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

Worked so well I bought another. A bit noisy for sure, but a fan controller calmed em down enough. If it was just a little quieter it would be perfect.

Great value and very quiet.

Very quiet

great

I replaced a much stronger noctua fan that sounded like a jet. Sure it pushed a lot of air but so does this one and its nearly silent at max rpm. I play my PC games on my couch about 6-7 feet from my PC which has 4 of these and I cant hear it...at all

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.

Never had an issue with a Noctua fan. Works as expected. Silent.

De buena calidad, lo único es que no trae los cauchos de amortiguación en las 4 esquina, pero está bueno el producto.

I was worried that this might be too loud. I am happy with it. I bought 4 fans for my new desktop and they are great.

Noctua recommends the 12B for case cooling on their website while it recommends the P-12 for radiator cooling, despite the P-12 having 12 more CFM at max RPMs. So I got my hands on an equal number of P-12 and S12Bs (this model) and outfitted a Mesify C (a very typical mid-range case) with them to see how it would cool. The testing methodology was simple: ambient, miduse, and aida64 full throttle. In all circumstances, the P-12 performed better by at least 3 degrees. The Aida64 screen shots are attached, and it shows that an overclocked processors cores are cooled at almost four degrees better by P-12s.
