I am new to cpu overclocking and got an i7 8700k to try and overclock it. I followed a guide with someone with an asus e370 extreme motherboard and I have an asus prime z370-a so for the most part I followed it. He did 1.3 volts for 4.8 and I was wondering if I do 4.7 on all cores and set the voltage to 1.25 is that safe? I did bench test and the temps were around 80c in 26.6 prime 95 and realbench. Temps are around 60-70c in games. I also maxed all the current and power limits in the bios as he did is that safe? I dont know why but I have an irrational fear of this type of overclocking possibly causing a fire in the pc.

Temps are perfect. You don't have to max out power and current limits as you are not doing any extreme overclock. Yet, no harm there since the current and power flow per cpu demand. You ll have to stress test the system for several hours using Prime95 or Aida or both, to claim stability. If the chip does fine 4.7 ghz with 1.25 V then there is some potential there to hit the silicon lottery. OCing is trial and error, every chip is different.
my i8700k runs at 4.8Ghz on all cores with 1.25V and a 200Mhz offset for AVX. I can pass pretty much all stress test (but I never did one longer than 2 hours). this is with an air cooler but it runs kinda hot (but only in stress tests). In gaming its absolutely fine.

Hi Clyde,
THe goal of overclocking is to find the lowest voltage for a given frequency.
The rule is, let everything on auto,
then stress test and note your voltage and frequency and put them manually in bios.
Then you have two path to follow :
1°/ Better performance :
Bump your multiplier until it's not stable then bump voltage (increments of 0.025-0.05V)
Once you've reach the frequencyyou want, lower the voltage as much as you can as long as it remains stable.
2°/ Better thermals
Keep stock frequency and reduce voltage as much as you can until it's not stable.
TIPS: Stay below 1.38V and 85°C during stress test for daily usage.
