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
1.11.1
Hardware Monitoring and Fan Control
The features of the hardware monitoring and fan control include:
•
Fan speed control controllers and sensors integrated into the legacy I/O controller
•
Remote thermal diode sensor for ambient temperature sensing
•
Thermal sensors in the processor, 82G31 GMCH, and ICH7
•
Power supply monitoring of three voltages (+5 V, +12 V, 3.3 V) to detect levels
above or below acceptable values
•
Thermally monitored closed-loop fan control, for both 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.
