Noctua NF-S12A ULN Ultra Low Noise 120mm Cooling Fan, 600/800 RPM The NF-S12S-ULN is a premium quality fan that offers full flexibility in quiet to ultra-quiet case cooling thanks to its Advanced Acoustic Optimisations.

Features: Noise levels from only 6.7 d B (A) High 43.73 CFM airflow Advanced Acoustic Optimisation Frame Two speed settings for maximum quietness Smooth SSO-Bearings Six year warranty Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO or Advanced Acoustic Optimisation frame. The NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The ULN version provides super-slow 800 / 600rpm speed settings for ultra-low-noise applications & highly noise sensitive users who demand near-silent operation. Its superb running smoothness, SSO2-Bearings & Noctuas trusted premium quality make it an elite choice for quiet case cooling. Noctuas Advanced Acoustic Optimisation Frame Noctuas AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctuas proprietary Stepped Inlet Design & Inner Surface Microstructures, both of which further refine the fans performance/noise efficiency. Anti-stall Knobs: What is Stall? Noctuas S12 series fans impellers use a high angle of attack in order to achieve superior airflow. However, impellers with high angles of attack are typically more prone to undesired stall & flow separation phenomena that can occur when the fan is working against higher impedance such as when blowing through tight fan filters or when used on heatsinks & radiators. In these situations when the fan is building up high pressure but less air is moving through, the speed of the air particles flowing alongside the suction side of the fan blades gradually decreases towards the trailing edge. The lower the speed & the higher the counter-pressure, the higher the risk of the air particles becoming detached from the blade surface. This flow separation phenomenon known as stall leads to undesired turbulence, reduced efficiency & translates into a dent in the fans performance curve. Integrated Anti-Vibration Pads Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws & other mounting systems. Smooth Commutation Drive 2 The latest version of Noctuas advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations & switching noises. This makes the NF-S12A remarkably quiet even at very close distance. Stepped Inlet Design Noctuas Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment & increases suction capacity, especially in space restricted environments. Inner Surface Microstructures With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise & enhanced airflow & pressure efficiency. Package Contents As expected from Noctua, the fan is well packaged & is supplied with both the usual fan mounting screws & also rubber fan mounts to isolate the fan from the case ensuring that no vibrations from the fan can reach the case. An in-line resistors (L.N.A) is included & this simply lowers the voltage & therefore the speed of the fan from 800 to 600 rpm if full speed isn't required. A Molex adapter allowing you to power the fan from the PSU & an extension cable are also included. Specifications: Size

Includes:: two sets of brackets in order to support both square & narrow type LGA3647 sockets. Thanks to pre-installed mounting screws & the included processor clips (square type & narrow type without Omni-Path fabric connector, with fabric connector on request), the installation procedure is easy, quick & secure. Compact 92mm size for best compatibility Thanks to its compact footprint (95x 95mm with center fan only, second fan can be installed on either side depending on available space) & a total height of only 134mm, the NH-D9 DX-3647 4U provides excellent PCIe compatibility & is small enough to fit most 4U size rack-mount enclosures. Dual NF-A9 PWM fans The NH-D9 DX-3647 4U is equipped with two of Noctua’s award-winning NF-A9 92mm fans in their high-speed 2500rpm HS-PWM variant. This push/pull dual fan configuration makes it possible to achieve a level of cooling performance that is remarkable for such a compact cooler & comes close to the bigger NH-U12S DX-3647. PWM support & Y-cable The NF-A9 premium fans supplied with the NH-D9 DX-3647 4U support PWM for convenient automatic speed control through the motherboard, which allows them to run near silent at lighter loads & to speed up only when necessary. The supplied Y-cable makes it possible to power & control both fans simultaneously from a single motherboard fan header. Pre-applied NT-H1 thermal compound Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance & outstanding long-term stability. Having the paste pre-applied to the heatsink base ensures optimal bond-line thickness & saves precious time in installation. Ideal for system integrators! Six year manufacturer’s warranty Noctua products are renowned for their impeccable quality & outstanding longevity. True to this legacy, the NH-D9 DX-3647 4U heatsink is built to last, & like all Noctua fans, the supplied NF-A9 units feature an MTTF rating of more than 150, 000 hours. The entire package comes with a full six year manufacturer’s warranty.
