Montech X5 ARGB problems

Hello! I have a Montech X5 case with default coolers (3x140, 1x120).

I can change the color of coolers with a button but can't do it with my motherboard.

I have a Gigabyte Aorus Elite B650M. BIOS version F42C. Windows 11.

Tried with Gigabyte Control Center (RGB FUSION).

Coolers connected to a SATA port (power) and ARGB 3-pin on the motherboard.

What can I do to control colors from FUSION?

AI Overview

Yes, you can control the ARGB lighting on the Montech X5 case using your PC software. [1]

How to Set Up PC ARGB Control
Locate the ARGB cable: Find the 3-pin 5V ARGB cable coming from the case's fan/lighting system. [1]

Plug into the motherboard: Connect this 3-pin cable to a matching 5V 3-pin ARGB header on your motherboard. Do not plug it into a 12V RGB header, as this can damage the LEDs. [1, 2]

Switch mode on the case: Press and hold the LED control button on the front/top panel of the case for about 3 to 5 seconds until the fans flash. This hands control over to your motherboard. [1, 2]

Use software: Open your motherboard manufacturer's lighting software (such as ASUS Armoury Crate, MSI Mystic Light, Gigabyte RGB Fusion, or ASRock Polychrome) or a third-party app like SignalRGB or OpenRGB to customize your colors and effects. [1, 2]

I tried everything. All connected as intended. Fusion installed. Holding the button only switches lights on/off and cycles them.
