Flyback transformers
in same vein, coil whine and display flickering, it happens here and there, but at least people started to noticing it, 2000s was a bad time for electronics, when you don't know if some piece of shit will be whining and you look like an unwell person in a shop trying to return it
"i'm hearing high-pitched noise at night from this power supply/motherboard"
"let's hear it"
"your own lights are whining, how can you hear it here?"
"not hearing anything, sorry, sir"
(also fuck early cfl bulbs, christ they were shitty, especially if driven with wrong voltage and thus flickering themselves to save 2 cents)
Got some tinnitus, now I never notice coil whine
