maximum safe? most will agree you shouldn't go past 1.40v on the core unless you have delid with liquid metal and very good cooling. your dark rock 3 isn't enough on the cooling end, and your msi carbon pro is going to run into vrm/mosfet heat issues as well.
1. Maximum safe was not my question. My question was with what core voltages a 8700k @stock operates in and what is considered "normal" stock. I mostly asked out of curiosity.
2. Why wouldn't be the Dark Rock Pro 3 enough on the cooling end? with an Corsair H110i you can cool maybe ~5 degress celsius more, but than the case sounds like a boing 747 at takeoff. Maybe with custom loops you can be much cooler but I don't plan to break overclocking world records. my Dark Rock Pro 3 runs plenty cool at 4.8 GHz (will stay under 85C with prime95 running with AVX). Yes, if I go to 5 Ghz I have to set an AVX offset (hey, but even they guys from silicon lottery do that!)
if you are asking stock with pirme95 load you might see anywhere from 1.15v to 1.20v depending on the cpu lottery. though most are going to end up in a tight range, there are probably a few processors that can run outside that range depending on the silicon.
otherwise its normal vcore stepping range was determined by a bunch of factors at the factory, each cpu will be different. dont interpret that as meaning if the cpu1 runs at a lower stock vcore than cpu2 then cpu1 must overclock better... there are more factors than that. generally intel saves the cpus that end up with the lowest vcore for laptop and xeon so they can further undervolt and underclock to get tdp/wattage down or for higher demand stability reasons.
your dark rock 3 is an excellent air cooler, i didnt mean to say it wasn't. i was just mentioning it really isn't up to the task of going over the max safe vcore. since you posted in the overclocking sub and i wasn't exactly sure what you were asking put "maximum safe" with a question mark. and 4.8ghz is plenty of cpu horsepower... 5.0ghz will really only get you about 4% more performance which is pretty much negligible in most tasks, especially gaming. though you can likely tinker a little bit with llc and avx offset and get a little higher while either maintaining the same temps or possibly a tiny bit lower, but it will take some time and overclocking patience.
