FAN Control and Monitoring
Fan Speed Monitoring
AST2050 senses all fans in threshold base through its internal or external tachometer sensor W83793G. All of sensors
support LNCT and LCT assertion and de-assertion. Thermal engineers also need to define these values. Below is the table
of fan speed thresholds.

Bus Error Detection
PCI Bus Error Detection
This feature will be done by BIOS. BIOS will record events in SEL.
Memory Bus Error Detection
This feature will be done by BIOS. BIOS will record events in SEL.
QPI Error Detection
This feature will be done by BIOS. BIOS will record events in SEL.
Processor Error Detection
Thermal Trip / Processsor Hot
Thermal Trip and Processor Hot can be detected by GPIO. When error is detected, the event will be added to SEL and the
supported action will be executed in PEF.
