It seems that the RGB controller that came with the case/fans has a 4-pin cable to connect to a motherboard's fan header. Since you have a Gigabyte Aorus Gaming 5 motherboard with RGB Fusion software, you may need to use the RGB headers on the motherboard. You should check the motherboard's manual to identify the specific headers to use, as there are different types such as 3-pin and 5-pin RGB headers. If the RGB Fusion software is compatible with the Riing fans, you may need to connect the RGB controller to the appropriate RGB header on the motherboard as per the manual's instructions in my location.
