Although Throttle temperature is 100°C (212°F) for the i7-7700K, it’s not advisable to run your CPU near its thermal limit. If your hottest Core is near its specified Tj Max Throttle temperature, then your CPU is already too hot.
The consensus among well informed and highly experienced system builders, reviewers and overclockers, is that cooler is better for ultimate stability, performance and longevity. Experts all agree that it's prudent to observe a reasonable thermal margin below Throttle temperature. So regardless of environmental conditions, hardware configurations, software workloads or any other variables ...
Core temperatures above 85°C are not recommended.
Core temperatures below 80°C are ideal.
Core temperatures increase and decrease with ambient temperature. The "standard" for normal ambient (room) temperature is 22°C or 72°F. For every degree you're above normal ambient, so are your Core temperatures.
• What is your ambient temperature?
Overclocking is always limited by two factors; voltage and temperature.
Excessive Vcore and Core temperature may result in accelerated "Electromigration" - https://www.google.com/?gws_rd=ssl#q=Electromigration
This prematurely erodes the traces and junctions within the processor's layers and nano-circuits, which will eventually result in blue-screen crashes that become increasingly frequent over time. Here's the maximum recommended Core voltage per Microarchitecture from 14 to 65 nanometers since 2006:
With high-end cooling you might reach the Vcore limit before
85°C. With low-end cooling you’ll reach
85°C before the Vcore limit. Regardless, whichever limit you reach first is where you should stop.
Remember to keep overclocking in perspective. For example, the difference between 4.5 GHz and 4.6 Ghz is less than 2.3%, which has no noticeable impact on overall system performance. It simply isn’t worth pushing your processor beyond recommended Core voltage and Core temperature limits just to squeeze out another 100 MHz.
