There are two pairs of temperature sensors and fan outputs in S

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
output according to the current temperature. Three conditions may occur:

•
•
(1) If the temperature still exceeds the high end, fan output increases slowly. If the fan is operating at full
speed but the temperature still exceeds the high end, a warning message is issued to protect the system.
(2) If the temperature falls below the high end (e.g., 58 °C) but remains above the low end (e.g., 52 °C), fan
output remains the same.
