Disable AUX - it means nothing
Enable PECI in your BIOS to get a correct reading from the mobo. PECI sends the data from the Digital sensor DTS on the cpu - the one used with TJunction.
Here's how C2D temps work. The DTS on each core is recorded as x many degress away from the junction point (can be 85C or 100C). Coretemps/speedfan etc use this formula to calc the temp; With a junction of 85 and a TJunction reading of 50, the coretemp is 35C
Temp measurement is not exact and is affected by how the mobo reads the DTS data
