Tcase vs. Tjunction?

[bavman]

Why do some cpu's on intels site have a tcase and other have a tjunction listed? Whats the difference between the two?

So a chip like the su4100 with a Tcase of 100*c or the su7300 with tjunction of 105*c can safely operate at 95*c?

Apparently, but I wouldn't fancy running it 24/7 at that heat.

Apparently also the cpu temps that we monitor are higher than the actual Tcase temps so if we stay within Tcase temps we will actually be lower.
