Speedfan can read 3200 core temp?

post #1 of 3
Thread Starter 
Hey guys,

I just updated my BIOS to the latest and installed speedfan. I have a new temp reading. It's called Core. When I go to configure it has the sensor chip listed as K8? Is this my true core temp? The one called CPU is ALWAYS out by a long shot. Should I take this new one as the true core temp? It fluxuates when I run Prime.

Yeah, in the new version of speedfan (4.29) there is a reading for the 'core' temperature. The 'CPU' temperature is the reading from the mobo socket, while the core temp is read from a diode inside the K8 CPU, near the hottest part of the die.

At first I too disregarded this new temperature, but after a bit of watching I am now sure this is the core temp. It is much more responsive to load changes then the 'CPU' reading, and is usually a little higher in its reading.

Try for yourself, go to the 'charts' tab and view both 'CPU' and 'core' temps. From your idle temperature run Prime95 and watch the core temp shoot up, it will shortly level off with the 'CPU' temp levelling off one or two degrees lower.

In this image of speedfan the core temperature is represented by red, and the CPU temp by green.
