I recently bought a mb320l pc case and it comes with 2 argb fans included with a splitter and controller but the problem is the splitter has two cables one of them plugs into the controller but that’s isn’t the problem the fans led lights work fine it’s just the other cable ,it’s supposed to connect to the motherboard and make the fans spin and I think it’s a 3 pin cable I’m a noob at pc this is my first build soo yeah ,the problem is my mobo doesn’t come with the specific header for the cable and i don’t know what to do I need help ASAP I’m going insane
