I am using the Corsair RBG ecosystem, including 6 LL fans, 4 strips, Corsair hub and commander pro.
So, after running into the issues with iCue 3.19 causing significant system performance issues, I uninstalled 3.19 immediately. This of course resolved the performance issues. At this time, all of my LL fans were working on the default rainbow pattern.
I went out of town for a day or so. Come back and fire up my rig, and only 1 of the fans is emitting any color. One of the other fans is emitting some color, but you can tell it isn't right. The other fans are spinning, but no color. I installed iCue 3.18, and forced an update of the commander pro firmware and that didn't make any difference.
Thoughts on what this might be? Anyone experienced this? I am nervous that either the hub and/or the commander pro is hosed.
