3.7.14.1.2 System Fan Mode: Thermal Cruise
Step up time: The amount of time fan takes to increase its value by one step. (Units are intervals
of 0.1 second). 10 x 0.1 sec = 1 sec as default.
Step down time: The amount of time fan takes to decrease its value by one step. (Unite are
intervals of 0.1 second). 10 x 0.1 sec = 1 sec as default.
The max and min value of “Fan target Temperature”, “tolerance value”, “stop duty”, “startup
value” can be set from 0 to 127.
Thermal Cruise mode controls the fan speed to keep the temperature in a specified range. First,
this range is defined in BIOS by a temperature and the interval (e.g., 55 °C ± 3 °C). As long as
the current temperature remains below the low end of this range (i.e., 52 °C), the fan is off. Once
the temperature exceeds the low end, the fan turns on at a speed defined in BIOS (e.g., 20%
output). Thermal Cruise mode then controls the fan output according to the current temperature.
