Hello, I have two 480 radiators in my cooling loops. I installed Ring RGB fans in all 8 positions. It required 2 packs of 3 and 2 individual fans, There are toal of 4 fan controllers involved (they control color of lighting). Each controller is capable of controlling up to 3 fans. There is also unused connector on the controller. Is there a way to color-synchronize several controllers (may be at least two)? Maybe unused connector have a special cable that I can use to interconnect controllers? Thanks for you help, Vitali Fridman
