Term
Description
Bypass
Bypass is the area between a passive heatsink and any object that can act to form a
duct. For this example, it can be expressed as a dimension away from the outside
dimension of the fins to the nearest surface.
DTS
Digital Thermal Sensor reports a relative die temperature as an offset from TCC
activation temperature.
FSC
Fan Speed Control
IHS
Integrated Heat Spreader: a component of the processor package used to enhance the
thermal performance of the package. Component thermal solutions interface with the
processor at the IHS surface.
ILM
Independent Loading Mechanism provides the force needed to seat the 1366-LGA land
package onto the socket contacts.
LGA1366 socket
The processor mates with the system board through this surface mount, 1366-contact
socket.
PECI
The Platform Environment Control Interface (PECI) is a one-wire interface that provides
a communication channel between Intel processor and chipset components to external
monitoring devices.
CA
Case-to-ambient thermal characterization parameter (psi). A measure of thermal
solution performance using total package power. Defined as (T
CASE
– T
LA
) / Total
Package Power. Heat source should always be specified for measurements.
CS
Case-to-sink thermal characterization parameter. A measure of thermal interface
material performance using total package power. Defined as (T
CASE
– T
S
) / Total
Package Power.
SA
Sink-to-ambient thermal characterization parameter. A measure of heatsink thermal
performance using total package power. Defined as (T

) / Total Package Power.
T
CASE
The case temperature of the processor measured at the geometric center of the topside
of the IHS.
T
CASE
