Corsiar LL120 fans not lighting up or are partially lit.

[Kenji OV]

I've  had my  PC for over  a year and had no problems with the rgb  of my fans up until  recently. I have six ll120s connected to a lighting node and five of them don't  light up and the one that does light up only has the inner ring of LEDs working. I've tried uninstalling and reinstalling iCUE  but it doesn't work. But the header of  my  corsair AIO  works just fine.

The RGB for fans on most controllers is serial. From your description it appears you have an issue with fan #1 and that knocks out everything down the line. Try temporarily swapping your #1 and #6 fans on the RGB lighting hub or Lighting Node Core (whichever you are using). If the theory is correct, the other fans will come back on and the fan you moved to #6 will be partially lit. If true, you need a replacement LL.
