I have been having the same issue with my LL120 fans. I have 9 LL120 fans and 1 LL140 fan. Doesn't matter what lighting profile I put on the flickering is static. Restarting the computer sometimes fixes it but most of the time the flickering is still present. I ended up reverting back to the normal corsair utility software and the corsair link software. Since reverting back to the older software I haven't had the flickering issues at all. This sucks because I also miss out on a lot of features that the icue software provides including setting all my lighting in one place instead of having to set some lighting profiles with the link software and the rest inside the corsair utility. Corsair you need to fix this fast. Everyone here has spent a ton of money on these products only to be aggravated with the annoying issues.
