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

Love it.

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.

Quiet operations and moves a lot of air as an exhaust fan. It doesnt come with any extensions or adapters but the 4pin cable is long enough.

Fantastic quality fan that runs super quiet. Im glad I found this lower end line of fans from Noctua as it saved just a tad bit of money and I actually like the color way better than their tan/brown combos on the more expensive versions.

I bought four of these to replace my two loud stock Corsair case fans along with the Noctua anti-vibration pads. These run more quiet and at a lower tone than the high pitch of my old fans. The side mounted fan should help with my GPU thermals, and I installed two more intakes at front and bottom of the case, with one exhaust out the rear. Ill pick up a fifth fan for top exhaust.

Super quiet and very high performance!

Under full load in stress testing it pushes plenty of air, and makes less sound than installing it did. Id find these fans worth it at double the price.

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

Replaced noisy fan, the difference is amazing. Alienware Auroa R9

Extremely quiet! Moves a lot of air. Pulse Wave Modulation (PWM) controllable. The Redux version of Noctuas fans are more reasonably priced than the full retail version and they are gray instead of tan. Its a win-win in my book. I have 4 of these in my PC setup and they are dead silent. In fact only the two on my CPU cooler even run most of the time and they only have to run at 30% to keep the overclocked i7 processor cool.
