”As an overclocking enabled Core series processor, the i7 7700K does indeed have some overclocking chops. A baseline 4.2GHz clock speed is pretty solid for the average person, but running at close to 5GHz is really stellar. The last processor I had that came anywhere close with reasonable voltages applied was a 2600K. Now, getting anywhere close over the past few generations of Intel processors was fraught with temperatures that could not be contained with anything less than a full-on water cooling system under load when you started cranking on the voltage. I was surprised, pleasantly at this point, that even running at 5GHz was possible with an AIO cooling solution. I was able to keep this processor at 4950MHz under a Prime95 load for hours without hitting temperatures that would throttle the processor speed. By using 1.36v applied in the BIOS, and tuning the rest of the voltage manually, the maximum temperature I hit was 94 °C with an AIO. Now, you can always tune for higher speeds by using the AVX offset in the BIOS, but I am happy with where this chip went. The performance and overclocking capabilities of Kaby Lake are a refreshing change of pace from the hot running chips of previous generations.”
