OK, still a bit confused but i think i am learning. So the SP120 fans are not compatible on the same RGB LED Fan Hub (that came with the Crystal Series 570X case. Its sounds like in order to be able to have RGB fan control for both my SP120 case fans and the ML140 fans that came with my H115i RGB Platnum Pro, i would need to purchase a commander pro and connect via the USB port. Is this correct?
So for now, i can remove the RGB LED cables for the 2 ML140 fans from the RGB LED Fan Hub and just have the SP120 RGB pro fans plugged into ports 1, 2, and 3. Do i just leave the ML140 RGB LED cables unplugged for now? Will that impact their performance in anyway outside of no lights?
