I currently have 7 Riing Quad 14 fans connected to a TT SYNC controller. All fans spin as expected, but any fan I plug into the 3rd port (furthest away from the PWM) on any side of the TT SYNC will not light up. With all 3 ports in use on 2 sides, and 1 port in use on the 3rd side, I currently only have 5 out of 7 fans lighting up. All fans light up as expected as long as they aren't plugged into the 3rd port on the TT SYNC, so it seems to be an issue with the TT SYNC. Do I have a bad TT SYNC, or am I missing something?
