Hardware Management Features
The hardware management features of Intel Desktop Board DB43LD 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 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 ICH10D
• Thermal sensors in the processor, GMCH, and ICH10D, 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. A mechanical switch on the chassis can be connected to the chassis
intrusion header on the Desktop Board. See Figure 20 for the location of the chassis
