Desktop Board Features
Hardware Monitoring and Fan Speed Control
The features of the hardware monitoring and fan speed control include:
•Monitoring of power supply voltages to detect levels above and below acceptable values
•Intel Quiet System Technology fan speed control, delivering
NOTE
Memory must be installed in the Channel A, DIMM 0 socket to enable Intel Quiet System Technology.
•Fan speed controllers and sensors integrated into the ICH9DO
•Thermal sensors in the processor, GMCH, and ICH9DO, 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 its temperature rises above this point.
•Thermally monitored
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 23 on page 51 for the location of the chassis intrusion header.
Power Management Features
Power management is implemented at several levels, including:
•Software support through the Advanced Configuration and Power Interface (ACPI)
•Hardware support:
⎯Power connectors
⎯Fan headers
⎯LAN wake capabilities
⎯Instantly Available PC technology (Suspend to RAM)
