1.11.1 Hardware Monitor Component

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 (+12, +5, +3.3, +2.5, 3.3 VSB, Vccp) to detect levels above or below
acceptable values
•
SMBus interface
1.11.2 Fan Control and Monitoring
The SMSC LPC47M102 I/O controller provides one fan tachometer input. The enhanced thermal
monitor and fan control device provides two fan sense inputs and two fan control outputs.
Monitoring and control can be implemented using third-party software.
