This is what it sounds like on a computer’s fan, i manually clicked it on maximum speed for 30 seconds straight, recorded and edited on a iphone 13 pro device. Yes this is a laptop if you already know in the tags.
Mac ibook g3's cdrom working and producing various sound including some air noise from the spinning cd. Recorded very close to the cdrom with rode nt1000 condensor microphone through tlaudio fat2 tube preamp through rme hammerfall dsp audio interface.
