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, delivering acoustically-optimized thermal management 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 ICH8 • Thermal sensors in the processor, GMCH, and ICH8 plus an onboard remote sensor • Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed or switch the fans off as needed Chassis Intrusion Detection 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 29 on page 55 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) ― +5 V standby power indicator LED ― Wake from USB ― Wake from PS/2 keyboard/mouse ― Power Management Event signal (PME#) wakeup support ― WAKE# signal wake-up support ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the desktop board requires an operating system that provides full ACPI support. 21
