The processor temperatures are measured not by core but by its overall temperature which is the one to indicate eventually, if the processor presents over heating issues. The different cores might have different temperatures and it is expected to see a 15°C-20°C difference between them since the temperature depends on the load being placed onto the processor. Please keep in mind the services running within the Operating system’s background always use processor resources; therefore, even on idle, the processor is being used.
Still, for troubleshooting purposes you can:
Run the Intel® Processor Identification Utility; make sure the processor is being properly recognized: http://www.intel.com/p/en_US/support/highlights/processors/toolspiu
Also, you can verify its functionality by running the Intel® Processor Diagnostic Tool: http://www.intel.com/support/processors/sb/CS-031726.htm
If the processor is not being properly recognized or not properly working, please make sure you have the latest BIOS version of the motherboard in use in order to have loaded the latest micro code available for your processor.

I have a problem.
The processor: i3-2100 Motherboard: ASRock H61 U3S3.
The two core CPU temperature is always 8-11 degrees difference.
Idle: 28/38 degrees. Load: 47/58 degrees.
Why is this?
There are two cooling: Intel original, and an Arctic Freezer 7 Pro Rev. 2.
Everything is in place, pasting, fitting is all right.
Both are doing the same thing. Measuring the same three programs.
Is there a solution?
The CPU temperature sensor or bad?
Please respond to that trouble or not!
