Chapter 1: Introduction
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
TM2/CPU VRM Overheat
When the CPU reaches 900 C and above (Overheat), the CPU will slow down and CPU Voltage will decrease to reduce CPU power consumption and VRM heat dissipation.
When CPU temperature reaches 900 C and above (*Default), the system will go into the throttling state. The Overheat LED and Alarm Buzzer will be 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.
1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines a flexible and abstract hardware interface that pro- vides a standard way to integrate power management features throughout a PC system, including its hardware, operating system and application soft- ware. This enables the system to automatically turn on and off peripherals
