I have an Asus z390-a motherboard with 3 packs of the Ring Trio 12 fans. 5 fans into controller 1, 4 into controller 2, controller 1 switch flipped up. Controller 1 is connected to molex and Mobo 2.0 USB connector. Controller 2 is connected to molex and bridged to controller 1. My first 5 fans light up, can be controlled, show up in ttrgb plus, basically works perfectly. The problem is that fan controller 2 does not. I've switched to a 3rd controller to eliminate that possibly being an issue (3 boxes of ring trio fans, so had an extra controller to troubleshoot with), my last 4 fans, that are hooked into the 2nd fan controller spin, but don't light up. That was not an issue for about 2 months, then all of a sudden, poof, doesn't light up but the fans still spin. The weird thing is, is that sometimes over the course of long gaming sessions, fans 6-9 will light up Rgb, but still be uncontrollable through ttrgb plus. The 2nd controller does not appear either. I fiddled with it, took the fan connectors out of the controller, and I saw controller 2 become accessable in ttrgb until I tried plugging a fan connector back into it. Trying to find out what's going on, it's frustrating me endlessly, and all troubleshooting thus far has been with fail. Any help would be appreciated, I am so confused as to why it is operating like this, thanks so much!
