Noctua NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown)

Impressed with the great quality, real premium materials, design, packed, perfomance and nothing of noise. Now ill change all to noctua.

Well known for their quietness and quality. Comes with lots of extension cables.

I used this product to replace two 92mm fans on some workstation-class R17 LGA2011 air coolers. The ball bearings on those fans seem barbaric now that my new noctua fans have zero bearing noise, and a gentle woosh of air. And when one of my five currently-employed noctua fans wears out over the next six years, I know noctua will be there with a warranty service.

I switched out all my fans and the CPU cooler for Noctua products. Under no load I cant hear the system at all. At full load its whisper quiet. Need I say more?

Moves a crazy amount of air at very little noise. Highly recommend

Super smooth and quiet cpu fan.

Simply put i used these fans to replace some PWM fans in my home server. These fans replaced two high power fans in some 5 hard drive enclosures in the server. Well simply put what a difference they make for noise so much quieter and no need to keep them on a fan controller.

good fan

I assumed that fans could only be so good and the extra cost would only result in marginal performance, boy was I wrong!

This review is of the Noctua NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown). From a quality standpoint, they thought of everything - it is ultra high quality in construction. Every little detail to reduce noise has been thought of, from anti-vibration considerations to decibel output. I didnt know squat about Noctua, but its clear to me that they focus on building quality products.
