Overclocking Issues

[adamch10]

i recently bought a new pc and i wanted to overclock it. (specs):

CPU: i7-8700k

Mobo: ASUS ROG STRIX z370 - F  gaming

RAM: Hyperx fury DDR4 8GB (i'm planning to get more but the prices right now are horrendous :/)

PSU: Corsair RM850x

Cooler: Noctua NH-D14

 

Here's the issue: I get absurd temps on my CPU. when running small FFS on Prime95 it instantly reaches 100 degrees and throttles down. Is that normal? i'm pretty sure i mounted the cooler correctly, i get around 30 degrees on idle and about 60 while running Blend (Prime95). When i tried overclocking i couldn't get a stable 5.0 GHZ even when i set the voltage to 1.420V. Also i noticed that in CPU-Z  and in BIOS/UEFI the CPU didn't get the voltage i actually set, but  around 0.02V lower. when running Cinnebench the voltage lowered even further, to as far as 1.28 (from 1.40 while i set 1.42 in BIOS) Is all of that normal and i just came last in the sillicon lottery or is something wrong with my CPU? (or i'm just doing something wrong?)

I got the same issues with my 8700k. Runs fine on stock (30c idle and 60-65 in pubg) when I tried to oc it to 5.0ghz it instantly reached 100c and I got a blue screen. 

 

Would like to see an answer

If you want to run 5.0GHz with decent temps and a modest cooler, you need to delid your CPU.

Well i got a 240 liquid cooler. So I think it should be possible without a delid, or at least 4.9
