Product Description 1.11 Hardware Management Subsystem The hardware management features enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features, including the following: • Fan monitoring and control • Thermal and voltage monitoring • Chassis intrusion detection 1.11.1 Hardware Monitoring and Fan Control The features of the hardware monitoring and fan control include: • Intel Quiet System Technology, delivering acoustically-optimized thermal management • Fan speed control controllers and sensors integrated into the ICH8DO • Four thermal sensors (processor, 82Q965 GMCH, 82801HO ICH8DO, and a remote thermal sensor) • Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.25 V, and +VCCP) to detect levels above or below acceptable values • Thermally monitored closed-loop fan control, for all three fans, that can adjust the fan speed or switch the fans on or off as needed 1.11.2 Fan Monitoring Fan monitoring can be implemented using Intel Desktop Utilities or third-party software. For information about The functions of the fan headers Refer to Section 1.12.2.2, page 44 1.11.3 Chassis Intrusion and Detection The board supports a chassis security feature that detects if the chassis cover is removed. The security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion header. When the chassis cover is removed, the mechanical switch is in the closed position. For information about The location of the chassis intrusion header Refer to Figure 16, page 58 39

1.11
Hardware Management Subsystem
The hardware management features enable the board to be compatible with the Wired
for Management (WfM) specification.
The board has several hardware management
features, including the following:
•
Fan monitoring and control
•
Thermal and voltage monitoring
•
Chassis intrusion detection
1.11.1
Hardware Monitoring and Fan Control
The features of the hardware monitoring and fan control include:
•
Intel Quiet System Technology, delivering acoustically-optimized thermal
management
•
Fan speed control controllers and sensors integrated into the ICH8DO
•
Four thermal sensors (processor, 82Q965 GMCH, 82801HO ICH8DO, and a remote
thermal sensor)
•
Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.25 V, and
+VCCP) to detect levels above or below acceptable values
•
Thermally monitored closed-loop fan control, for all three fans, that can adjust the
fan speed or switch the fans on or off as needed
1.11.2
Fan Monitoring
Fan monitoring can be implemented using Intel Desktop Utilities or third-party
software.
For information about
Refer to
The functions of the fan headers
Section 1.12.2.2, page 44
1.11.3
Chassis Intrusion and Detection
The board supports a chassis security feature that detects if the chassis cover is
removed.
The security feature uses a mechanical switch on the chassis that attaches
to the chassis intrusion header.
When the chassis cover is removed, the mechanical
switch is in the closed position.
