the CPU. The onboard chassis thermal circuitry can monitor the overall
system temperature and alert users when the chassis temperature is too
high.
CPU Fan Auto-Off in Sleep Mode
The CPU fan activates when the power is turned on. It continues to operate
when the system enters Standby mode. When in sleep mode, the CPU will
not run at full power, thereby generating less heat.
CPU Overheat/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat/Fan Fail
warning function in the BIOS. This allows the user to define an overheat
temperature. When this temperature is exceeded or when a fan failure
occurs, then, the Overheat/Fan Fail warning LED is triggered.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator can auto-detect and regulate power
supply to the CPU. This will allow the regulator to run cooler and thus make
the system more stable.
TM2/CPU VRM Overheat
When the CPU reaches 90

turned on. The CPU wii slow down. When this happens, you can go to the
Health Monitor Setting in the BIOS to reset CPU Overheat Temperature.
