i figure out the problem 😁
every controller is come with 5 plug for fans
if you used only 3 it will shows warning so i but all 5 fans in 1 controller it is work and blue light is coming in TT RGB app
so the last fan in controller no.2 it is shows warning in red color
😡 Quaz is why they sell us a 3 fan with controller for 5 fan and it is not working with
best regard
