Difference in temps showed by core temp and ASrockAXtu

Post by _ThEcRoW »

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.
Main rig:
AMD Ryzen 9 5950X (True Spirit 140 Direct) / Mobo: Asrock Fatal1ty X470 / EVO 970 500GB + WD Blue 250GB + HDD / GPU: Dell RX 570 4GB / Mem: 2x16GB DDR4-3200 G.Skill 32GTZKW TridentZ - 32GB total / PSU: Seasonic Prime Ultra Gold 650W
NAS:
Core i7 2600K 3.4GHz @ 4.3GHz (Scythe Mugen2) / Mobo: Biostar TP67XE / 2x Inland Pro 120GB + HDDs / GPU: ATi Mach64 VT2 / Mem: 4x4GB DDR3-1600 G.Skill 8GBXL RipJawsX - 16GB total / PSU: Seasonic S12II 620W.
Secondary rigs:
Core i3 7130U / MiniPC / SanDisk SDSSDP-128G / GPU: Intel HD 620 / Mem: 1x8GB DDR3L-1600
Xeon X3430 2.40GHz @ 3.06GHz or Core i3 540 3.06GHz @ 4.0GHz (Freezer 7 Pro) / Mobo: MSI H55M-ED55 / PNY CS1111 240GB / GPU: ATI FirePro V3800 / Mem: 4x2GB DDR3-1600 G.Skill 4GBRL RipJaws - 8GB total / PSU: Seasonic S12II 620W
AMD Phenom II X4 B93 / Mobo: ASUS M2A-VM / GPU: ATI Radeon Xpress X1250 / Crucial M4 120GB / Mem: 2x2GB DDR2-800 - 4GB total / PSU: Antec 380W.

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.
