Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:
• 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.
• Thermal sensors in the processor and Intel H67 PCH, as well as near the processor
voltage regulators and system memory.
• Monitoring of system voltages to detect levels above or below acceptable values
• Thermally monitored closed-loop fan control for all fans that can adjust fan speed
as needed.

Fan Monitoring

Fan monitoring can be observed via the BIOS Setup program, Intel
or third-party software.

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 1 for
the location of the chassis 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)
• +5 V standby power indicator LED
• Wake from USB
• PCI Express WAKE# signal support
• Wake from CIR

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.
