Chaining together Pure Plus 12 Fans

[RecyclopsReveng3]

Hey there, 

So I am overhauling my PC this week. I bought 3-3 packs of the Pure Plus 12 RGB fans. Each pack comes with one of the controllers. Now before I start ripping my PC apart, I want to make sure I am able to do what I'd like to do. I was flipping through the instruction manual and unless I read it incorrectly, the controller box/s needs to be connected to a USB header. Currently I'm unable to use the USB header (my motherboard only has one ASUS Hero Maximus IX) as my Corsair AIO is hooked up to it. However, I am getting rid of the Corsair AIO so that USB header will available again. However, I am going to need to run 2 of the controller boxes so I can run 9 fans. I noticed that there is a bridge that comes with the kit. So if I use the bridge, does only 1 controller need to be plugged into the USB header? Do I NEED to use the USB header at all? There's so many cables with these things and unfortunately someone moved/threw away my instructions before I got to finish reading them. I have the other 2 packs coming in tomorrow so I can read through them but I figured I'd ask here before I tear down my PC.
