Hello.

First of all my native language is not english, but i'll try to explain my problem. Recently i bought desktop PC. Problem is- amd overdrive shows me that cpu temp is 50-70°C. And hwmonitor showed 116°C after playing CoD BO2. BIOS shows 54°C and AIDA64 shows 13°C as minimum and using system stability test it showed 30-40°C after 5 minute test. So who to trust? is it possible that my cpu on idle is 13°C with stock fan?

Motherboard Name: Gigabyte GA-F2A88XM-HD3

Now im doing stress test by using prime95. hwmonitor shows 88°C and aida64 shows 53°C

I added print screen from hwmonitor, amd overdrive and AIDA64.
Now amd OD shows only 30°c during stress...

Ah! The dreaded APU issue.

On my A10-5800K, I had no less than 4 different sets of heat readings to decipher to figure out what was what. Currently, to me, AIDA64 seems to be the correct one, because at least it is showing two sets of CPU Core temperatures. (When you are letting your CPU idle, are they less-than-ambient?) Depending on your cooling solution would be which set I would believe...

Try CoreTemp, and cross-reference, just to round things out. Frankly, I am a bit surprised that AMD overdrive doesn't seem to be displaying things quite right - that is a bit too low for a prime95 stress test. But, nothing is perfect.

My room ambient temp. is higher than 13 celsius :D but thats what aida64 isshowing me when idle. And 'bout coretemp- i cant even run it. Amd overdrive is most inaccurate for me, cuz' when, idle it shows me 60° and when on stress- 30° . I read that bios is using 100% of cpu and thats why it is showing me 50°... if it os true, then i have nottin' to worry about. :)

Yeah, I'd say you're definitely in the safe zone.

The real issue is which is the Core Temperature, and which is the Socket temperature. I think the ~40 degrees is your core, and the ~50 is your socket.

Core temperatures are obtained by a weird method; the reading is fed through a type of weighted equation which provides very accurate results for when the CPU is at load, but when at idle they readings are very weird - usually around ambient or below.
