1.11 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
1.11.1
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 ICH10D
•
Remote thermal diode sensor for ambient temperature sensing
•
Thermal sensors in the processor, 82B43 GMCH, and 82801JD ICH10D
•
Power supply monitoring of five voltages (+5 V, +12 V, +3.3 V, +1.125 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 according to thermal conditions
1.11.2
Fan Monitoring
Fan monitoring can be implemented using Intel
software.

1.11.3
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.
