The pwr fan header works full speed all the time.
3 of the others cpu1 cpu2 and sys fan 1 can be pwm activated to full speed occurring at a preset cpu temp.cpu1 and sysfan1 have to be 4 pin fans,cpu2 can be 3 pin.
The other fans can be speed adjusted to a set lvl in uefi or axtu from windows.

Parsec I think it was recently got a bios update for his board where he has even more fine adjustment of the low speeds of the cpu temp controlled fans.
