The measured ambient temperature locally surrounding the processor. The
ambient temperature should be measured just upstream of a passive heatsink
or at the fan inlet for an active heatsink.
The case temperature of the processor, measured at the geometric center of
the topside of the IHS.
The ambient air temperature external to a system chassis. This temperature
is usually measured at the chassis air inlets.
Heatsink temperature measured on the underside of the heatsink base, at a
location corresponding to
The maximum case temperature as specified in a component specification.
Case-to-ambient thermal characterization parameter (psi). A measure of
thermal solution performance using total package power. This is defined as:
(T
– T
) / Total Package Power.
