Hello,
I have ran into a issue with my build. I have 6 Corsair HD120's connected to the Commander Pro and the RGB hub connected to the commander pro but only 1 fan has the rgb functioning correctly and another just has a single green led lit up. I have disconnected them and plugged each one up individually to the #1 slot on the RGB hub and they work as designed so i ordered and replaced the RGB hub believing it was bad and the same issue still exists. I have updated the firmware in the commander pro and the iCue software and still no change. I have the channels selected in the Icue software for HD fans and selected 6 for that LED channel. Any suggestions or ideas would be greatly appreciated.
