Each Core can run in a different speed and consequently each Core has its own temperature. We need to focus in the overall temperature. Several games are not prepared to work with multiple Cores, so they just use 1 Core.
Now, I suggest you to make this last test before requesting a processor replacement through our contact center support.
Go to BIOS, make sure Processor Base Frequency is set to 3.5GHz and RAM is running at DDR3-1333/1600 1.5v or DDR3L-1333/1600 @ 1.35V.
Save BIOS changes, go to Windows and run our Intel® Processor Diagnostic Tool alone, close any other application. It is a stress tool.
