Glad you got yours working in the end. I replaced all my fans and commander pro still got same problem so this still leaves me to believe it's the software, theres no way all the stuff I replaced is faulty also.

I contacted Corsair support and they said they can send out a new commander pro although this isn't really a solution to the software acting up. I told them and they pretty much just said to try uninstall delete files and use CCleaner, doesn't look like we will be getting a fix truly unfortunate after spending a lot on the fans to not work as intended. There's no pattern to it some days it will work fine and other days it goes haywire rainbow vomit or no colour at all.

I have the same issue the fans spin but all the colours are incorrect definately a software issue but corsair don't seem to want to fix the issue, had this problem for over 8 months recently bought new LL120 fans and commander pro still same issues so surely it has to be the dodgy firmware. You can try all the simple troubleshooting stuff they tell you to do but good luck on that working.

I also did this to rule out faulty fans forgot to mention. It does seem it's tied to iCue since all all this stuff is brand new, it was doing it before on the old fans and commander pro, seems to be the firmware but I cannot revert it as I can't find any older downloads for it.

I have been having issues for the best part of 8 months with these LL120 fans now when they work they are great but they seem very temparmental or the iCue software, my fans will randomly show wrong colours or go black for a few mins for no reason at all flickering etc. I have replaced all the fans and the commander pro. I have tried 1 fan at a time to eliminate a faulty fan but none of this seemed to help, now I am starting to think this is just a bad firmware which I cannot roll back or anything. I have been trying to read into this issue for months now seeing similar posts and it's always the same fans LL120 some people report the LL140 ones do the same, so my question is are these fans just bad or is it the software that's just causing these to act up. It's just very annoying this issue is still ongoing for so long and I just want to know if corsair are aware of this issue because it seems to be a lot of people having problems with this but no actual word from corsair about it besides the basic troubleshooting. iCue version - 3.18.77 Commander pro firmware version - v.0.9.212 K95 keyboard firmware version - v.3.21.7168 Also to note I have the hydro x custom watercooling res/loop when the lighting glitches on the fans for a split second the lighting turns off on the hydro x stuff, so this leads me to believe it's a issue with iCue not the hardware. Any help is much appreciated maybe I just need to roll back the firmware somehow but I can't find any downloads for it.
