I have a set of the very same fans and a gigabyte X299 gaming 7 and I can confirm that it doesn’t work or not yet anyway.
when you open fusion you can’t access anything to do with the Riing fans (its greyed out). I’ve just come on here searching to see if there’s anybody that’s got it working but can’t find a shred of evidence to support it.
Maybe there’s a update from Thermaltake or Gigabyte on its way soon that will make it all kick in but as for now it’s a thumbs down.
