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.

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

Fan stickers are not available seperatly.

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).

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.

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.

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.
