The measured ambient temperature locally surrounding the processor. The
ambient temperature should be measured just upstream of a passive
A
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.
C
The ambient air temperature external to a system chassis. This
temperature is usually measured at the chassis air inlets.
E
Heatsink temperature measured on the underside of the heatsink base, at
a location corresponding to
S
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. Defined as
