Not sure if I'm posting this in the right place, but I've completed my PC upgrades. (All products are from Corsair.) I installed 4 LL120 RGB fans with Lighting Node Pro and an RM750X PSU with excellent results. I also bought a separate Node Pro RGB because it was super cheap. It comes with 4 RGB strips for your PC case and also comes with the lighting node hub. There are two slots on them, and since I plugged the 4 fans into a fan hub which leads to the Node Pro, I had one other slot to plug in the RGB strip chain and I ended up not needed the second Node Pro hub. The fans work great and exactly as they should, but the lighting strip doesn't even turn on. As far as I can tell, it has all been installed correctly, and since the fans use the same Node Pro and work fine, I don't know what is wrong. Any help is appreciated, thanks!
