Hardware Management
The hardware management features of Desktop Board DX38BT 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:
• Monitoring of power supply voltages to detect levels above and below acceptable
values
• Intel
®
Precision Cooling Technology fan speed control, delivering acoustically-
optimized thermal management
• Thermal sensors in the processor, MCH, and ICH9R, plus an onboard remote
sensor
NOTE
The minimum thermal reporting threshold for the MCH is 66 °C. The MCH
thermal sensor will report 66 °C until its temperature rises above this point.
• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed or switch the fans off as needed
Intel
®
Precision Cooling Technology
Intel Precision Cooling Technology automatically adjust processor fan speed based on
the processor temperature and adjusts chassis fan speeds based on the internal
system temperature.
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 27 for
the location of the c
h
assis intrusion header.
