[SOLVED] CPU unnecessarily hot for overclocking?

[visconic]

With my specs (and according to things i've seen online), I should be able to OC my CPU to 5 GHz, or at least 4.8-4.9. I started at 4.7 GHz and increased the voltage on the CPU until it stopped crashing when I run Prime95. This voltage is about 1.3V. When I run Prime95 at this voltage, my cores average about 80-82C, which (according to the guide i'm using) is too hot to increase voltage further. When idle these cores are a tad under 40C. I had LLC on auto during this process. Is this a normal temperature to have @ 4.7 GHz 1.3V for my processor + case + cooler? Is there some problem with my components that's ruining my temperature? Not great with computers so any help is much appreciated

i used the youtube video to overclock my 8700k to 5Ghz at 1.26 max temps on prime95 are 72-74, but im using a 360AIO

most 8700k can hit 5Ghz but you may be unlucky,

You aren't going to do much with a hyper212 on an 8700k.

Prime95 small fft with AVX tech disabled is for temps. For stability use Asus RealBench.

LLC should be no more than 50-70% if setting manually.

You think you can overclock an 6 core processor with a cooler designed for 4 cores?
It should run a stock 8700k and probably allow a little OC, not not 5GHz.
