Bearing Type: The bearing type is an important factor to consider when selecting a bracket cooling fan. There are several types of fan bearings, including sleeve bearings, ball bearings, and fluid dynamic bearings. Sleeve bearings are the most common and affordable type, but they tend to have a shorter lifespan and can be noisier than other types. Ball bearings and fluid dynamic bearings are more durable and can run more quietly, but they are typically more expensive.
