For that particular CPU the limit is ~66c:

Um, TCASE is not the same as the temperature reported by your CPU
What is Tcase vs. Tjunction?
These terms are related to processor temperature for desktop and mobile systems based on Intel® Processors. To allow optimal system operation and long-term reliability, the processor must not exceed the maximum case temperature specifications as defined by the applicable thermal profile.
Tcase is the temperature measurement using a thermocouple embedded in the center of the heat spreader. This initial measurement is done at the factory. Post-manufacturing, Tcase is calibrated by the BIOS, through a reading delivered by a diode between and below the cores.
Tjunction is synonymous with core temperatures, and calculated based on the output from the Digital Thermal Sensor (DTS) using the formula Tjunction = (Tjunction Max – DTS output).

You are reading TJunction, not TCase.
EDIT: For comparison, here's a Haswell part which lists its TJunction on Ark- it's 100C: http://ark.intel.com/products/76308/Intel-Core-i5-4300U-Processor-3M-Cache-up-to-2_90-GHz
