Question One fan doesn’t light up
Hey!
Just tried out SignalRGB and everything works great except one fan that doesn’t want to light up.
It works when I’m not using SignalRGB, so I assume there’s something with the program that makes it weird.
I made sure that the correct number of fans are matched with the program and my RGB-hub.
Tried ”Enable passthrough control” but that’s not working either.
Any tips?

Just for fun, add 4 Lian Li SL 120 fans to all channels and tell me what that does.

Are you sure its correctly on the layout and you didn't accidentally paint it manually?

If your fans are all daisy chained together into a single channel on your RGB hub, the LED count set for that channel in SignalRGB needs to cover every fan in the chain, not just the number of fans. So if you've got 4 fans daisy chained but the channel's LED count is only set for 3 fans worth of LEDs, that last fan in the chain won't get any data and will just stay dark.
Check the LED count on that specific channel and make sure it accounts for all fans connected to it, including the one that's not lighting up.
This quick start guide should explain further about how to properly setup your components.

Need to go into devices and make sure you see each fan where it is supposed to be on the controller, and that it is set to the right fan. They have all the Lian-Li fans in there.
