In general, Thermal Cruise
The following figures illustrate two examples of Thermal Cruise
(3) If the temperature falls below the low end (e.g., 52 °C), fan output decreases slowly to zero or to a
specified “stop value”. This stop value is enabled by Bank0 Index12h, bits 5 ~ 4, and the value itself is
specified in Bank0 Index 08h and Index 09h. The fan remains at the stop value for the period of time defined
in Bank0 Index 0Ch and Index 0Dh.

if the current temperature is higher than the high end, increase the fan speed;
if the current temperature is lower than the low end, decrease the fan speed;
otherwise, keep the fan speed the same.
