Hello all, new here to overclock.net but was mostly browsing as a guest. Anyway I wanted to share some interesting information. I basically had a quest to find out what is going on with the CPU temp vs Core temp theories. So I e-mailed AMD, got their response and quite frankly I was not satisfied. Here is the response:
"Thank you for contacting AMD. The maximum temperature listed for our processors refers to the overall CPU Temp. So, the best application to monitor your processor temperature is from your motherboard manufacture. Dependant on your motherboard manufacture, the manufacture company will have a processor monitor application that you can dowload and use to monitor the temperature of your CPU. Lastly, the best processor temperature reading is Core Temp.
In order to update this service request, please respond, leaving the service request reference intact.
AMD Global Customer Care"
Now that didn't really answer my question which originally was "Which temperature is important to monitor, CPU temp or Core temp?"
Now based on ALUCARDVPR's previous information, AMD suggests Core Temp is what we should monitor.
On my FX-8120 I was getting 54C on CPU temp and 33C on Core Temps on STOCK SETTINGS NO OC. I have a Corsair H80 cooler. This made no sense to me that with this cooler I was getting up to 54C on load. Ambient temperature is 20C in my room as well. So this made me realize that Core Temps is probably more accurate.
But to further strengthen the argument that CPU temp is actually just a Socket Temp BELOW the socket, I opened up my case and put a nice cold fan right behind the Mobo. Low and behold, Core Temps at load remained the same while Socket temp reduce by about 7C.
So this brings me to the conclusion that it probably is more accurate to monitor Core Temp seeing as how the top of the CPU is what's actually attached to the cooler while below the socket will theoretically run hotter.
Hope this helps the rest of you on the quest for maximum overclocks while maintaining safe temps. Edited by symmetrical - 10/26/11 at 8:42am
