(4) If the current temperature falls below (Target Temperature - Temperature Tolerance), the fan
(5) If the current temperature is always lower than (Target Temperature X - Temperature Tolerance),
Temperature Tolerance), or Target Temperature 2. This process repeats whenever the current
temperature is higher than (Target Temperature X ± Temperature Tolerance) or until the fan
speed reaches its maximum speed.
speed falls 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.This is
illustrated in the figure below.
If the current temperature falls lower than (Target Temperature 1 - Temperature Tolerance), the
fan speed is reduced one step again, and the target temperature shifts to (Target Temperature 1
- Temperature Tolerance), or Target Temperature 2. This process repeats whenever the current
temperature is lower than (Target Temperature X - Temperature Tolerance) or until the fan
speed reaches its minimum speed.
the fan speed decreases slowly to zero or to a specified stop value. The stop value is enabled by
register Bank0 Index 12h, bit 4 and bit 6, and the stop value is specified in Bank0 Index 09h and
Index 64h. The fan remains at the stop value for the period of time defined in Bank0 Index 0Dh
and Index 66h.
