Wow, great guide man! Man we just need voltage guides. More like explaining the max limits and what it does etc.

That's correct.

Thank you.

I'll definitely be working on a voltage guide soon.

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.
Best regards,
Francine
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. yessir.gif

Looks like Francine can't make up her/his mind:

There are so many applications for processor temperature monitor and may not be accurate. We recommend Core Temp software to monitor the temperature of your cores. Its a free utility online. If your core's are running at 61.6 or 62 C, then they are running hot and you may have a defective processor.

Very nice guide. There have been so much confusion about these temps.
Voltage guide would be great.

Yup she is probably just an employee who will write what they are told to write, but instead she doesn't even seem to know what she's talking about. -1 for AMD customer care.

But probably the most logical and proper explanation is indeed from Alex Cromwell. And after my testing, it does look correct that Core Temp is the one to watch.

Oh and forgot to say thanks to you ALUCARDVPR because after reading some threads, there were a few people who kept arguing with you trying to discredit your information and simply refuse to believe it!

Your welcome. Yeah in the end those guys were just trolls. Pretty sure they were just arguing to argue with no real valid points or proof to back up their theories or statements. Thanks again for thinking logical and actually putting it to the test.

After reading this thread I put two 90MM fans on adjacent sides of my motherboard so that ~25% to ~30% of the fan air was going underneath the board on my test bench. This also helped me in bringing down my cpu/motherbaord temps as well while the "core" readings remained the same.

Even though it is reading ~10 C. higher... I like to try and keep my cpu/motherboard sensor daily load temps to below ~60/61 C. However when stressing "short term" tests with Prime/LinX they have sometimes gone into the mid 60's C. Moving ahead I've decided now to try and limit that particular sensor reading to a maximum peak temp of ~70 C. or less.

Edit: I've been running my FX8150 @ 4.6GHz 8-cores 100% load "crunching" WCG and the 2 fans running air underneath the motherboard have brought down the temp difference between cpu core and cpu/motherboard to ~3/4 C. (45 C. core vs 48/49 C. cpu)

Excellent idea.

I did forget to note that perhaps socket temps might have a max thermal value separate from Core temps as well but of course that will range from mobo to mobo.
