After asking several questions relating to my processor's temperature being abnormally high, I thought I found a definitive answer, using HWINFO. However on this application it shows two different temperatures, they are both 20C apart from one another. At the moment, I have Dark Souls 3 running in the background while I do tests. These are the different temps, could someone tell me which one would be correct?

CPU [#0] Asrock 970 Extreme3 R2.0
CPU 55.9C

And then CPU [#0] AMD-FX 8350 Black edition
CPU 35.9C

Hopefully the second one is correct, I highly doubt it but a man can hope. The system is dust-free as on earlier today. And has never once Blue-screened due to overheating.

Other specs
Ram- 16G
Video- Geforce GTX 970

AMD's temp sensors aren't quite as obvious as Intel's DTS sensors.

For one AMD"s idle temps are very inaccurate. Sometimes it's obvious (like below ambient) and sometimes they are just misleading. Also it's difficult to use a third party app and know what temp they are giving. It could either be the internal sensor, the package sensor or the socket sensor if the motherboard has one.

The best measure for AMD processors is to look at AMD OverDrive and look at the Thermal Margin. This works in reverse, because it is measuring the distance the temperature is from throttling. Again, idle temps are very inaccurate. You are more interested in your loaded temps anyway. So the larger the Thermal Margin the cooler you are.

Have a look...

By the logic that the article gives, my thermal margin is within 30-35C, and as such, I am 30-35C away from the max temperature. MY card is an FX model, and those chips are usually 60-65C max. So by the articles logic, I am at 25-35C while playing Darks Souls 3, hopefully this is correct, as I'm still relatively new to the entire idea. Thank you for the quick responses guys!:bounce:

I woudn't get too stuck on trying to tell what the temperature is actually. The real take away here is that you are that far away from throttling. AMD is very tight lipped about the throttle temperature. Their literature say that the max temp is 61C. However I seriously doubt the temp is that low for the internal temp sensor. It might be that low for package or socket temp. So without knowing for sure what temp the CPU throttles at, it makes it difficult to determine what temp you are at by extrapolating from the Thermal Margin. I seriously doubt you are 25 - 35C while running DS3. I don't know how much of a load is placed on your CPU running DS3, but I would suspect that your idle temps are 25 - 35C, not your loaded temps.

So rather than getting hung up on what your absolute temps are, just know that you are a good 30C away from throttling. Whether the actual temp is 50C or 45C, it doesn't matter. It means you have some thermal headroom and you aren't close to that unknown limit.
