I just got a Carbide case it include 3 fans with two connection each.One 3 pin for the fan and one 4 pin for the LED control. The 4 pin connectors are a chained together and then to an adaptor that also has 4 pins. According to the included manual the 4 pin RGB is supposed to be connected to a 12v connector on the motherboard. I don’t have that connector on my motherboard. So how can I connect them?
