Figure 11 Linear mode fan control illustration-2
a. Once the temperature is lower than 40°C, the lowest fan speed keeps in 3,000 rpm (50% of full
speed).
b. Once the temperature is over 40°C,50°C and 60°C, the fan speed will vary from 3,000 to 4,800
rpm almost linearly with the temperature variation because the temp.-fan speed monitoring flash
interval is 1sec.
c. Once the temperature goes over 70°C, the fan speed will directly increase to full speed 6,000
rpm.
d. If the hysteresis is 5°C (default is 4°C), once the temperature becomes lower than 65°C (instead
of 70°C), the fan speed wull reduce from full speed and decrease linearly with the temperature.
