I can also confirm i had it working on my Asus Crosshair VIII formula and it does allow controll of the leds, just not the rgb headers (dont know if only A-RGb or 12v RGB as i didn't have 12v hooked up, just Argb and it didn't listen to it :P )
on the other hand there was a 3 way error causing HW-info not to work, if i shut down icue, HWinfo would work, if i shut down HWinfo icue would work HOWEVER, when i removed the motherboard plugin from the icue files both would work as normal. considering i use the HWinfo plugin to show information on my streamdeck its highly annoying for it not to work.
