Intel Desktop Board DG41TX Technical Product Specification
1.12 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
1.12.1
Hardware Monitoring and Fan Control
The features of the hardware monitoring and fan control include:
•
SIO smart fan control, delivering acoustically-optimized thermal management
•
Fan speed control controllers and sensors integrated into the SIO
•
Three thermal sensors (processor, 82G41 GMCH, and 82801GB ICH7)
•
Power supply monitoring of five voltages (+5 Vsb, +5V, +12 V, +3.3 V, and
+VCCP) to detect levels above or below acceptable values
•
Thermally monitored closed-loop fan control, for both fans, that can adjust the fan
speed according to thermal conditions
1.12.2
Fan Monitoring
Fan monitoring can be implemented using third-party software. The level of
monitoring and control is dependent on the I/O controller used with the board.

1.12.3
Chassis Intrusion 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.
