Last week I got my first gaming laptop, an MSI Delta 15, and had to return it because of a broken part. When I got the replacement set up, it had a weird fan noise that the first one didn't have. If it wasn't for the first one sounding completely normal I would've just chalked it up to how the laptop is supposed to sound. I attached a link to a video for how it sounds. Is it just dust in the fan or is there a legit problem with it? I really don't want to replace the laptop a second time, so any advice would be great.
