Question Did I hurt my new rig ?

Hello there, first posting on this website so be nice please ^^

I just had some concern about my new pc. I brought a MSI infinite x11 a month ago, so let's say a beast. It was after having brought and refund two Lenovo legion t7 who gave me blue screens of death on top of each other a few days after turning them on. But that's another story.

I am really happy with it, and so far it was doing really fine. After the bad experiences I ahd with Lenovo, I took it easy and limited my use of this rig to two online games, quite old (world of warcraft and For Honor). I did use MSI center quite a lot to monitor use on load, but with my poor knowledge of PC's I am not sure that there was a problem before the recent events.

And here we go : like two days ago, when playing, I noticed that my gpu was between 80 to 100% use and my cpu hanging around 80C, with spikes to 90-92 which made my fans run VERY high and VERY loud, sound that made me realize there was a problem. This was on WOW. Then, I noticed my CPU temp was also reaching 80+, with spikes to 90+ that made the same effect, but without the GPU usage, on For Honor.

It happenned once and then, it was kind of stable at 70-80 C, with the same GPU usage, for the night. But today things got wild. I made a bit of testing and the problem was still there, with my CPU reaching 100 C on For Honor. Those are old games that shouldn't do any problem to high end pc's, but still it was killing my CPU. So after a bit of searching, it was the fps cap that caused all this. Or his non existence. After capping fps to +-60, everything went fine now. As far as I understand my cpu was trying to give way too much ressources on apps that didn't needed it. well, it was easy.

HOWEVER

I can't help but to wonder what happened. I dont't remember if the temp were running that high before, but if it did heard that kind of noise or the temp bar going red on msi center like this, I would certainly have noticed. But why would he suddenly go wild like this since I didn't put a fps cap before ? So my questions :

- Did I hurt my pc by letting him burn out the hardware like this for nothing ? That would explain why it didn't overheat at this point before, like, as it is a really good pc, maybe he just holded up until something got damaged, making him actually overheat ? Idk if it work like this though, but I just don't understand why he would start having problems without any specific action taken or installed programs.

- Why would he suddenly overheat for a fps cap problem if I did not have any problem before ? I mean, it was like overnight. on day it was fine, and then it started to got fiever.

- He didn't shut down nor close any game, and has never been in overclocking, so despite the heat problem, I can only assume that no thermal protection has been activated, and then no real damage have been done, right ? Or is it possible that by running at like 70-80 for a month, that would have dried the thermal past, what would have then made possible the spike to 100C ?
I didn't opened it to tcheck since on a one month pc, it seem very unlikely.

So mostly to know if those random overheating problems and a potential bad use for a month could have done damage to it. I am a bit paranoïed here but it would really be a pain in the ass if I damaged it by not knowing to recognize that there was a problem.
 
Oh and my config :

GPU : nvidia rtx 3080
cpu : I9 11900kf
32gb ram
Liquid cooling

and well, this kind of stuff. It's an msi so most parts are from msi themselves and it shouldn't have conflicts between hardwares aprt as far as I know
