Hi, from the led hub (has two slots) you can use one to control your Corsair fans, maximum 6 (is a separate RGB hub for 6 fan connections) and the other led hub you can use for LED strips from Corsair. If you want to control more than 6 fans, leave out the LED strips and connect a 2 RGB hub there, then you can control the RGB of 12 fans through Corsair's ICue software. Greetings
