Quad core temps - is this normal?

[Mr Paul]

Remember there are two dies under the heat spreader, one die may have better contact with the IHS than the other hence the temp difference.

I suggest downloading realtemp and use the sensor test option, this will help you to determine if you have a stuck sensor.

Might be your Core0 temperature is stuck. Does it increase in line with the other cores if you run all cores at 100%?

Cores 1 & 3 always run 'hotter' than Cores 2 & 4 and yes all cores increase by similar increments when loaded.
