vanniko63,

Core temperatures are measured at the heat sources near the transistor "Junctions" inside each of the Cores where temperatures are highest. "Tj Max" (Temperature Junction Maximum) is Intel's Thermal Specification that defines the Core temperature limit at which the processor will "Throttle" (reduce Core speed) to protect against thermal damage.

Although most Intel processors reach Tj Max or Throttle temperature at 100°C (212°F), it’s not advisable to run your CPU near the thermal limit, so Core temperatures above 85°C aren't recommended.

Here's the operating range for Core temperature:

ccampy,

Respectfully, you are misinformed. With few exceptions, Throttle temperature for most Intel Core i processors is 100°C.

Examples:

Core

7th Generation 14 nanometer i7 7700K / i5 7600K (TDP 91W / Idle 2W),
6th Generation 14 nanometer i7 6700K / i5 6600K (TDP 91W / Idle 2W):
Tj Max (Throttle temperature) = 100°C

5th Generation 14 nanometer i7 5775C / i5 5675C (TDP 65W / Idle 2W):
Tj Max (Throttle temperature) = 96°C

4th Generation 22 nanometer i7 4790K / i5 4690K (TDP 88W / Idle 2W),
4th Generation 22 nanometer i7 4770K / i5 4670K (TDP 84W / Idle 2W):
Tj Max (Throttle temperature) = 100°C

Legacy Core

3rd Generation 22 nanometer i7 3770K / i5 3570K (TDP 77W / Idle 4W):
Tj Max (Throttle temperature) = 105°C

2nd Generation 32 nanometer i7 2600K / i5 2500K (TDP 95W / Idle 8W):
Tj Max (Throttle temperature) = 98°C

1st Generation 45 nanometer i7 860 / i5 750 (TDP 95W / Idle 12W),
1st Generation 45 nanometer i7 920 D0 (TDP 130W / Idle 12W):
Tj Max (Throttle temperature) = 100°C

Core 2 45 nanometer Q9550 E0 (TDP 95W / Idle 16W),
Core 2 65 nanometer Q6600 G0 (TDP 95W / Idle 24W):
Tj Max (Throttle temperature) = 100°C
