Fan Speed, Bearings, and Noise - AC Infinity
But at higher fan speeds, sleeve bearing fans are noticeably quieter and one-ball one-sleeve bearings noticeably louder. Fans are also noisier as they age regardless of speed or bearings. Because sleeve bearing fans have the shortest life expectancy, they will become louder at a faster pace than all other bearing types.
