Riyujin 2 no fan control

[selfa]

Hello,

I can't control the fan speed of my Riyujin 2, the value stays at 0 in Armory Crate even though they are spinning fine.

The fans are connected to the small box supplied with which is connected to the screen which itself is connected to the motherboard via usb.

I don't understand why I can't control them, any idea?

Thanks in advance

Check if the fan1 slot in the controller box is connected to one fan at least one fan don’t leave it empty and check in armory crate
