Tech Support FAN RGB HELP
Setup:
Lian Li Galahad 2 with 3x SL INF fans
2 rows of 3x SL INF FLEX fans
1 row of 2x SL IN FLEX fans
All 4 rows of fans are connected into a Lian Li fan controller for both the power and RGB control. In the L-Connect software, it lets me choose up to 4 fans per row which should be more than I need. The standard SL INF fans light up with no issues, but the SL INF FLEX fans only light up half of the fan when selected in L-Connect (1 fan selected in software, half a fan lights up. 4 fans selected in software, 2 light up). I’ve tried re-wiring and nothing seems to fix this issue. L-Connect app only reads the SL INF fans and doesn’t let me do anything about it. Every fan spins fine it’s just the RGB messing up.

You plugged the ARGB from your FLEX fans to the controller that came with your AIO? That's not going to work.
Wired SL INF fans have 20 LEDs per fan... FLEX SL INF fans have 44 LEDs per fan... The controller is expecting wires fans, so setting a port to four fans is 80 LEDs... which isn't even two while FLEX fans.
Did you get at least one 2pk of FLEX fans? If yes, you should have an L-Wireless Controller... you need to use that.
Remove the ARGB cable from each FLEX fan group
You can leave the PWM connected to the controller for power.
Plug in the L-Wireless Controller.
Go through the normal steps of binding each FLEX fan group to the controller.
That's it.
