Core™2 Quad Processor Q6000
The measured ambient temperature locally surrounding the processor. The ambient
temperature should be measured just upstream of a passive heatsink or at the fan
A
inlet for an active heatsink.
The case temperature of the processor, measured at the geometric center of the
C topside of the IHS.
The ambient air temperature external to a system chassis. This temperature is usually
E measured at the chassis air inlets.
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.
Working fluid temperature as it leaves the pump (or enters the heat exchanger).
Case-to-ambient thermal characterization parameter (psi). A measure of thermal
solution performance using total package power. Defined as (T
Power.
CA

Case-to-sink thermal characterization parameter. A measure of thermal interface
material performance using total package power. Defined as (T
Power.

Sink-to-ambient thermal characterization parameter. A measure of heatsink thermal
performance using total package power. Defined as (T
