Question about Lian-Li O11Dynamic XL

can only tell you how to control it with aura sync.you have to connect the sata plug and the argb cable from the lianli hub to the header of the mainboard for addressed rgb.additionally you have to press the mod button on the case until you are in mainboard mode.then you can control the strip via aurasync in armoury crate.so i did it this way,that i set the colour red in the armoury crate software,then i pressed the mode button on the 011 until the colour appeared.then i could control the whole thing via the software.

I don't know if the front led is displayed separately. But you will certainly have to use the front button to select through the standard colours until you have the controllable setting. The best thing to do is to set the entire PC to an unthinkable colour in the software. Purple/pink and press the front button until the colour appears. Then you know you are on the right channel.
