Desktop Board Features 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 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 a 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 18 for the location of the chassis intrusion header. 23
