Fan for silent box 120mm PWM

Overview
When performance knows how to be discreet

The famous NF-S12B has long been a benchmark for enthusiasts around the world and has helped Noctua build its reputation as a market leader in high-end silent cooling components. The brand new Redux series revives this famous model with a well thought-out and moderately priced offer that focuses on the essentials: the high-end NF-S12B fan.
The NF-S12B redux is equipped with an industrial-grade bearing - the SSO Bearing - and boasts an MTBF of 150,000 hours; complemented by a 6-year manufacturer's warranty, this premium model is a must-have and offers Noctua quality at an attractive price. The ultra-slow 700 rpm model is ideal for applications requiring a very low noise level or for those who are very sensitive to noise and require almost silent operation.

A proven fan
Thanks to its exceptional quietness, high performance and flawless component quality, the NF-S12B has become THE benchmark for quiet 120mm fans.
 The Redux series: aim for the TOP
All products in the Redux series offer excellent longevity and meet the expectations of the most demanding customers.
Optimum case ventilation
The ventilation of PC cases traditionally requires a high airflow combined with a moderate static pressure. The NF-S12B, specially designed to deliver high airflow efficiently and with low noise, provides optimal performance in these low impedance applications.
 Bevelled Blade Tips
By reducing the mechanical phenomena between the rotor and the stator, Bevelled Blade Tips increase the surface area of the blades while reducing noise. This optimisation is the key to the fan's amazing efficiency.
Smooth Commutation Drive 2
The latest version of Noctua's Smooth Commutation Drive system ensures smooth operation by eliminating torque variations and switching noises. This makes the fan very quiet, even at close range.
 SSO-Bearing
By combining a hydrodynamic bearing with an additional magnet, SSO-Bearing technology significantly enhances the fan's performance, while ensuring a cathedral-like silence.
Optional accessories
With anti-vibration seals, 3/4-pin adapters and Y-cables, this range of Noctua fans has a wide range of accessories to meet the demands of your configuration.
 6 year manufacturer's warranty
Noctua fans are renowned for their reliability. The Redux series has an operating time of up to 150,000 hours and comes with a 6-year manufacturer's warranty.
Exclusive PWM circuit with SCD
Enabling full automatic PWM speed control, the fan uses the newly developed proprietary NE-FD1 PWM IC which incorporates Smooth Commutation Drive (SCD) technology. By promoting less abrupt torque pulses, SCD eliminates PWM switching noise, allowing the fan to remain quieter at low speeds.

    Good Noctua, but...

    I took these 3 Noctua fans to make my gaming PC quieter, and for once these fans are not suitable for this purpose.
    Indeed, Noctua has several references in 12 with different speed, noise and blast speed and power... It's a shame I forgot about this :)
    It's a shame I forgot about it :) In short, I should have chosen the 1300 which will do the job properly (order already placed).
    These 1200 on the other hand are great on my external 360 radiator.
    So remember to choose well according to your needs and 8/10 for not putting this crucial information forward.

    From Noctua...

    Equal to its reputation. Not top of the range for this price (no silicon pad to isolate the fan) but quiet enough for my eyes or rather ears!

    More silent than powerful

    I had a slight problem with overheating due to my choice of a tower that was not sufficiently ventilated, so it did not help me with the flow rate.
    Otherwise, the sound level is absolutely perfect.

    Efficient, silent... In a word: Perfect!

    Wanting to improve the cooling of my case, I let myself be tempted by this Noctua 12cm. Well, I totally confirm the good reviews about it!
    Good airflow and especially really quiet!

    A choice to make with closed eyes!

    As usual, LDLC.com has done a great job on the delivery. Always on top!

    Very quiet

    Bought as a replacement for a standard fan (entry level), big acoustic difference!
    Easy to assemble, just needs the rubber fixings to make it perfect (supplied with 4 screws only)
    LDLC: Pro and fast as can be.
