Let me describe the situation,
Initially I bought the 3-pack LL120 RGB, and its working fine. Then I decided to buy another one to fill my case. The fan spins, but no LED lights up, then I searched the forum and found out that I need to change the number of fans in the Lighting Setup in my Node Pro. But nothing changed.
I tried to switch my new fan to first, second, and third port and is working fine. I'm also tried to switch the known working fans to the fourth, fifth, and sixth port (with the 6 fans option in the Node Pro) but none works.
Is it possible that my LED hub is faulty, or the included hub indeed intended only works with 3 fans altough 6 ports are available?
If it is faulty, I've contacted my seller to RMA'd it, and I have to return the whole 3-pack bundle, which is too much hassle for just one hub.
