I was a firm believer that Unclewebb was on the right track with Real Temp but it appears he may have been off by 5°C.
It seems there is now some "official" word from Intel
The latest version of Core Temp (D/load Core Temp 0.99.3
) has some interesting information in the change log
Temperature Utility Comparison
•Intel®Core™2 Duo processor
•TJ should be 100°C
I find it ironic that the Intel document "splits the difference" between Core Temp and Real Temp, so by the looks of it you can add 5°C to all your overclock temperatures if you were using 95°C in Real Temp and Core Temp previously.
