CPU socket or core temps.

post #1 of 10
Thread Starter 
Hi guys im a bit on which temp i should be watching when stress testing my rig.

Should it be the cpu socket or core temp?

My current temps under load are:

CPU socket - 46c
Mainboard - 30c
Cores - 50c

All monitoring is done using CPUID HM pro.

CPU temp is more important than the cores but I do keep an eye on my core temps as well.

No, CPU temp is measured at the socket and can be changed by pointing a fan at the back of the motherboard socket. Core temp is the temperature read from a diode on the CPU.

Pay attention to Core temp!

Pay attention to Core temp!

You should use core temps unless they are lower than your CPU temp. If you core temps are lower, the CPU almost definitely has bad sensors.

I use core temps, I find them to be the telling story between stability or not, and when I've hit the heat wall.

CPU temps can also be used with a pretty good amount of accuracy and I keep an eye on them also. Some people make the argument that CPU temperatures are more accurate than core temps but each to their own, I guess.

Ok so what is the mainboard temp. Should I worry about that.

No, you shouldn't have to worry about mainboard temperatures, I believe they have to do with the motherboard and should be just fine.

If you CPU temps are higher than your Core temp you're either liquid cooling, have a high end air cooler or your case has poor airflow around the socket.

My loaded core temp is 45*C with the typical 11*C addition for Thuban CPUs while my CPU (socket) temp gets to 57*C under the same load. Before I went liquid I had a Megahalems on this same chip at the same clocks that had a loaded core temp of 61*C and CPU/socket temp of 55*C. The additional 2*C to the CPU temp is because there isn't two 120x38 fans blasting air over the socket anymore.

Pay attention to core temp with Phenom II X2, X3 and X4 CPUs and make good judgement when adding to core temp reading for Phenom II X6 CPUs to get a close to accurate reading.

Temp sensors are not that inaccurate on non X6 Phenom II chips, follow core temp.

Mainboard temps are measured in a different spot on different motherboards.

Mainboard temp don't matter much unless you're running fanless or you have very poor airflow. Mine only varies 2-3*C loaded to idle.

yay double post.
