Coil whine sounds nothing like a fan/hair dryer. Here's an example and also explanation:
And here's another one:
I could find you ten more easily.
Now these are obviously very amplified, it's not that loud in reality, and of course you can also hear the fan and sometimes the disc drive in these videos. But that's unrelated, the coil whine is the very obvious buzzing sound that's separate from the fan noise.
What I mostly hear from my PS5 is the coil whine (which is pretty much constant when a game is running) and the disc drive (which is intermittent). The fan is usually rather quiet, the coil whine can usually be easily heard over it. And it's very easy to tell which is which, again, they're completely different noises.
Maybe some dumbasses put up fake videos, but this is a very real issue. I don't know why you're trying to debunk it.
Why the fuck would I pretend to have an issue like that? What's wrong with you?
