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

These are fan-tastic! 3 mounted in the my tower and I cant hear them and not problems with temps.

The best fan money can buy, super quiet! I barely hear my Plex server running with a handful of these installed. Highly recommend.

The Redux fans are every bit as quiet as Noctuas premium fans and seem to move equal amounts of air. All at about half the price.

great product!

Great value and very quiet.

Excellent, quiet fans. Make sure to check that they push enough air for your application, as their the lower cfm type.

Works as expected

Great fans, excellent air flow, I have been using Noctua fans for a few years now definitely worth the price, have 2 on the top of my case pushing air out, keeps my FX-8300 and R9 290x cool.

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.

Ive seen tests and reviews of this fan, but plugging it in and putting my hand over it to feel airflow...my corsair fans and old scythe fan (which i was replacing) have twice the airflow as this one. It comes in a nice box, it has a long lead with nice insulation, but airflow is the reason i buy fans. This fan has a very aggressive blade pitch so I was expecting very high cfm output even at low RPM but in reality I just dont see it.
