I bought the fans the other day and they came with some kind of lighting node. But now you can connect them directly to the mainboard. And you don't have to connect the lighting node again. A Sata cable is also needed and you can then connect the Rgb cables of the fans there. However, there are no extra fan power connections.

Nein, es wird nur ein Lightning Node mitgeliefert. Ich denke es handelt sich um diesen hier:

Corsair RGB Fan LED Hub

Yes, it's included, but we couldn't connect it to the other fans. Now they only light up in the rainbow colour.
