The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua\u2019s AAO (Advanced Acoustic Optimisation) standard. Its square shape
\n and 140mm mounting holes (124.5mm spacing) make it ideal for use on
\nwatercooling radiators or as an upgrade for 140mm case fans. Featuring
\nsophisticated aerodynamic design measures such as Flow Acceleration Channels,
\n the NF-A14 further improves the renowned quiet cooling performance of
\nthe award-winning NF-P14. The PWM version sports Noctua\u2019s custom
\ndesigned NE-FD1 IC
\n for fully automatic speed control via 4-pin fan headers and comes with a
\n Low-Noise-Adaptor to reduce the maximum speed during PWM control from
\n1500rpm to 1200rpm. Its performance-oriented 1500rpm top speed and
\ncomprehensive speed control options make the NF-A14 PWM an elite choice
\nfor users who strive to strike a perfect balance between excellent
\ncooling capacity and superb quietness of operation, be it on
\nwatercooling radiators, on heatsinks or in case ventilation.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\"NF-A14\"\n\t\t<\/td>\nSucceeding the award-winning NF-P14<\/b>
Noctua\u2019s
\n NF-P14 fan has become a default-choice among PC enthusiasts looking for
\n a premium quality quiet 140mm fan. Thanks to its thoroughgoing
\naerodynamic optimisations, the NF-A14 provides higher static pressure
\nand an even better airflow\/noise ratio than its much acclaimed
\npredecessor.<\/p>\n<\/td>\n<\/tr>\n
\"NF-A14\"\n\t\t<\/td>\nSquare 140mm frame<\/b>
The
\n NF-A14\u2019s square 140mm frame with 140mm mounting holes (124.5mm spacing)
\n makes it a premium grade replacement for common 140mm case fans and
\nperfect for use on 140mm water cooling radiators, where its square shape
\n will ensure full coverage and best pressure performance.
\"button\"<\/p>\n<\/td>\n<\/tr>\n
\"NF-A14\"\n\t\t<\/td>\nFlow Acceleration Channels<\/b>
The
\n NF-A14 impeller features suction side Flow Acceleration Channels. By
\nspeeding up the airflow at the crucial outer blade regions, this measure
\n reduces suction side flow separation and thus leads to better
\nefficiency and lower vortex noise. \"button\"<\/p>\n<\/td>\n<\/tr>\n
\"NF-A14\"\n\t\t<\/td>\nAAO Frame<\/b>
Noctua\u2019s
\n AAO (Advanced Acoustic Optimisation) frames feature integrated
\nanti-vibration pads as well as Noctua\u2019s proprietary Stepped Inlet Design
\n and Inner Surface Microstructures, both of which further refine the
\nfan\u2019s performance\/noise efficiency. \"button\"<\/p>\n<\/td>\n<\/tr>\n
\"Stepped\n\t\t<\/td>\nStepped Inlet Design<\/b>
Noctua\u2019s
\n Stepped Inlet Design adds turbulence to the influx in order to
\nfacilitate the transition from laminar flow to turbulent flow, which
\nreduces tonal intake noise, improves flow attachment and increases
\nsuction capacity, especially in space restricted environments. \"button\"<\/p>\n<\/td>\n<\/tr>\n
\"Inner\n\t\t<\/td>\nInner Surface Microstructures<\/b>
With
\n the tips of the fan blades ploughing through the boundary layer created
\n by the Inner Surface Microstructures, flow separation from the suction
\nside of the blades is significantly suppressed, which results in reduced
\n blade passing noise and improved airflow and pressure efficiency. \"button\"<\/p>\n<\/td>\n<\/tr>\n
\"Integrated\n\t\t<\/td>\nIntegrated Anti-Vibration Pads<\/b>
Integrated
\n Anti-Vibration Pads made from extra-soft silicone minimise the
\ntransmission of minute vibrations while maintaining full compatibility
\nwith all standard screws and other mounting systems.<\/p>\n<\/td>\n<\/tr>\n
\"SSO2\"\n\t\t<\/td>\nCuscinetto SSO2<\/b>
The
\n NF-A14 features the further optimised second generation of Noctua\u2019s
\nrenowned, time-tested SSO bearing. With SSO2, the rear magnet is placed
\ncloser to the axis to provide even better stabilisation, precision and
\ndurability. \"button\"<\/p>\n<\/td>\n<\/tr>\n
\"Metal\n\t\t<\/td>\nMetal bearing shell<\/b>
In
\n order to guarantee the highest possible degree of manufacturing
\nprecision, minimum tolerance and excellent long-term stability, the
\nNF-A14 sports a CNC milled bearing shell made entirely from brass. \"button\"<\/p>\n<\/td>\n<\/tr>\n
\"PWM\"\n\t\t<\/td>\nCustom designed PWM IC with SCD<\/b>
Supporting
\n fully automatic PWM speed control, the NF-A14 PWM uses Noctua\u2019s novel,
\ncustom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive
\n(SCD) technology. By providing smoother torque impulses, SCD suppresses
\nPWM switching noises and thus makes the fan quieter at low speeds. \"button\"<\/p>\n<\/td>\n<\/tr>\n
\"LNA\"\n\t\t<\/td>\nLow-Noise Adaptor<\/b>
The
\n NF-A14 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces
\nthe maximum fan speed from 1500 to 1200rpm. The L.N.A can be used either
\n to run the fan at a fixed speed of 1200rpm or to cap the maximum speed
\nwhen using automatic PWM control.<\/p>\n<\/td>\n<\/tr>\n
\"Cabling\n\t\t<\/td>\nExtensive cabling options<\/b>
The
\n fan\u2019s short 20cm primary cable minimises cable clutter in typical
\napplications while the supplied 30cm extension provides extended reach
\nwhen necessary. Both cables are fully sleeved and a 4-pin y-cable allows
\n to connect a second NF-A14 PWM fan to the same PWM fan header for
\nautomatic control.<\/p>\n<\/td>\n<\/tr>\n
\"Warranty\"\n\t\t<\/td>\n6 years manufacturer\u2019s warranty<\/b>
Noctua
\n fans are renowned for their impeccable quality and outstanding
\nlongevity. Like all Noctua fans, the NF-A14 features an MTBF of more
\nthan 150.000 hours rating and comes with a full 6 years manufacturer\u2019s
\nwarranty.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
