Thanks for joining the Processor community.
I am trying to understand the context around your question.
At this stage, are you reading this information from online magazines, forums, or any other technical documentation? Would you able to provide links?
What I posted above was from a discussion I had years ago on
an ASUS support forum.
The technical info was gleamed from Intel® Core™ i7 Processor Series Datasheet, Vol. 1
What I'm getting after is when cooling the CPU what represents
the best temp indicator for cooling effectiveness? Should I be concerned the
most with CPU temp or core temps? I understand in 4th gen processors. The core
temps come from the DTS. The DTS does not output the real core temps but how
close each core is to TJmax. The DTS is
for thermal protection not absolute temperature. CPU temp is reported by an analog
sensor at the center of the chip. To evaluate effectiveness of processor
cooling be it air, liquid or other, which is the best indicator. From my
understanding TJmax is not a fixed number but can vary for core to core. Also the CPU temp reported by the analog
sensor is outputted to the BIOS. The BIOS interprets this signal and by using
tables to determine the CPU temp. These tables can be inaccurate. Core temps
outputted to 3rd party software like Realtemp or Coretemp are
reporting the core temps ## degrees Celsius. Are the core temps reported by 3rd
party software of any value?
Do I give you enough info to see what I’m after? If I run
Intel processor diagnostic tool the only tem it reports is in the output log
file. When I ran it today it says my cpu temp is 62 degrees Celsius from max. I
assume this is from TJmax?
Thank you for your help in understanding what is of value.
Thanks for the information. I will come back as soon as I get any feedback from our engineering team.
Allan could you edit the subject line of the post to CPU temp vs core temp? never mind I got it edited.
Any updated info on this post?
Andy, the information you are presenting is still accurate.
Thank you Joe!
So the best source to evaluate cooling effectiveness or efficiency is the CPU temperature?
