Frangus

I am planning on using 3 Riing fans in my build. I have a Phanteks Evolv ATX Tempered Glass which comes with a pre installed fan hub. What i am wondering is, can i connect the Riing hub through this fan hub or would i have to bypass it and go straight to the motherboard. The connectors on the fan hub are all 3 pin which is why im not sure if it will work through this. If i can use the fan hub, would i connect the 3 pins on the Riing 4 pin connector and leave out the ground? Thanks for the help.
