My fans are worryingly loud despite good performance?

Hello.

Recently, when I have been playing games such as Overwatch 2 or Civilization VI, I have noticed that the fans in the computer are abnormally loud, to such a level that it is worrying me. Most of the time they are just loud, but one time they even made a kind of scratching sound at which I got scared and turned off the computer. Normally, I would just assume it was an issue with dust gathering in the computer, but my performance is completely unaffected. The only game I have noticed unusually bad performance from Elden Ring, but I am quite certain that it is not related to this, since the fans do not get loud when I play that game. Could there be any issues with the computer's hardware that is causing this, or could it be the games software's fault?

hi

you should open and check if not done
if you have a high fan speed, in general it will be that dust has accumulated on the internal elements, and on the ventilation inlets / outlets of the case
if there is an abnormal noise, a fan could be faulty

Hi.

I did open the computer and I dusted it off, and unless the computer's hardware is very bad at keeping dust out and it is inside of the components somehow, there should be no dust. I am terrified to remove the parts and check them for dust, since that would most definitely void my warranty and then all my money will be gone for nothing. I genuinely believe that since I have done absolutely nothing that would harm the PC that it should not be sold with the risk of it breaking within the warranty time (the first year). Should I return it to my local reseller I bought it from and see what they think? I wanted to investigate the fan curve or fan settings in BIOS, but there is absolutely nothing configurable there, I could only see the current fan speed while in the settings tab.

you can try this, in order to check the temperatures and some fans speed

but yes, if you have big problems see the dealer
but if dust gets in, it's normal we can't completely prevent it
There are dust filter systems, but they must be cleaned regularly, otherwise the air no longer circulates
