Tcase is reported by the Q6600 sensor as well as the individual core
sensors.

I'm running overclocked to 3.2Ghz with the voltage at 1.4V.
The individual cores are typically 7C higher than Tc but also
read various values in between.

Tc is the value Intel uses to spec the temperature limits, etc.
See the following Intel document and have a look at the charts
on page 75 for the Q6600 G0 ( 95W ) chip.

First, that should be an offset of +15C....without it Speedfan will
read the Core temps 15C lower than actual. Sorry for the error.

Speedfan reports temperatures based on a particular sensor
reference point, as I understand it. It has been reported
on several overclocking sites that for the Q6600 ( and possibly
others ) the Speedfan data is incorrect unless one applies a
+15C adjustment. This can be done by going to the "Configure" tab,
"Advanced", select "Intel Core" from the drop down list and enter
a temperature offset of "15" for each core.

I'm using Speedfan version 4.33 BTW. As I mentioned earlier, the
adjusted temps corellate with Everest. Everest calls Tc "CPU" temp
while Speedfan reports it as "Temp2" on my motherboard. Speedfans
"Core" temp is the 8800GTS GPU temp.
