Be sure to get the right led count on the Devices menu in Armoury Crate is correct, the easiest way to do is set a static color in aura, then go to evices (Third Menu Item on Armoury Crate) and start with a number like 10, accept it and see if all lights on the led strip or fan are ON, increase the number until you can see all the leds on the accesories are ON. Then check on aura if everything is working as you want.
Remember that each argb connector is independent on led count
I get a screenshot of the Armoury Crate Devices Menu (In Spanish but it is almost the same)
