Intel Desktop Board D845HV/D845WN Technical Product Specification  NOTE If you install a CNR card that cannot support a multichannel audio upgrade, the D845HV and D845WN boards' integrated audio codec will be disabled. This only applies to D845HV and D845WN boards that have both the onboard audio subsystem and a CNR.  NOTE The brand and type of audio codec used on the CNR card must match that of the D845HV/D845WN boards' codec (Analog Devices AD1885). For information about Obtaining the CNR specification Refer to Section 1.5, page 18 1.13 Hardware Management Subsystem The hardware management features enable the boards to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features, including the following: • Fan monitoring • Thermal and voltage monitoring • Chassis intrusion detection For information about The WfM specification Refer to Section 1.5, page 18 1.13.1 Hardware Monitor Component (Optional) The hardware monitor component provides low-cost instrumentation capabilities. The features of the component include: • Internal ambient temperature sensing • Remote thermal diode sensing for direct monitoring of processor temperature • Power supply monitoring (+5 V, +3.3 V, +1.5 V, 3.3 VSB, Vccp) to detect levels above or below acceptable values • SMBus interface 1.13.2 Fan Monitoring The SMSC LPC47M142 I/O controller provides two fan tachometer inputs. Monitoring can be implemented using third-party software.
