I got the splitty4, and it came with a 4 pin fan connector do you know if that will work on the ultitube?

So technically I could get a rgbpx cable and connect the out on the ring to the splitty 4. Then use my corsair fans with rgb as well. If I connect the splitty 4 to the pump fan controller will I exceed the 25 watts on the pump?

I picked up the Ulititube 200mm d5 next pro, it came with a usb cable and rgbpx cable. I understand where the usb cable connects to, but does the rgbpx cable connect from the pump to the input on the ring? Will the splitty4 also work with the ultitube as well, I know that the ultitube only have 25 watts. Would that work with the splitty 4, because I can connect my Corsair AF120 Elite fans to it? I wish there were better instructions.
