I have a b350-f rog strix motherboard and I have almost the entire build ready except the cpu, which I’m getting from a friend. I just got these new Corsair masterfan pros (120s) and I like assembling things for practice so I set them up and powered the motherboard but the fans won’t spin nor will the rgb turn on (with or without an rgb hub). Not only that but when I plugged in my case leds they won’t turn on either. Is it because I don’t have a cpu or is my motherboard messed up?
