I don't understand this part, but it doesn't match any common fan connector. Your motherboard features several fan headers, and it's likely compatible with RGB fans too. Standard fan headers usually have 2 to 4 pins. If your case's fans use different connectors, they might be combining the usual 2-4 wires for a standard header with RGB wiring, creating a unique connector they expect to work with a controller you've installed.
The fan connected to my old motherboard functioned properly. The wire you're displaying links to the fan, while the other connector is meant for another purpose but I'm not sure.
