Intel Desktop Board DG35EC 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:
• Fan speed control controllers and sensors integrated into the ICH8
• Four thermal sensors (processor, 82G35 GMCH, 82801HB ICH8, 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
1.12.2

Fan Monitoring

Fan monitoring can be implemented using Intel
software.

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.
