That's interesting, thanks. I remember watching some Youtube video made by a repair shop where they tried to fix the coil whine per a customer's request. They tried applying some "liquid tape" inside the PSU but it proved ineffective and they ended up concluding that the main source of whine was the motherboard.
It's funny that the first device that introduced me to coil whine was the PS5. I'm not even sure whether my RTX 2070 has it, it being in a thick PC case under the desk and fan noise might mask it enough, I guess
. Sony's novel hardware choices in relation to the console paradigm (making a narrow and really high-clocked design) made it really the worst-case scenario when it comes to introducing coil whine by drawing high power and it's clearly not their top concern right now, as probably every PS5 has coil whine to some extent, but varying in intensity, like in my friend's case - he got the worst fan, but has very minimal coil whine (maybe he got a better deal than me after all, as fan noise might be subjectively less annoying than coil whine buzz
).
I guess the solution apart from trying to live with it or mask the sound is trading for a slim when it arrives (or pro if it exists, but what if it too pushes the envelope on clocks
?).
