Hello Serdal Aksun,
Your processor has a TCase value of 67.4°C; anything from the Tcase and below will be the expected temperature of the chip in normal use
When the processor is stressed out meaning that you are running heavy processor applications the temperature will go beyond the Tcase ( reach 80 to 85 degrees Celsius) and the processor will still be OK. The cooling fan is in charge to keep that temperature there.
If the processor temperature reaches 100 degrees Celsius or more it will send a signal to the motherboard to shut down to prevent mayor damages (overheating).
