Hello TechPowerUp people of wisdom
I just built a system with an E8400 E0 CPU
I downloaded HWmonitor.exe to monitor CPU temperatures, as I like it's appearance best. However, I noticed it reports a single value for CPU temp from the chipset, which corresponds to the "CPU temp" reported by the monitor in EZ-Tune that came with my Gigabyte mobo, and it also reports seperate, higher values for CPU core temps This puzzled me, so I ran Core Temp too, and that reported lower core temps
So I googled and found several explanations about this sort of thing, best of which seems to be this article http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3251&p=4
What it seems to be saying is that you can't necessarily rely on core temp reading from any monitoring util, but some may be better than others depending on how well they've judged/guessed the Tjunction reference value for the particular chip and stepping - eg: one util may be better for E8400 C0, but another may be more accurate for E8400 E0.
Now, when I get my system bedded in and start trying to OC it, the perceived wisdom seems to be that I should aim to keep my core temps below 60C, but according to what? So, which util should I measure core temps with on this particular CPU and stepping? Which is best? What temps are others running OCed E8400 E0 at, and what are you using to measure those core temp values?
thanx in advance, Pum
