Additional Sensors
The SDR for Processor 0 includes three separate functions
:
presence detect
IERR
processor voltage mismatch
Fan Control
Individual fan speed is controlled by the HMC, based on temperature
and configuration information. This allows fans to run slower in most
circumstances, thus making the machine quieter.
Sense Power State
Zircon senses power state using signal pins from the ICH2.
This is used for fan control and indicating power state on the status
LED.
