Optimal starting voltage for 9700k is around 12V, but adjust upward if instability occurs.

Spikes reaching 87°C are fine, it's when you hit a steady 85-90°C+ that you might want to ease things down a bit. To ensure your overclock is stable, consider running a stability test for several hours (a few hours), as just 15 minutes in Prime95 isn't sufficient. Tools like Linpack, Realbench, OCCT, Prime95 Blend/Large FFT are all good options. If you don’t encounter any errors after a few hours, you’re likely good to go. 1.35V should handle continuous use on Coffee Lake without issues. Great job on the overclock!
Yeah, I ran OCCT for around ten minutes and then used prime 95 for about 30-40 minutes. About ten minutes in, the temperature spiked into the 80s for a couple of minutes before dropping again. It seems like there’s a peak point during the test. The maximum temperature increased by a few degrees Celsius each cycle, so I might want to run it overnight. Do you think temperatures get too high if prime 95 turns off?
When your CPU reaches temperatures between 98-100°C, it begins reducing its performance. This situation is considered a failure because you don’t want thermal throttling during stress tests, and it could cause instability due to rapid changes in speed and voltage on Intel processors. If the temperature continues rising despite throttling (unlikely unless the cooler fails), the system will likely shut down.
