How long do sleeve bearing fans last?
Good sleeve bearing fans can last up to 30,000 hours (and even more in some cases) at temperatures reaching 50 degrees C.
What is a fluid dynamic bearing?
The fluid dynamic bearing (FDB) was first used in hard disk drives. It is a modification to the standard sleeve bearing to improve the lubrication of the bearing, and thus increase the life span of the fan while retaining one of the most positive aspects of sleeve bearing fans, which is the low noise level.
Is fluid dynamic bearing good?
Performance: Fluid-dynamic bearings are made for high-performance rigs; they are generally preferential for sustainability and relative silence, while pushing the same or more air (measured in CFM) as other fans of their range.
What type of bearing does Noctua use?
stabilizing oil-pressure bearing
SSO Bearing Noctua enjoys increased popularity among enthusiasts due to its high-quality cooling products. The company’s top fan models utilize a propriety bearing called a self-stabilizing oil-pressure bearing (SSO bearing), and Noctua says this bearing has a lifespan of up to 150,000 hours.
Are sleeve bearings good?
Sleeve bearings offer better stiffness than ball bearings do, and as they have split halves, are easier to inspect or replace. As oil rings used for sleeve bearings are good only for high-speed operation, sleeve bearings are not effective for very low-speed applications.
Why sleeve is used in bearing?
Sleeve bearings (sometimes called bushings, journal bearings or plain bearings) facilitate linear movement between two parts. Sleeve bearings consist of a metal, plastic or fiber-reinforced composite sleeves that reduce vibrations and noise by absorbing friction between two moving parts using a sliding motion.

What is an SSO bearing?
The self-stabilising oil-pressure bearing (SSO-Bearing) system has always been at the heart of Noctua’s award-winning premium fans. SSO combines the proven concept of oil-based hydrodynamic bearings with an additional magnet that supports the self-stabilisation of the rotor axis.
Are SSO bearings good?
SSO compared to conventional sleeve and ball bearings The SSO bearing not only surpasses the quietness of conventional sleeve bearings but also the long-term stability of current top-of-the-line ball bearings.
