F1OV – F8OV also has a special characteristic- sequential power-on respectively. This function is used
to avoid over loads of the system current when the system is powered-on and all fans start to spin. The
W83795G/ADG takes 0.1 second (12.5ms intervals for 8 fans) to turn on all of the fans one by one.

F1OPFP – F8OPFP control the FANCTL1-FANCTL8 fan output frequency in the PWM mode. A wide
range of clocks can be selected to satisfy customer needs. The default output frequency is 26 KHz.
FANCTL3-FANCTL8 functions are not for W83795ADG.
