Ok, after some searching I have come to realize that its a bloody mess to find out.
The info on Asus site is only available as you watch one of the movies, and thus you get In-Win. After some additional searching I found that many, if not all, many of the CoolerMaster RGB fans are Aura compatible, with the Aura logo on the fans description on CM's site. After that we do of course have Lian-Li as well, but looking on the site I see the Aura logo only on the Bora-Lite series.
There is of course another aspect in this, if you are cunning enough to determine from the technical specifications that the Fan should work with Aura, regardless of Aura logo on their site, then feel free, buy it. I am not that cunning, yet.
I find the lack of correct information on behalf of Asus disturbing. After all, the fans must have been approved for the Aura logo rite?
