They combine excellent processing quality with high cooling performance and minimal noise. The self-developed fans from Noctua are also responsible for this, which are also available separately as a housing or CPU fan.
The NF-A20 is a silent 200 mm premium fan with an Advanced Acoustic Optimization (AAO) frame and several hole pitches of 154 x 154 mm, 110 x 180 mm and 170 x 170 mm. The award-winning A Series is now available in a 200mm format for the first time, delivers high cooling performance, and achieves a further improved silent performance thanks to advanced aerodynamic design measures such as flow acceleration channels.
Noctua's specially designed PWM IC for fully automatic speed control as well as the SSO2 reference class bearing guarantee superbe stability and excellent long-term stability. The modular wiring, the low-noise adapter and 6 years of manufacturing guarantee make the NF-A20 a top solution for the highest demands.
The impeller of the NF-A20 is equipped on the suction side with so-called flow acceleration channels. By accelerating the air flow in the critical outer regions of the fan blades, suction-side vortex detachments are reduced, resulting in higher efficiency and lower turbulence-induced noise emission.
Noctuas AAO (Advaced Acoustic Optimization) frames have built-in vibration buffers as well as a Stepped Inlet Design and Inner Surface Microstructures for even better performance / noise efficiency.
The anti-vibration pads made from extra-soft silicone reduce the transmission of minimal vibrations and are compatible with all standard screws as well as standard mounting systems or fan brackets used with CPU coolers.
The NF-A20 PWM supports fully automatic speed control via PWM and uses Noise's new, specially designed NE-FD1 chip. This new PWM IC integrates Nocturas Smooth Commutation Drive (SCD) technology that minimizes PWM switching noise and makes the fan softer at low RPMs.
The NF-A20 is equipped with the further optimized second generation Noctua's proven SSO bearing system. With SSO2, the backside magnet is closer to the fan axis, resulting in even better stabilization resulting in further improved precision and durability.
Despite its high performance, the power consumption of the NF-A20 is only 0.96W, which is very low. Thus, the NF-A20 is not only environmentally friendly but also helps you to reduce the power consumption!
Noctuas fans are known for their makellose quality and outstanding longevity. Like all Noctua fans, the NF-A20 has an MTBF specification of over 150,000 hours and comes with a full six-year manufacturing warranty.
