1.11.3 Fan Monitoring
Fan monitoring can be implemented using Intel
party software. The level of monitoring and control is dependent on the hardware monitoring ASIC
used with the Desktop Board.

1.11.4 Fan Speed Control (Intel
®
Intel
Precision Cooling Technology automatically adjusts the processor fan speed based on the
processor thermal diode temperature and adjusts the chassis fan speeds depending on the system
temperature. System fan noise may be reduced by operating controlled chassis and processor fans
at the minimum necessary speeds.
The processor and chassis fan speed control features can be disabled independently through the
desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at
full speed if it is not a self controlled fan. It is recommended that processor fan speed control
remain enabled (default BIOS setting) when using the processor fan heat-sink included with Intel
boxed processors. Disabling the chassis fan speed control results in chassis fans always operating
at full speed. The chassis fan speed control feature should be disabled if a self-controlled chassis
fan is attached to any controlled chassis fan header.
The overall system noise reduction will vary based on system configuration and environment.
1.11.5 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.
1.12 Power Management
Power management is implemented at several levels, including:
•
Software support through Advanced Configuration and Power Interface (ACPI)
•
Hardware support:
⎯ Power connector
⎯ Fan connectors
⎯ LAN wake capabilities
⎯ Instantly Available PC technology
⎯ Resume on Ring
