I have 3 corsair sp 1 ml which are connected to commander pro. The ml has rgb but 3 sp dont have. They are all spinning. the problem with icue software or hardware?
You can not mix fan types on the same RGB Fan Hub. If you have 1 ML and 3 SP then you need to RGB Fan Hub's to control the RGB on all 4 fans. You would connect one RGB Hub to LED 1 and one RGB Hub to LED 2 on the Commander Pro, or Lighting Node Pro. Then on whatever device you connect it to you have to set the correct fan types up on each Hub, In the Lighting setup tab and then set the RGB in the appropriate Lighting Channel tabs.
