I am sorry if this is the wrong place to post this.

I recently just built a system. Specs are these.

9900kf
gigabyte z390 aorus pro
corsair vengeance lpx (I think it's called lpx) @3000mhz
noctua nh-d15 cooler
corsair rmx 850w gold 80+ PSU

The only things I did in the bios was use xmp to put my ram to 3000mhz and I turned off multi core enhancements. I don't know much about overclocking and was hoping to just do things at stock for now. Everything else is at auto. My questions are these.

From the first boot up when installing windows updates etc. My chip was boosting to 5ghz on all cores, but while playing a little bit of Overwatch and some other games, my clocks were 4.7-4.8 and the voltages were fluctuating alot, I was using HWmonitor and Cpu-z to monitor stuff. The highest it peaked was 1.356 for a few seconds and then it would fluctuate between 0.720 at idle and would peak at 1.26something when I was gaming etc. I then decided to use HWinfo64 per recommendations from various forums I was reading.

Buildzoid says that VR VOUT is the reading I should be looking at and same can be said, again, from various forums. My VCORE reading in HWinfo64 says it peaked at 1.344 a few minutes ago, wasn't doing much but I guess something in the backround made it go that high for a few seconds. My VR VOUT peak is 1.264 and my VCORE on both HWmonitor and HWInfo show down clocking voltages to 0.720 and then they will fluctuate from 1.126, 1.179 and then to 1.212 or 1.244 etc... While my VR VOUT fluctuates between 1,150 at lowest to 1.264 at its highest but mostly 1.245 at highest. My temps are extremely fine, never going above 50 when gaming and while installing a bunch of things I hit 100% on a lot of cores for a few seconds, my chip peaked at 65 for maybe 3 seconds.

Are these voltages bad? Which one is the accurate one (meaning is buildzoid fully correct that I should only worry about the VR VOUT) Should I do something about them? A few friends I asked said that I should just not worry, go about my business and enjoy my new rig. But so many people on many different forums say that you should never leave stuff on auto, you should manually set things even for stock, voltages above 1.3 for stock are too high, talks of degradation etc... Everyone has a different opinion. I am very paranoid and want to make sure I treat this rig right so it can live a long and happy life.

Can someone please help me as to what I should do? Thank you.

Your voltages are absolutely fine and around normal limits which are confirmed by the fact that your temperatures are hovering around 50 during gaming.
Temperature spikes are perfectly normal too during gaming and yours at 65c is nothing to worry about at all.

If your voltages were too high then you would notice an immediate temperature increase which would far exceed the 50c during gaming with peaks of 65c that you are seeing now.

It is true that excessive voltage leads to chip degradation and that certainly is not happening in your case my friend.

Even though the high voltage spikes? I've read a bunch of places that these spikes are a very bad thing, idk what to believe :(
