Hello,

This is the straight situation: Z370 taichi, latest bios. 5 non-pwm fans connected to the motherboard with dc settings from bios. Cpu fan cannot be controlled,optional and chassis 1-2-3 can with the asrock utility and they follow the graph i gave them.

Now i changed Cpu fan with a pwm one. Cpu now can follow my orders, chassis 1-2-3 can follow my orders, optional doesn't follow my orders anymore. No sense to me.

Please suggest me how can i solve the issue... thank you
