Same issue for me TT RGB Sync controller and I have to reboot my PC 1-4 times touching nothing in-between and during one of those reboots it works.. I had a TT sync controller with 6 Riing plus fans that some of the fans stopped lighting properly. I got the Riing Trio fans and controller and and plugged some of my riing Plus fans over so i have the ports on the controller filled. I dont like how the software also flashes up at the start of Windows. The fans look great the software is very meh. Unless I can get something figured out i will just pull all the fans back out and go with corsair eco system as i already run icue for my keyboard and know it works.
