Controls +6 fans detected, but no response

[Jurgen-DOUCHY]

Added the reg key as recommended.
Control is not working and fans are not responding.
Always at 0rpm even if they are clearly spinning.
No change on the physical fans when I change the speed on the controllers.
Everything is showing, but nothing works basically.
