Noctua NF-S12B redux-1200 PWM, High Performance Cooling Fan, 4-Pin, 1200 RPM (120mm, Grey)

These are crazy quiet. Airflow seems great, at least my tower reads overall lower temps.

So quiet. I used this to replace a 20dB fan in a NAS in my bedroom. It is so quiet that I was not sure if it was running at first. After opening the case to verify, I was happy to see that Noctua has improved upon their already amazing line of computer fans. The added ability for this fan to be controlled by the motherboard was great because I use a minimal Linux system and do not have room for a dedicated fan controller. I have not found any problems with the fan so far, and it has been running continuously since the day I received it.

I originally mixed these in with my stock case fans. That was stupid. Once I removed all of the crappy stock fans, the noise level dropped to near zero. Quiet fans make such a difference!

These fans cool effectively at low rpm’s given you buy correct type of fans. I have static pressure fans as pull configuration on my 360 aio and airflow redux throughout rest of the case to exhaust. I previously had cheap antec 120m rgb fans, switching to these noctuas dropped my idle temps to about 32° down from 41°. Only gripe is pwm cables are fairly short so plan on getting extenders/hub if you have a larger case.

El producto llegó super rápido y es de la calidad de NOCTUA, no mete bulla y enfría mis tarjetas de video sin problemas

I guest part of the redux resulting in lower cost fans also means that the y-splitters normally included with Noctua fans are not included. I was kind of counting on using that part. Ordered some others. Looks like good quality, just beware of that difference.

Its a noctua. It works great, works forever, and in general just works.

These fans are dead silent. I have 2 of these as intake fans. If I put my ear up to them I can only hear air and a faint annoying buzz from my Wraith Spire. I just ordered 2 80mm Noctua Redux 1800 PWM fans for rear exhaust because I like these so much.

I need more and definitely will buy more of these.

I am a big fan (no pun intended) of Noctua products, and use their Chromax line on a lot of builds. But for projects where the fans aren’t visible or where a gray color scheme looks good these are a nice budget option. I used them on a white Corsair 4000D Airflow build with white Noctua anti vibration pads, and they match up nicely with the case color scheme.
