Phanteks has a DRGB controller that might be what you need:

EDIT this wont give you precise control like Icue or Aura can, but it has a few hardware lighting options.
Phanteks makes a digital controller that should be all you need and can stick with the non lux halos.
Also getting this board and that is what my plan is so can't say for sure how it will work out. From what I have read it will all still work with Aura.
Edit:Added my experience with this.
