LL140 LEDs simple wont turn on

[cripticcore]

so i’ve looked through all the forums posts and people have similar issues but all of them have something to do with the iCUE software, mine however dont turn on at all, they worked at first when i put together my case but when i trouble shooter some other case fans when i powered the pc on the LL140 lights just don’t turn on(the other case fans aren’t connected to the corsair ones at all)

On very first power on, the fans will typically go rainbow. However, once you reach the Windows environment with CUE installed, you then need to do your lighting set up. You must tell the program what fan type is connected and how many there are so it can generate the proper number of LEDs. Until you do, it remains blank (off) with no UI elements to interact with.
