Introduction

Environmental Temperature Control via Supero DoctorIII

The thermal control sensor monitors the CPU temperature in real time and

will increase the speed of the thermal control fan whenever the CPU tem-

perature exceeds a user-defined threshold. The overheat circuitry runs

independently from the CPU. It can continue to monitor for overheat condi-

tions even when the CPU is in sleep mode. Once it detects that the CPU

temperature is too high, it will automatically increase the speed of the ther-

mal control fan to prevent any overheat damage to the CPU. The onboard

chassis thermal circuitry can monitor the overall system temperature and

alert users when the chassis temperature is too high.

TM2/CPU VRM Overheat

When the CPU reaches 70

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 78

C and above (*Default), the system will

go into the throttling state. The Overheat LED and Alarm Buzzer will be

turned on. The CPU will slow down. When this happens, you can go to the

Health Monitor Setting in the BIOS to reset CPU Overheat Temperature.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning

function in the BIOS. This allows the user to define an overheat tempera-

ture. When this temperature is exceeded, the warning LED is triggered and

the fans will speed up.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to

120W current and auto-sense voltage IDs ranging from .8375V to 1.6V.

This will allow the regulator to run cooler and thus make the system more

stable.
