Product Description 1.11.1 Hardware Monitoring and Fan Control ASIC The features of the hardware monitoring and fan control ASIC include: • Internal ambient temperature sensor • Two remote thermal diode sensors for direct monitoring of processor temperature and ambient temperature sensing • Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.5 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 • SMBus interface For information about The location of the fan connectors and sensors for thermal monitoring Refer to Figure 15, page 38 1.11.2 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 connector. When the chassis cover is removed, the mechanical switch is in the closed position. 1.11.3 Fan Monitoring Fan monitoring can be implemented using Intel® Desktop Utilities or third-party software. The level of monitoring and control is dependent on the hardware monitoring ASIC used with the board. For information about The functions of the fan connectors Refer to Section 1.12.2.2, page 42 37

1.11.1
Hardware Monitoring and Fan Control ASIC
The features of the hardware monitoring and fan control ASIC include:
•
Internal ambient temperature sensor
•
Two remote thermal diode sensors for direct monitoring of processor temperature and ambient
temperature sensing
•
Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.5 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
•
SMBus interface
For information about
Refer to
The location of the fan connectors and sensors for thermal monitoring
Figure 15, page 38
1.11.2
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
connector.
When the chassis cover is removed, the mechanical switch is in the closed position.
1.11.3
Fan Monitoring
Fan monitoring can be implemented using Intel
®
Desktop Utilities or third-party software.
The
level of monitoring and control is dependent on the hardware monitoring ASIC used with the
board.
