Intel Desktop Board DH67CF Product Guide Hardware Monitoring and Fan Speed Control The features of the hardware monitoring and fan speed control include: • Smart fan control provided by the legacy I/O controller, delivering acoustically- optimized thermal management. Fan speed controllers and sensors are integrated into the legacy I/O controller. • Thermal sensors in the processor and Intel H67 PCH, as well as near the processor voltage regulators and system memory. • Monitoring of system voltages to detect levels above or below acceptable values • Thermally monitored closed-loop fan control for all fans that can adjust fan speed as needed. Fan Monitoring Fan monitoring can be observed via the BIOS Setup program, Intel® Desktop Utilities, or third-party software. Chassis Intrusion The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch on the chassis that can be connected to the chassis intrusion header on the Desktop Board. See Figure 1 for the location of the chassis intrusion header. Power Management Power management is implemented at several levels, including software support through the Advanced Configuration and Power Interface (ACPI) and the following hardware support: • Power connectors • Fan headers • LAN wake capabilities • Instantly Available PC technology (Suspend to RAM) • +5 V standby power indicator LED • Wake from USB • PCI Express WAKE# signal support • Wake from CIR Software Support ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the Desktop Board requires an operating system that provides full ACPI support. 22
