Hardware Management Features
The hardware management features of Desktop Board DG45ID enable the board to be
compatible with the Wired for Management (WfM) specification. The board has several
hardware management features including the following:
• Fan speed monitoring and control
• Thermal and voltage monitoring
• Chassis intrusion detection
Fan Speed, Thermal, and Voltage Monitoring and
Control
The board’s fan speed, thermal, and voltage monitoring and control features include
the following:
• 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.
• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed according to thermal conditions.
• Fan speed controllers and sensors integrated into the ICH10R
• Thermal sensors in the processor, GMCH, and ICH10R, plus an onboard remote
sensor
NOTE
The minimum thermal reporting threshold for the GMCH is 66 °C. The GMCH thermal
sensor will display 66 °C until the temperature rises above this point.
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 21 for
the location of the c
h
assis intrusion header.
