I actually mentioned that I indeed know that in the first post

I know intel shows different temps for each core and they can be different etc

Retention can be a difficult task for some

Pretty sure most everybody is experiencing a 10ish degree difference between core 0 and the other cores with Sandy Bridge. I'm happy that you question that it's pretty unreasonable... because it's true, that's a ridiculous temperature gradient.

Eh mine is usually 7-8C on the hottest to the lowest core.

I've reapplied the past several times. Don't know what the deal is.

Yea, it's nothing new
I'm just trying to use this data to calculate the actual die temperature based on probability instead of just averaging out 4 cores. I'm bad at math that's why I'm asking you guys.

I mean, if the two hottest cores are coincidentally the 2 cores that have the most similar temperature, those two cores have something in common. One core is abnormally low temp which has a 200% higher chance of being an incorrect sensor than the two hottest cores which agree with each other the most. The 4th variable is the last core which is actually closer in temp to the second hottest core then the coolest core. Am I wrong in static that the logical calculation would be a simple average between the 3 hottest cores (the cores closest in temperature) in this scenario? Again, I'm bad at math, feel free to school me.

Again, the temps are:

CORE0: 63c
CORE1: 72c
CORE2: 75c
CORE3: 68c

Its usually due to the way the Heatspreader was applied at Intel, its pretty common. Of course Turbo on one core will always exaggerate the temp difference.

Solution.... reflow the solder.

Flip the CPU upside down and apply a blowtorch to heat up the TIM between die and IHS. It's been done before but very risky for obvious reasons.
Once again...
