Kindly Remind:
Only the fan on CPU Fan channel is used for monitoring. 
All connected fans are following the same PWM signa, speed control is the same for all fans when use fan controller software like AI stuite/Xspert FAN and EASY TUNE, etc.
PWM capable connectors must necessarily be 4-pin, but not all 4-pin motherboard connectors implement or enable the PWM signal modulation by default. 
Please carefully consult your motherboard documentation in this respect. 
This is only a fan hub, NOT fan speed controller.
Only 4-pin PWM fans speed can be adjusted by fan controller software.
3-pin fan would run in full speed, can not be adjusted when connect.
