Notes: 1.

ΨCA at "DTS = TCONTROL" is applicable to systems that have an internal TRISE (TROOM temperature

 

to Processor cooling fan inlet) of less than 10 °C. In case the expected TRISE is greater than 10

 

°C, a correction factor should be used as explained below. For each 1 °C TRISE above 10 °C, the

 

correction factor (CF) is defined as CF = 1.7 / (processor TDP)

 

2.

Example: A chassis TRISE assumption is 12 °C for a 95 W TDP processor:

 

 

CF = 1.7 / 95 W = 0.018 /W

 

 

 

For TRISE > 10 °C

ΨCA at TCONTROL = (Value provide in Column 2) – (TRISE – 10) * CF ΨCA = 0.627 – (12 – 10) * 0.018 = 0.591 °C/W

In this case, the fan speed should be set slightly higher, equivalent to ΨCA = 0.591 °C/W

To simplify processor thermal specification compliance, the processor calculates the DTS Thermal Profile from TCONTROL 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. Refer to the processor Thermal Mechanical Design Guidelines (TMDG) for additional information (see Related Documents).
