The NF-A9 is a successor to the NH-B9 fan, and has a higher 2,000 RPM when seen against the 1,600 RPM of the NH-B9. It is also slightly louder at 22 dBA to the 17.8 dBA generated by the NF-B9. The fan features the latest iteration of Noctua’s self-stabilizing oil-pressure (SSO 2) bearing, which is claimed to be more durable and quieter than fans based on traditional ball bearing designs.
