Example for PWM1 assigned to Zone 1:

■
In this case, the PWM1 duty cycle will be 50% at 50°C.
Since (Zone 1 Low Temp Limit) + (Zone 1 Range) = 50°C + 8°C = 58°C, the fan controlled by PWM1
will run at 100% duty cycle when the temperature of the Zone 1 sensor is at 58°C.
Since the midpoint of the fan control range is 54°C, and the median duty cycle is 75% (Halfway
between the PWM Minimum and 100%), PWM1 duty cycle would be 75% at 54°C.
Above (Zone 1 Low Temp Limit) + (Zone 1 Range), the duty cycle must be 100%.
The PWM frequency bits [3:0] determine the PWM frequency for the fan.
PWM Frequency Selection (Default =0011=29.3Hz)
Range Selection (Default =1100=32°C)
Zone 1 Low Temp Limit (Register 67h) is set to 50°C (32h).
Zone 1 Range (Register 5Fh) is set to 8°C (7h)
PWM1 Minimum Duty Cycle (Register 64h) is set to 50% (80h)
