Featuring Noctua's AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8. The PWM version sports Noctua's custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 2200 to 1750rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua's trusted premium quality make it an elite choice for the highest demands.\u003c\/p\u003e\n\u003ch3\u003eSucceeding the award-winning NF-R8\u003c\/h3\u003e\n\u003cp\u003eNoctua's NF-R8 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 80mm fan. Thanks to its thoroughgoing aerodynamic optimisations, the NF-A8 provides higher static pressure and an even better airflow\/noise ratio than its much acclaimed predecessor.\u003c\/p\u003e\n\u003ch3\u003eFlow Acceleration Channels\u003c\/h3\u003e\n\u003cp\u003eThe NF-A8 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.\u003c\/p\u003e\n\u003ch3\u003eAAO frame\u003c\/h3\u003e\n\u003cp\u003eNoctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance\/noise efficiency.\u003c\/p\u003e\n\u003ch3\u003eStepped Inlet Design\u003c\/h3\u003e\n\u003cp\u003eNoctua's 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 and increases suction capacity, especially in space-restricted environments.\u003c\/p\u003e\n\u003ch3\u003eInner Surface Microstructures\u003c\/h3\u003e\n\u003cp\u003eWith 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 and improved airflow and pressure efficiency.\u003c\/p\u003e\n\u003ch3\u003eIntegrated anti-vibration pads\u003c\/h3\u003e\n\u003cp\u003eIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.\u003c\/p\u003e\n\u003ch3\u003eSSO2 Bearing\u003c\/h3\u003e\n\u003cp\u003eThe NF-A8 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability.\u003c\/p\u003e\n\u003ch3\u003eCustom-designed PWM IC with SCD\u003c\/h3\u003e\n\u003cp\u003eSupporting fully automatic PWM speed control, the NF-A8 PWM uses Noctua's novel, custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.\u003c\/p\u003e\n\u003ch3\u003eStops at 0% PWM\u003c\/h3\u003e\n\u003cp\u003eWhen the fan is set to 0% PWM duty cycle by the motherboard or PWM fan controller, it will stop. This makes it ideal for creating setups with semi-passive cooling that automatically turn the fans off and thus run completely silent at idle if thermals allow.\u003c\/p\u003e\n\u003ch3\u003eLow-Noise Adaptor\u003c\/h3\u003e\n\u003cp\u003eThe NF-A8 PWM is supplied with a (L.N.A.) that reduces the maximum fan speed from 2200 to 1750rpm. The L.N.A. can be used either to run the fan at a fixed speed of 1750rpm or to cap the maximum speed when using automatic PWM control.\u003c\/p\u003e\n\u003ch3\u003eExtensive cabling options\u003c\/h3\u003e\n\u003cp\u003eThe fan's short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows the connection of a second NF-A8 PWM fan to the same PWM fan header for automatic control.\u003c\/p\u003e \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv data-block=\"specifications\" data-scroll-amount=\"100\" data-scroll-top=\"true\" data-trigger-css=\"d-xl-none\"\u003e\n\u003cdiv\u003e\n\u003ch3 style=\"font-size:16px;font-weight:700;margin-top:24px;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border-collapse:collapse;width:100%;font-size:14px;margin-top:8px;\"\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eSize\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003e80x80x25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eMounting hole spacing\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003e71,5x71,5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eConnector \u0026amp; pin-configuration\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003e4-pin PWM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eCable length\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003e20cm + 30cm NA-EC1 extension cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eBearing\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003eSSO2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eBlade geometry\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003eA-Series with Flow Acceleration Channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eFrame technology\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003eAAO (Advanced Acoustic Optimisation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eRotational speed (+\/- 10%)\u003c\/th\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:9px 14px;\"\u003e2200 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth style=\"border:1px solid #ddd;padding:9px 14px;background:#f8f8f8;width:35%;font-weight:600;text-align:left;\"\u003eRotational speed with L.N.A.
