Because the iCUE Lighting Node CORE lighting controller is included in the two-pack. (Price approx. 14.-) This allows the fans to be controlled via Corsair's ICUE software and the lighting to be changed.
Hello Avi
I use 2 Corsair Comander Pro modules and the ICUE software for speed and light control of my 2 QL140 fans and 6 QL120 fans, this works perfectly. I have connected the Comander Pro in "series". So one Comander Pro is plugged directly into the mainboard and the other Comander Pro into the first Comander Pro.
