Thermal Management
5.3.1 Fan Speed Control Scheme with Digital Thermal Sensor
(DTS) 2.0
To simplify processor thermal specification compliance, the processor calculates the
DTS Thermal Profile from T
CONTROL
Offset, TCC Activation Temperature, TDP, and the
Thermal Margin Slope provided in the following table.
Note: TCC Activation Offset is 0 for the processors.
Using the DTS Thermal Profile, the processor can calculate and report the Thermal
Margin, where a value less than 0 indicates that the processor needs additional cooling,
and a value greater than 0 indicates that the processor is sufficiently cooled.

Notes:
1. Digital Thermal Sensor (DTS) based fan speed control is recommended to achieve optimal thermal performance.
2. Intel recommends full cooling capability at approximately the DTS value of -1, to minimize TCC activation risk.
3. For example, if T
CONTROL
= 20 ºC, Fan acceleration operation will start at 80 ºC (100 ºC - 20 ºC).
