I get 65 with TAT, 50 Core Temp, playing Supreme Commander rarely goes above 30 with Core Temp
Thermal Flow
Heat originates within the cores, and is highest where the dual Tjunction sensors are located. Heat is then dissipated throughout the CPU die to the socket and motherboard, and to the Integrated Heat Spreader, where the single Tcase sensor, located between the cores, is 15c lower. Heat is then transferred to the CPU cooler, and finally to air inside the computer case. CPU temperatures are then determined by computer case cooling efficiency and Ambient temperature. Regardless of Load, Tjunction is always ~ 15c higher than Tcase, and Tcase is always higher than Ambient.
Parameters
(A) Vcore should not exceed ~ 1.5v.
(B) Tjunction is always ~ 15c higher than Tcase.
(C) Tcase is always higher than Ambient.
(D) Tcase Idle should be ~ 2 to 15c higher than Ambient.
(E) Tjunction Idle should be ~ 15 to 30c higher than Ambient.
(F) Tcase Load should not exceed ~ 55c.
(G) Tjunction Load should not exceed ~ 70c.
(H) Idle to Load Delta should not exceed ~ 25c.
(I) Tjunction Results are highest core Idle and Load.
Troubleshooting
(A) Vcore will typically sag ~ .025 volts under Load.
(B) Offsets between Core #0 and Core #1 of ~ 3c are normal.
(C) SpeedFan 4.32 can be configured to correct for Tcase and Tjunction offsets.
(D) Any hardware and / or software may misreport Tcase and / or Tjunction temps.
(E) 965 chipsets may misreport Tcase and Tjunction temperatures with +/-15c offsets.
(F) 6XX chipsets may misreport Tcase and / or Tjunction accuracy at upper or lower scale.
(G) TAT may not run on Vista. Orthos Priority 9 Small FFT’s simulates 88% load ~ 5c lower.
(H) Core Temp shows Tjunction 85c. This field is Intel's Tj max spec, is info only, and does not change.
(I) C2D’s manufactured with concave Integrated Heat Spreaders may report high Deltas and temps.
(J) An Improperly seated CPU cooler is the primary cause of abnormally high temperatures.
Offsets
If temperatures don’t meet the Parameters, then SpeedFan 4.32 can be configured to correct for Tcase and Tjunction offsets. From the “Readings” tab, click on the “Configure” button, then click on the “Advanced” tab. Next, click on the “Chip” field directly under the tabs, then use SpeedFan’s “Help and HOW-TO” icon included in the installation Program Group. Under “Contents” click on “How to configure” then click on “How to set Advanced Options”. Read this entire section including “Other interesting options” and “Temperature x offset. When configured, SpeedFan will provide a means to display all 3 Tcase and Tjunction temperatures correctly. SpeedFan is also extremely useful for observing temperatures and voltages using the “Charts” tab, while thermal benchmarking with TAT.
Some sources have said CoreTemp is right, and TAT is off by +15, and others say TAT is right and CoreTemp is off by -15. Confusion reigns! I've found that CoreTemp agrees with Speedfan and my bios mostly by a few degrees so I've tended to believe this. Ok even with 15 added, 45 under load isn't too bad, I don't think, and I'm on past 3Ghz.
I'm gettin' a real sense of deja vu!

Will bumping up Vcore reduce temps?
965 chipsets may misreport Tcase and Tjunction temperatures with +/-15c offsets.
T2 Tcase Idle (<35) 35
Tjun Idle (<50) 47
T2 Tcase Load (<55) 60
