Product Description

1.12 Hardware Management Subsystem

The hardware management features enable the board to be compatible with the Wired

for Management (WfM) specification. The board has several hardware management

features, including the following:

•

Fan monitoring and control

•

Thermal and voltage monitoring

•

Chassis intrusion detection

1.12.1

Hardware Monitoring and Fan Control

The features of the hardware monitoring and fan control include:

•

Intel Quiet System Technology, delivering acoustically-optimized thermal

management

•

Fan speed control controllers and sensors integrated into the ICH9R

•

Thermal sensors in the processor, 82P35 MCH, and 82801IR ICH9R

•

Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.25 V, and

+VCCP) to detect levels above or below acceptable values

•

Thermally monitored closed-loop fan control, for all three fans, that can adjust the

fan speed or switch the fans on or off as needed

1.12.2

Fan Monitoring

Fan monitoring can be implemented using Intel® Desktop Utilities or third-party

software.

1.12.3

Chassis Intrusion and Detection

The board supports a chassis security feature that detects if the chassis cover is

removed. The security feature uses a mechanical switch on the chassis that attaches

to the chassis intrusion header. When the chassis cover is removed, the mechanical

switch is in the closed position.
