3900x fixed voltage 1.2v dangerous?

Hello there I got myself new pc pieces including a 3900x with a asus tuf x570 - cooler dark rock 4

I mainly use the computer when I come from work ( using 3dsmax for rendering and a bit of gaming as well )

But I noticed that while stressing out at cinebench r20 temps would rocket to 86º. (stock score 7400 - with the changes into voltage and speed - 7100 score )

I went to ryzen master and set a peak voltage to 1.2 at 4050mhz and it seems to stable out while under stress gets to 75º and idle 40-45º. ( with stock it would sometimes touch on 65º-70º on idle, would seem unstable somehow? )

BIOS chipset, graphics card everything up to date, windows 10 aswell, was the first thing I did after start moving stuff.

My question is the peak and average voltage is at 1.2 always, is there any way on ryzen master or anywhere else that i can set the voltage to not stay static? ( if it's not dangerous I would leave it that way? )

Bios settings on auto or they shouldn't be?
If you require any more info would gladly provide!

Sorry I am no expert into this matter and would like some input into this, thanks alot guys!

Re: 3900x fixed voltage 1.2v dangerous?

1.2V vCore is not dangerous - yet usually it should jump around from 1.1-1.5V
but as you said it is 1.2V all the time you have to check if you read vSOC - and 1.2V vSOC is VERY high

PC: R7 2700X @PBO + RX 580 4G (1500MHz/2000MHz CL16) + 32G DDR4-3200CL14 + 144hz 1ms FS P + 75hz 1ms FS
Laptop: R5 2500U @30W + RX 560X (1400MHz/1500MHz) + 16G DDR4-2400CL16 + 120Hz 3ms FS
