Question RGB turns on but the fans don't spin

[SirRudolf]

When I boot my pc everything turns on except the case fans. The rgb on the fans turns on too but they don't spin. The fans are connected to a fan controller build in to the case (I have the sharkoon tg4). The fan controller gets its power from a data cable connected to my 620w psu. According to the manual I can connect the controller to my motherboard (an x470 aorus gaming pro) with a VDG cable or a 5v ADD Header. I found multiple vdg ports on my motherboard and when I connect it I can change the rgb lights with gigabytes rgb fusion. So everything seems alright except the fans don't spin. Hope you can help me!

Edit: the fans came pre-installed with the case.

Did you plug the connection from the rgb controller (case) into the RGB connection on the motherboard? Also re-seat the connection from the PSU to the RGB controller.

Reseting the sata cable didn't work. I have my controller plugged into the VDG header on my motherboard. That's what it said in the instructions from the case.
