I figure I have the same issue (sorry, didn't read all 8 pages). I used to have CUE and Link and everything worked fine. Then CUE told me there was an update and suddenly I had iCUE instead. I then uninstalled Link (and rebooted, becuase I didn't see my AiO in iCUE at first).
Now I've set up my K70 RGB, M65 PRO RGB, H110i, RM750i and Lightning Node Pro with 5 LL Fans (2x 140, 3x 120) to static colors. And everything works great, except:
Until the driver is loaded (i.e. after Windows is started) and as soon as I shut down Windows, the fans (and only the fans) go into rainbow mode Sometimes, the fans go into static color mode once the driver is loaded. But more often than not, as soon as the driver is loaded, the fans go into "ultra rainbow" mode - pretty much what most people seem to see in this thread. Ending the Corsair Service process resolves this and they go into static color mode shortly afterwards.
Previously, the fans would be displaying the correct static color from when the PC powered up until it powered down.
Contrary to many/most/all of the posts I've read in this thread, I have no strips.
EDIT: this is iCUE 3.4.95
