Power Related Issues
My UNI FAN SL-INF Wireless' RGB blinks and the fan behaves erratically. I’ve connected both the 4-pin and 2-pin to the motherboard.

Some motherboards have low over-current protection (OCP) thresholds. High-brightness RGB and high fan RPM may trigger OCP.

  • Use an alternate header, ideally an upper position one on the motherboard.
  • Move the 2-pin cable to a SATA power source.
  • Avoid connecting multiple channels to headers in the same power zone on the motherboard.
Fan RPM Issues
The fan sometimes ramps to 100% even when idle.
Wireless interference from multiple controllers may block RPM signals. Also, if the receiver is powered via SATA or an external source, it can’t switch to motherboard RPM control.
  1. Connect the 4-pin cable to a motherboard PWM header and the 2-pin to external power.
  2. Alternatively, plug both the 4-pin and 2-pin into the same motherboard PWM header if supported.
RGB Setting Memory Issues
Occasionally, a channel forgets its RGB setting after a reboot.
If both the 4-pin and 2-pin cables for that channel are connected to the motherboard, try moving the 2-pin to SATA power for more stable voltage.
Motherboard RPM Direct Control
How can I use BIOS or motherboard software to control fan speed?
Ensure the 4-pin cable from the receiver module is connected to a motherboard PWM header. Then, open L-Connect 3 → Fan/Pump Profile → enable MB RPM Sync.
Unknown Device Detection
After rebooting, one channel shows up as "Unknown Device."
Go to L-Connect 3 → Settings → General → click Restart Service and UI. If the issue persists, contact RMA support to request a replacement receiver module.
