The part only becomes extremely loud after a short use, even though I only watch Twitch or Youtube. Do you have any tips how I can reduce the whole thing? Don't want to take the part apart.
If you don't already, you should use Safari. Far more resource-friendly.
You should place the MacBook on a different surface. It seems like the vents have been blocked off somehow. Also watch the videos on YuTube that show you how to clean your MacBook.
