Noctua Noctua NF-A12x25 LS-PWM Fan - 120mmThe Noctua NF-A12x25 LS-PWM is a special version of the flagship model NF-A12x25 PWM and runs at a particularly low speed ex... moreworks . Thanks to aerodynamic design measures, it achieves an impressive silent cooling performance. This is made possible, among other things, by the narrow impeller gap of just 0.5 mm. Equipped with a 4-pin PWM connection , the fan speed can be regulated and is between 450 and 1,200 revolutions per minute. The fan runs extremely quietly with a maximum of 12.1 dB (A) and still offers an air throughput of up to 55.7 m³ / h (32.78 cfm) and a static pressure of 0.82 mmH2O.The features of the Noctua NF-A12x25 PWM fan at a glance:- SSO2 bearings for high performance, quiet operation and a long service life- 1,200 rpm and max. 900 rpm with low-noise adapter (LNA)- Volume flow of 55.7 m³ / h (32.78 cfm) at only 12.1 dB (A)- PWM control between 450 and 1,200 rpm- Integrated anti-vibration pads to lower the volume- Convincing quality with a six-year manufacturer guaranteeNoctua NF-A12x25 LS-PWM: quiet 120 mm fanThe NF-A12x25 LS-PWM runs at a reduced speed compared to the flagship model NF-A12x25 PWM and thus offers an exceptionally low volume development. The 120 mm fan rotates at 450 to 1,200 revolutions per minute and generates a volume flow of up to 55.7 m³ / h . Nevertheless, the fan achieved an extremely low volume of a maximum of 12.1 dB (A) . Ideal for all silent fans and semi-passive systems!One of the special features is the narrow impeller gap of only 0.5 mm. This allows extremely efficient operation with improved back pressure, which is particularly noticeable on coolers and radiators. In combination with the included anti-vibration sealing lip , this leads to less leakage currents at the gap between the rotor and the frame. The rotor is made of Noctua's Sterrox liquid crystal polymer (LCP). This is particularly strong and has a low thermal expansion.In addition, the hub area of the fan is reinforced with metal to improve stability. The impeller of the NF-A12x25 LS-PWM is on the suction side with so-called flow acceleration channelsfitted. These accelerate the air in the outdoor areas, so that efficiency is improved and the volume is reduced. The air flow is further optimized by the stepped inlet area and the microstructure in the inner area of the frame.With the Smooth Commutation Drive 2 , the NF-A12x25 LS-PWM has the latest drive system from Noctua , which reduces torque fluctuations and ensures smooth running. In order to achieve excellent long-term stability, Noctua has integrated the SSO2 bearing technology .Extensive accessoriesVibr Overclockers.co.ukDelivery: to United Kingdom Report | £28.99 | ![]() | |||
