(3) If the current temperature is higher than (Target Temperature + Temperature Tolerance), fan
Temperature ± Temperature Tolerance), the fan speed remains constant.
speed rises one step. The step is the value in the CPUFANOUT Output Value Select Register,
Bank0, Index 03h. In addition, the target temperature shifts to (Target Temperature + Temperature
Tolerance), creating a new target temperature, named Target Temperature 1 in this figure.
