Sensor Based Thermal Specification
The sensor based thermal specification consists of two parts. The first is a thermal
profile that defines the maximum TTV T
CASE
as a function of TTV power dissipation. The
thermal profile defines the boundary conditions for validation of the thermal solution.
The second part is a defined thermal solution performance (
Ψ
CA
) as a function of the
DTS value as reported over the PECI bus when DTS is greater than T
CONTROL
. This
defines the operational limits for the processor using the TTV validated thermal
solution.
