In case anyone was wondering how widespread coilwhine is, I have quite a bit of experience with it myself, 5 different PlayStations I've owned (I've owned a total of 6, I didn't include the Nidec fan PS5 I owned for equal comparison of coil whine).
My brother also has a PS5 and he got super lucky, as his unit is the quietest PS5 I've heard.
There's been a lot of issues with the PS5 and I'd like to elaborate on some of these issues.
1. The fan bearings. Yes I would even put this above coil whine. Most people complaining about coilwhine, it's not that loud y'all. The fan bearing can noticeably ruin the sound of your console during all scenarios though. I've had 4 PS5s with the NMB fan, 1 with a Nidec, and 1 with a Delta. Of all the NMB fans 3 of them had bad bearings (making either a noticeable squeal or squeaking sound) and it only gets worse when it spins faster. 1 of them (my current console) was perfect and had no squeaking, squeal or grumbling. I can't believe how bad some of those fans sounded and they were all manufactured by the same damn company.
2. The design of the plates on the side of the console. They are just too many random issues they cause. Some of them vibrate and cause buzzing sounds of their own (different from coil whine) and it just ends up feeling cheap and tacky.
3. Coilwhine (of course). This is an issue but from all of the consoles I've owned, they don't actually range that much. The average console measured at 36-38 decibels. My brother's PS5 (the quietest I've ever seen even on all of youtube or any medium) measured at a whipping 35 decibels. It's not the sound that's the issue, really it's the CHANGING OF THE PITCH that's so annoying. If it was a constant hum at 38 decibels no one would complain, but because of the pitch that's always changing it can really bug some people. The only thing Sony needed to do was splat on some anti vibration silicone and call it a day, that would have resolved 99% of these issues with the coil whine. They could have gone with a higher volt capcitor too, but I don't think that matters as much as the silicone (same type of capacitors are in the Series X, the goo makes all the difference).
4. The glossy black. After the PS3 and PS4 you'd think Sony would have learned their lesson and just make the fuckin thing matte, but no they had to make it glossy and a dust magnet. This urks the shit out of me.
