Noctua NF-A12x25 FLX Fan - 120mm

The Noctua NF-A12x25 FLX is the newest flagship fan from Noctua. Four-and-a-half years in the making, Noctua took commitment to the development process to the next level. Noctua's innovations achieve remarkable results thanks to the fan's aerodynamic construction, and this also results in benefits to its cooling performance - as well as its incredibly quiet operation. This is possible in part thanks to the incredibly small distance between the fan blades and the fan frame, and moreover the tight clearance of just 0,5 mm this improvement demanded of Noctua is an impressive technical feat. Equipped with a 3-Pin connection, the fan speed can be controlled using the Low Noise Adapter and the Ultra Low Noise Adapter to operate at 1.350, 1.700 or 2.000 RPM. As a result the fan produces at most 22,6 dB(A) and operates with very low noise levels for its airflow, which is up to 102,1 m³/h.

The Features of the Noctua NF-A12x25 FLX Fan at a Glance:

• SSO2 bearings for high performance, quiet operation and long durability
• Tiny clearance of just 0,5 mm provides incredible performance
• 2.000 RPM with just 102,1 m³/h & 22,6 dB(A)
• L.N.A. and U.L.N.A adapter slows fan speed
• Integrated anti-vibration pads for minimising noise
• Superb quality with 6 year manufacturer guarantee

The Noctua NF-A12x25 FLX in Detail

The new top model from Noctua achieves some impressive specs. The 120 mm fan spins at between 1.350, 1.700 or 2.000 RPM and offers airflow of up to 102,1 m³/h. The fan achieves an incredibly low noise rating of just 22,6 dB(A) at the highest speeds. This fan is ideal for silent PC enthusiasts as well as overclockers!

Manufactured utilising a new material known as Sterrox LCP together with a range of impressive and innovative aerodynamic optimisations, the NF-A12x25 FLX is very impressive. One of the unique features of this fan is its unusually tight clearance between the blades and the fan frame, amounting to just 0,5 mm of clearance. This makes for incredibly efficient operation as well as improved air pressure, something that is of particular use when twinned with coolers and radiators. In order to make this possible, Noctua opted for a Sterrox liquid crystal polymer (LCP) on the fan blades which is incredibly resilient and possesses an unusually high resistance to heat.

Additionally, the hub of the fan is reinforced with metal to offer yet more stability. Despite the impressive performance of the NF-A12x25 FLX, people who put a lot of value in the quietness of a fan's operation will be especially interested in this cooler. Flow Acceleration Channels help to accelerate the air outwards, meaning that efficiency improvements as well as noise levels are both improved when compared to previous generations. Another optimisation of note can be seen in the stepped inlet design paired with the inner surface microstructures that are embedded in the frame.

Noctua's Smooth Commutation Drive 2 gives the NF-A12x25 FLX is the newest drive system, reducing centripetal force and contributing to the exceptionally quiet operation of the fan. Noctua has also gone to the extent of integrating highly effective SSO2 Bearing Technology to achieve additional stability over extended periods of operation.

Vibrations are minimised by means of Anti-Vibration Pads and, if you would like to mount this fan on a radiator, Noctua provides Anti-Vibration Seals with the fan. Another included accessory is Low-Noise Adapter (L.N.A.) and an Ultra Low Noise Adapter (U.L.N.A.), both of which are included in the bundle and maintain max RPM at between 1.750 and 1.300 RPM. The connection to a 4-Pin Header is possible via the 3-Pin connection using an adapter. A handy 30cm cable extender for large cases rounds out the capabilities of the fan.
