I have the set of three Pure Plus 12 fans, I have had these for more than a year now. I received them as a gift and didn't realize they had controllable RGB when I first put them in my case. The problem is the controller is not being noticed by my pc. I have a Ryzen 7 2700x and a Gigabyte Aorus B450 mother board. I realized this problem a while ago and doing research that made me believe that I couldn't ever fix it. This is my last resort so please if anyone has any information please help.
