Hi,
I believe this is something you may want to try and look in their support forums.
But I'll give you 2 advices:
The card's software should have something independent to control it.
Example: ASUS Graphic Cards have either the GPU Tweak or the Armoury Crate to control RGB, look for it in the vendor's website. Same as AMD Wraith cooler, I could use the proprietary software or Armoury Crate.
Lastly, you can use a third party one like SignalRGB or OpenRGB to pick it up.
Good Luck
The Englishman
