Regarding the issues with fan lights not turning on or color not changing:

1.Primary Cause: Insufficient power supply due to daisy-chained cables

Most motherboards only have one or two RGB headers. If your case is fully equipped with 10 or more fans daisy-chained together, it is highly likely that the power supply is insufficient.

Suggested Solutions:

1)Connect the fan’s 3-pin power cable to other available headers on the motherboard.

2)Use the fan individually (not daisy-chained) to see if it works properly.

3)Purchase a hub to supply power to the fans directly from the PSU.

2. Cause: The motherboard's lighting control software is not installed or not properly configured

Suggested Solutions: Each motherboard brand has its own RGB control software, please make sure the correct software is installed and the fan lighting is configured properly.

1)ASUS motherboard: Aura Sync

2)MSI motherboard: MSI Center

3)GIGABYTE motherboard: RGB Fusion

3. Cause: Hardware-related issue on individual fan components

Suggested Solutions:

1)Connect the fan’s 3-pin power cable to a different header on the motherboard.

2)If using a controller, make sure the lighting switch on the controller is turned on.

3)Test the non-functioning fan individually to determine if the issue is with the fan itself.

For the noise issue with the fan, please take a check:

1. Cause: Foreign objects such as cables or dust interfering with the fan blades. Suggested Solutions: Check if any cables, dust, or other debris are obstructing the fan blades.

2. Cause: The fan may create noise due to resonance with the PC case at high speeds. Suggested Solutions: Please test the fan outside the case to see if the noise persists.

3. Cause: Noise caused by deformed fan blades hitting the frame. Suggested Solutions: Check if any fan blades are bent or cracked, and inspect the inner frame for scratches.
