(3) If the current temperature is higher than (Target Temperature + Temperature Tolerance), fan
speed rises one step. The step is the value in the CPUFANOUT Output Value Select Register,
Bank0 Index 03h or Index 61h. In addition, the target temperature shifts to (Target Temperature +
Temperature Tolerance), creating a new target temperature, named Target Temperature 1 in this
figure.
