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
• Smart fan control provided by the legacy I/O controller, delivering acoustically-
optimized thermal management. Fan speed controllers and sensors are integrated
into the legacy I/O controller.
• A thermal sensor in the processor
• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed
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 24 for
the location of the c
hassis intrusion header.
Power Management
Power management is implemented at several levels, including software support
through the Advanced Configuration and Power Interface (ACPI) and the following
hardware support:
• Power connectors
• Fan headers
• LAN wake capabilities
• Instantly Available PC technology (Suspend to RAM)
• Wake from USB
• Power Management Event signal (PME#) wakeup support
• WAKE# signal wake-up support
• Wake from Consumer IR
Software 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.
