Desktop Board Features 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 intrusion header. 23
