I have a corsair cx750m and its fan is noticeably the loudest component in my system. Its a low-pitched humming sound with a little bit of a whining noise to it. I'm definitely not overloading the PSU (I have a 65w tdp CPU with a r9 270x and a single hdd) so I am guessing this is just how the psu sounds. Would it make more sense for me to buy a fanless psu or are there quieter options.
