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

Ive used the Be Quiet fans on several builds and these are just better. They feel more substantial and even at higher RPMs their noise is minimal. They also dont seem to have those ultrasonic or subsonic frequencies cheaper fans suffer from. I sit next to this computer all day long and Im very happy that I used these.

Great value and very quiet.

It might be a cheaper version but its still a Noctua, its got the usual Noctua traits. Its extremely quiet and the build quality is superb along with its amazing 6 year warranty. Overall a great case fan since its an airflow focused fan, but I reckon it should work alright on a heatsink or radiator as well at low RPMs compared to pressure fans as what I found out in testing is that Airflow fans only loses to pressure fans in the higher RPM ranges. And well since this is a low RPM quiet fan it should do a decent job at its RPM.

Greatbang for your buck

I bought 5 of these for my case. Installation was as you would expect, remove the old fans, and replace them with the new ones. I will say the included screws seem to be of a higher quality than those I pulled out of my case.

Bought as a replacement for my old and noisy case fan. Chose this brand due to its reputation for quality and low noise. It is absolutely dead silent. Considering buying another one to replace another case fan that I couldnt hear previously, but now can due to how quiet this fan is.

The best fans on the market. The redux fans man not come with all the bells and whistles, but the color is sooooo much better. The price helps a little too! I replaced a server fan with this guy and was able to drop the noise level very noticeably!

This fan is amazingly quiet!

I used this as rear/top exhaust on my NZXT H510 case. 120mm is the only size that this space accommodates and I swapped out the stock NZXT case fan. It is quieter and I was getting a few degrees cooler idle temps with just this change on the case (no other fans/coolers initally - was running Ryzen 5 3600 w/stock cooler and an OLD AMD GPU that is borrowed until I can decide on a card). I had read this was a top-rated air flow case fan and was quieter given the design. I would agree with those reviews/statements.

Everybody loves Noctua. They are VERY well-built fans, I agree. The highest quality materials, design, and construction.
