15 C

 

This value controls the temperature of the

 

 

 

 

 

23 C

 

 

 

 

 

 

 

ACPI active trip point - the point in which

 

 

 

 

 

 

 

 

Active Trip Point

 

 

 

the OS will turn on the CPU fan (connector

 

 

 

 

55 C

 

 

 

 

 

 

 

on PCB). If DTS is enabled only values below

 

 

 

 

 

63 C

 

 

 

 

 

 

 

97°C are valid.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

119 C

 

 

 

 

 

 

 

Disabled

 

 

This value controls the temperature of the

 

 

 

 

 

15 C

 

 

ACPI passive cooling trip point - the point in

 

 

Passive Cooling Trip Point

 

 

23 C

 

 

which the OS will start to throttle the CPU,

 

 

 

 

 

 

 

either by TM1 or TM2. If DTS is enabled only

 

 

 

 

 

119 C

 

 

values below 97°C are valid.

 

 

 

 

 

POR

 

 

 

 

 

 

 

 

15 C

 

 

This value controls the temperature of the

 

 

Critical Trip Point

 

 

23 C

 

 

ACPI critical trip point - the point in which

 

 

 

 

 

 

the OS will shut down the system.

 

 

 

 

 

 

 

 

 

 

 

 

119 C

 

 

POR means 100°C for all Intel processors.
