2. Restart L-Connect 3 service
3. If swapping doesn’t fix the issue, then contact us via “form” with this result to replace the entire fan group.

4. The fan is only showing partial lighting, and also causing the fan connect after to lose lighting

4.1 Check if power is supplied from included SATA-PWM splitter or PWM 12V Hub (such as Edge Hub or Edge Gold’s Hub).

4.2 Swap the receiver between different fan groups to check if it’s the receiver causing the issue.

4.3 If the issue persists, then contact us via “form” with this result to replace that fan.

5. Devices Missing from Wireless Sync Setup List (Disappeared from UI)

5.1 Confirm L-Connect version is on the latest version.

5.2 Check if Wireless fan’s power is supplied from included SATA-PWM splitter or PWM 12V Hub (such as Edge Hub or Edge Gold’s Hub).

5.3 Close the L-Connect 3 service, wait 10 sec, unplug the wireless dongle, and plug it into the rear I/O USB-A (rear USB port recommended). Restart the service afterward.

11. If your UNI FAN SL-INF Wireless shows signs of: Higher fan speed than expected within a fan group / Unstable or fluctuating fan RPM / Slow response to fan speed changes in L-Connect 3

11.1 Change the wireless channel in L-Connect 3 to resolve the issue.

12. I’m using LIAN LI Wireless devices, and every time I start the system, L-Connect 3 takes a long time to open.

12.1 By default, the software delays the Service startup by 3 seconds after boot. You can change this to 0 seconds in the Settings menu.

12.2 Additionally, the wireless transmitter initialization has an extra 5-second delay, which can make the startup feel even longer.

12.3 We recommend enabling Fast Startup in Windows and setting the shutdown behavior to Sleep instead of full power-off for a faster startup experience.

13. I’m using the LIAN LI wireless device and have confirmed that all wireless dongles are properly connected. I’ve also updated to the latest software, but I still don’t see the wireless sync setup option.

13.1 Go to windows service
