I’m getting ready to build my first pc, I have the 3500x RS-R case which came with 3 RS120-R fans. I’m thinking about getting a few more fans and a controller for them. I have seen the Commander Duo but I’m slightly confused as to whether I would need the iCue Link system hub as well, if I were to buy more of just regular rs120-r fans, not iCue fans. Thanks.
