Thermaltake Riing 12 RGB (not premium) voltage?

[powerpt]

I have a question... So, my mobo(MSI Z370-A PRO) fan header only supports up to 12V, so if I connect the three fans to the analog controller, and then connected the controller to the fan header, wouldnt it use more than 12V and damage the mobo?
Sorry for the dumb question, I'm going to build my pc next month and I wanna make sure everything will be ok ahaha

Voltage on fans in constant, current changes.
Now this is a tricky question, how much can the fan header output amps? Top tier motherboards (some of them unknown which) can up to 3A, but i guess your can up to 1A.
If the 3pin fan header can controll via voltage then connect to them.
