http://ssiforum.oaktree.com/ 1.2 Definition of Terms Table 1-2 Terms and Descriptions (Sheet of 2) 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 IMON The current monitor input to the CPU The VRM tells the CPU how much current it is drawing LGA1366 socket The processor mates with the system board through this surface mount, 1366-land 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 ΨCA Case-to-ambient thermal characterization parameter (psi) A measure of thermal solution performance using total package power Defined as (TCASE – TLA) / Total Package Power Heat source should always be specified for Ψ measurements ΨCS Case-to-sink thermal characterization parameter A measure of thermal interface material performance using total package power Defined as (TCASE – TS) / Total Package Power ΨSA Sink-to-ambient thermal characterization parameter A measure of heatsink thermal performance using total package power Defined as (TS – TLA) / Total Package Power TCASE The case temperature of the processor, measured at the geometric center of the topside of the IHS TCASE_MAX The maximum case temperature as specified in a component specification Intel® Xeon® Processor C5500/C3500 Series and LGA1366 Socket Thermal/Mechanical Design Guide August 2010 Order Number: 323107-002US Introduction Table 1-2 Terms and Descriptions (Sheet of 2) Term Description TCC Thermal Control Circuit: Thermal monitor uses the TCC to reduce the die temperature by using clock modulation and/or operating frequency and input voltage adjustment when the die temperature is very near its operating limits TCONTROL Tcontrol is a static value below TCC activation used as a trigger point for fan speed control TDP Thermal Design Power: Thermal solution must be designed to dissipate this target power level TDP is not the maximum power that the processor can dissipate Thermal Monitor A power reduction feature designed to decrease temperature after the processor has reached its maximum operating temperature Thermal Profile Line that defines case temperature specification of a processor at a given power level TIM Thermal Interface Material: The thermally conductive compound between the heatsink and the processor case This material fills the air gaps and voids, and enhances the transfer of the heat from the processor case to the heatsink TLA 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 TSA The system ambient air temperature external to a system chassis This temperature is usually measured at the chassis air inlets U A unit of measure used to define server rack spacing height 1U is equal to 1.75 in, 2U equals 3.50 in, etc Đ August 2010 Order Number:
