@LeDoyen thank you for your reply, I have installed Thermal Radar 3, software from Asus which has worked so far with all the fans I have connected directly to the motherboard, both PWM (4 pins) and DC (3 pins).
By connecting the Corsair HUB, however, I cannot manage the fans, either individually or all together.
I note that the HUB supplied with the CORSAIR 7000D AIRFLOW has a 3 pin output in a 4 pin connector, I don't understand why?
