makotech222, to which temperatures are you referring; Tcase (CPU temp) or Tjunction (Core temp)? Please read the
Core 2 Quad and Duo Temperature Guide -
http://www.tomshardware.com/forum/221745-29-core-quad-temperature-guide
From the Guide:
Section 1: Introduction
Intel provides separate thermal specifications for
2 different sensor types; a CPU Case (not computer 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 CPU temp, and the
Digital
Thermal
Sensors measure
Tjunction (
Temperature
Junction), which is Core temp. Since these sensors measure
2 distinct thermal levels, there is a constant temperature difference between them, which is
Tcase to
Junction Delta. C2Q`s have
1 Tcase and
4 Junction sensors, while C2D`s have
1 Tcase and
2 Junction sensors.
Intel does not provide information comparing
Tcase and
Junction specifications. Consequently, there is much confusion among users regarding temperature monitoring, software utilities, test methods,
Calibrations and
Offsets, so
Results can be difficult to decipher and compare. 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

As you can see, it's important to be specific, otherwise the temperature topic is reduced to nothing more than apples and oranges thermal fruit salad.
randomizer, additional information from the Guide:
Section 15: Troubleshooting
Notice: A significant percentage of 45 nanometer processors are being reported with defective
DTS sensors, which can be characterized as displaying unresponsive Core temperatures, particularly at lower Scale. Also being reported are excessive
Offsets between Cores of as much as
8c. These issues apply to E8000, Q9000 and QX9000 series processors.
(

Offsets between Cores of up to
5c for Quad`s and
3c for Duo`s are normal.
