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

This is the best fan Ive ever had. Its super quite, but it also flows enough.

Awesome fan without the hideous colors of the original Noctua fans. Doesnt come with all the accessories the original one did but if you want the same quality fan at a cheaper price, I would highly recommend these.

These fans were a great improvement over my Yate Loons. Those were 8 years old, so that may have been the cause. Not silent, but a substantial difference. The only reason this is 4 stars is because the corners do not match the image and thus the chromax anti-vibration rubber mounts I purchased do not fit. They have two long rubber extensions to go through the two outer holes (while the screw goes through the center hole), but these two holes dont exist on the fans I received. I had to jerry-rig the things, cutting off the extensions and 2 mm from each end to make them somewhat fit. Very strange.

Great value and very quiet.

I am using these fans as intake for my pc and they are dead silent! for the price they cannot be beat. The cables feel solid and there was no noticeable noise from the fan motors. Airflow leaves a little to be desired and the quality is a clear step down from the premium noctua alternative, but for the price who cares!

Works as expected

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.

This is the quietest fan Ive ever installed. I have since replaced every fan with this brand.

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.

I bought this to replace a stock fan for my Fractal Design Define 7 Compact case and its working nicely! Now days theres no excuse not to have a quiet PC, the age of PCs sounding like a mini jet engine are now a distant memory; a relic of the early 2000s. All you need is good fans like this set up properly.
