Here you go, exactly as I thought. Eazy tune 6 measures the cpu temp, which is around 10Â°C higher than the core temp. When using 2 cores, the core temp has a reading. When using 4 cores, there is no core reading.
I tried various voltages and speeds to see if the temp was consistant and in my case it was. Under load, cpu temp was 10-11Â°C higer than the core temp. The core temp was the temp we usually consider when we mention our temp. I found that it was usually 11Â°C higher but at times it would drop to 10Â°C, Never was it less than 10Â°C difference, while under load.
However, I don't know if the same difference still applies when using 4 cores. The best way to figure this out would be to ask someone with a 955be or 940be to show a comparison. I still don't know how accurate it would be, but it'd give me an idea if the cpu temp is still 10Â°C higher than core.
