Noctua NF-A12x25 PWM korpuso ventiliatorius- 120mm

Aprašymas

The Noctua NF-A12x25 PWM 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 4-Pin PWM connection the fan’s speed can be regulated to between 450 and 2.000 RPM. This means the fan produces at most just 22,6 dB(A), an incredibly quiet result, especially considering the impressive 102,1 m³/h of airflow and the static pressure of 2,34 mmH2O.

The Noctua NF-A12x25 PWM in Detail

The new top model from Noctua achieves some impressive specs. The 120 mm fan spins at between 450 and 2.000 RPM resulting in up to 102,1 m³/h of airflow. However, most impressive is the fact that it achieves this with exceptional noise output of a maximum of just 22,6 db(A). This is ideal for silent PC afficianados and overclockers!

Manufactured utilising a new material known as Sterrox LCP together with a range of impressive and innovative aerodynamic optimisations, the NF-A12x25 PWM 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 PWM, 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 PWM 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 a Low-Noise Adapter (L.N.A.) which reduces the maximum RPM to just 1.700. Should users wish to drive two fans on one connection, a 4-Pin Y-cable is also provided. One 30cm cable extension is provided for users’ convenience should the fan be used in a larger case.
