Hardware Management Features
The hardware management features of Intel Desktop Board DG43NB 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 ICH10
• Thermal sensors in the processor, the MCH, and ICH10, plus an onboard remote
sensor
NOTE
The minimum thermal reporting threshold for the MCH is 66 °C. The MCH 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 20 for
the location of the c
h
assis intrusion header.
