My 17 Pro Max is making what sounds like hard drive noises when plugged into the charger and it varies based on if you’re using the phone or letting it idle. It doesn’t matter what charger or method I use it has been repetitive still. I reported this to Apple about a week ago now and they haven’t been able to acknowledge anything other than they have replicated it but have no recourse. Occurs even after restarts of the phone. Can’t upload an audio clip apparently so I’ll try to find another way.
