    The type of bearing used in a fan can affect its performance and noise. Most computer fans use one of the following bearing types: Sleeve bearings use two surfaces lubricated with oil or grease as a friction contact. They often use porous sintered sleeves to be self-lubricating, requiring only infrequent maintenance or replacement.
