MB 4 PIN Header is plugged properly.

This issue will be fixed later on through firmware update. As of now, please read the fan speed through L-Connect 3.

Lighting Related

Why can't Strimer Wireless and UNI FAN SL Wireless sync their lighting effects when Quick Sync is set to breathing mode?

If you wish to sync the lighting effects between Strimer Wireless and UNI FAN SL Wireless, please use Quick Sync lighting effects labeled with W*.

When I select MB lighting Sync, there is no change to the LED, and cannot be controlled via motherboard software.

L-Wireless Sync will not support 5v 3p style-sync method, but we are working on 3rd party synchronization i.e. SignalRGB, and plan to update this feature soon.

Others

I can only use one L-Wireless controller per system?

Currently, there’s no support for two L-Wireless controllers per system, but one L-Wireless controller can support up to 10 channels already.

If I want to connect the fan’s power only to the motherboard's PWM port but the power is insufficient.

Please enter the BIOS and set the corresponding fan header to PWM mode, as only PWM mode can stably output 12V power.
