cluster-

I realised that I haven't actually tried downgrading the LNP like you did. I'm going to have to try that, but it'll have to wait until next weekend for me though. I think I still have my LNP lying around somewhere. *scratches head* >> HD RGB Fans won't work via link and lighting node pro

Have you by any chance played The Division 2? I remember that they loaded custom lighting profiles when I started the game for the first time. Don't know if that's the cause, but it's the only other thing I can think of.

Sry, just updated my specs with the model. :)

I have the exact same issue. Same problem description. Same troubleshooting. The status for me right now is that only 2 out of my total 5 LL fans actually give away any light what so ever. Only 50 % of the first fan in the chain actually renders the set lighting effect. The other 50% of the first and the first 75% of the second fan is all disco lights. The last 25% of the second fan on to the rest of the fans are completely turned off.
