Hardware Management
The hardware management features of Intel Desktop Board DH67GD enable the board
to be compatible with the Wired for Management (WfM) specification. The board has
several hardware management features including the following:
Fan speed monitoring and control
Thermal and voltage monitoring
Chassis intrusion detection
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
®
Desktop Utilities,
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 c
h
assis 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
