Difference in temps showed by core temp and ASrockAXtu

Postby _ThEcRoW » Sat Jul 20, 2013 3:07 pm

Hello, just discovered the core temp app, and liked the widget on the desktop, but i noticed that while the asrock utility is showing 37c, the core temp plugin is showing 21-23c. Why that difference?. On what temp i should be trust more for safety. I'm using an amd fx 8320.
Thanks in advance!!!!

This is explained in the FAQ. Most of the time, on AMD CPUs Core Temp reports temperatures which around about 15C below the real value.
So you can go to Options --> Adjust offsets and set a 15C offset to match what the ASrock application is showing.

The two temps that you are seeing are from different points. The Core Temp software measures what is perceived as the CPU core temps, as it's name suggest. Asrock and other software typically reads the mobo thermister located below the CPU socket. The CPU SOCKET temp (which is typically reported just as "CPU temp"), runs anywhere from 10-25C higher temps because the socket has no cooling like the CPU has.

According to AMD engineering you do not want to add to the temps that Core Temp shows as this will show significantly incorrect temps. The core temp readings on AMD CPUs/APUs from Phenom models onward use a unique process to generate the true "core temp". Core Temp, OCCT, AMD Overdrive and HWiNFO software does provide relatively close to correct temps when the "core temps" readout is in the range of 40C-70C. Below 40C the temps tend to drift and be far less accurate, sometimes even showing negative temps at idle. These temps are of no concern however as the max 24/7 temp is all that matters. On most AMD desktop CPUs/APUs the max 24/7 temp is in the 61C-70C range. Laptop CPUs/APUs tend to run at higher temps (by design), up to 90C without issue. You can generally find the max 24/7 temps for each AMD desktop model on their website.
