Noctua NF-A6x25 FLX, Premium Quiet Fan, 3-Pin (60mm, Brown)

Bought these to replace the fans in my power amp. With the ultra low noise adapters, its like there arent any fans at all! Sublime.

Little to no noise

As quality as a fan can be. Nice. Very quiet.

I think these fans are overrated. I’ve bought several Noctua’s at different sizes. They all tend to have weak air flow. This one doesn’t blow much air and it’s relatively noisy compared to a cheaper NB fan. Although the NB fan also has poor airflow.

I always change the fans on all the amps I buy. No matter if its a home theater amp. They make 50% less noise than anything I have replaced.

completely silent and still keeping the 2U case mounted to my wall from over heating

I have a piece of studio gear that came with the loudest, most obnoxious sounding fan that is built inside a sealed unit, and yet its still is as loud as someones excited conversation in a quiet room.

Swapped out the fan in an Amcrest NVR for this one and it makes such a difference, even without reducing the fan speed with the low noise adapters included with the kit. The original fan was louder than my PC fan at full blast (which is fairly loud as well) and with the Noctua fan, the NVR is now quieter than my cable STB.

Fabulous. Finally, a fan not made to be as cheap as possible. Not all of us are making 100,000 of everything and want it for 50 cents!

The fan is extremely quiet even operating at full speed. Its well made and includes everything needed for effective and versatile mounting. There are two speed-reducing cable extensions to make it even quieter but for my application they arent needed. Ill look at this line of fans again for my future builds. Im very pleased with the purchase.
