Intel Desktop Board DG33FB Product Guide

Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:

Monitoring of power supply voltages to detect levels above and below acceptable values

Intel Quiet System Technology fan speed control, delivering acoustically-optimized thermal management

NOTE

Memory must be installed in the Channel A, DIMM 0 socket to enable Intel Quiet System Technology.

Fan speed controllers and sensors integrated into the ICH9DH

Thermal sensors in the processor, GMCH, and ICH9DH, plus an onboard remote sensor

Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed or switch the fans off as needed

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the Desktop Board. See Figure 23 for the location of the chassis intrusion header.

Power Management Features

Power management is implemented at several levels, including:

Software support through the Advanced Configuration and Power Interface (ACPI)

Hardware support:

Power connectors

Fan headers

LAN wake capabilities

Instantly Available PC technology (Suspend to RAM)

+5 V standby power indicator LED

Wake from USB

Wake from PS/2 keyboard/mouse

Power Management Event signal (PME#) wakeup support

WAKE# signal wake-up support

ENERGY STAR qualified

ACPI

ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the Desktop Board requires an operating system that provides full ACPI support.
