low noise ball bearings tests

Fan Speed, Bearings, and Noise - AC Infinity

The noise level emitted by a fan depends on various factors including the fans speed, age, and bearing system. Regardless of the bearing it uses, fans with higher speeds are louder than lower speed ones. At low speeds, comparable fans produce similar noise levels. But at higher fan speeds, sleeve bearing fans are noticeably quieter and one-ball
