itsbmw, welcome to Tom's. There are Stickies at the top of each Forum, so please read them before posting.
From the
Core 2 Quad and Duo Temperature Guide:
http://www.tomshardware.com/forum/221745-29-core-quad-temperature-guide
Section 1: Introduction
Intel provides separate thermal specifications for
2 different sensor types; a single Case Thermal Diode located within the CPU die between the Cores, and
Digital
Thermal
Sensors located within each Core. The Case Thermal Diode measures
Tcase (
Temperature
Case), which is commonly known as CPU temp, and the
Digital
Thermal
Sensors measure
Tjunction (
Temperature
Junction), which is commonly known as Core temp. Since these sensors measure
2 distinct thermal levels, there is a constant temperature difference between them, which is referred to as
Tcase to
Junction Delta. C2Q`s have
1 Tcase and
4 Junction sensors, while C2D`s have
1 Tcase and
2 Junction sensors.
When listing Idle & Load test
Results, it's also necessary to list the
Variables as shown below:
Results
Tcase = Idle & Load
Tjunction = Idle & Load, hottest Core
Variables
Ambient = Room Temp
Chipset = Model
C2Q / C2D = Model
CPU Cooler = Model
Frequency = CPU Clock
Load = Test Program
Motherboard = Model
Stepping = Revision
Vcore = CPU Voltage

Section 8: Tools
Note 4: The software utility (
TAT)
Thermal
Analysis
Tool at maximum settings will simulate
100% Thermal Load, which would equal Prime95 at
114% Workload ~
5c hotter. This provides the most extreme testing available for CPU and system cooling efficiency. Since TAT is coded to measure Notebook temps, it identifies a C2D as Pentium M. As Notebooks have no
Integrated
Heat
Spreader, thermal scaling differs from desktop CPU`s, so TAT indicates ~
2c lower, and depending on
Variables, temps may be
Offset by more than 15c. It is therefore recommended that
TAT be used for extreme thermal testing only, and
temps regarded as unreliable.
Since all temperatures are referrenced to a standard Ambient (room temperature) of 22c, it is not possible to qualify your temperatures, unless you also provide your Ambient temperature.
I hope this answers your questions.
