Welcome to the forums, newcomer!
Everyone's perception of sound will vary from one person to the next. There's also the matter of ambient noise. You could take a look at the
Be Quiet! Pure Rock Slim 2 though there's also Noctua to look into among other brands. Mind you, I parsed suggestions without knowing where you're located, what your budget is, what your preferred site is and what the make and model of your case is. They will all play a role in what cooler you can put in your system.
