i5 750 - Processor temp & difference between Tjmax and Tcase

Hi all,

just a question regarding the CPU temperature for the i5 750.

I am running it with the Intel boxed stock fan on an Asus P7P55D Mainboard since end of last year without any probs.

Yesterday I started the Asus Probe tool to check the CPU temp - it aboout 42-244 C on Idle on 55-60 when starting

I started prime95 to do a stress test, and after 20-30 seconds the CPU temp was at 70 C - so I stopped the stress test.

I checked http://ark.intel.com/Product.aspx?id=42915&processor=i5-750&spec-codes=SLBLC this page and saw the line : TCASE 72.7°C

When runnign different tools to check the CPU temp there are alo references to Tjmax that refer to a maximum of 99C.

Can anyone explain me the differnece between these values in his own words? I am also not sure if the Asus tool is checking the Tjmax or the Tcase temp.

And of course I am a bit concerned if the stress test I have done could have caused any harm to the CPU due to high temperatures (even if the 70 C temp was only for 2-3 seconds)
