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

Great fan. Added to my NH-D9L for a little extra umph in cooling.

No noise, I have to look to see if it is running. Highly recommended!

Quiet and reliable.

Using this fan on a Kraken G12 to cool my GPU. Incredible RPM range, and of course this Noctua fan is just as quiet as the rest of their line. I appreciate the rubber tips on the edges to prevent vibrations.

I replaced the stock fans in the two XEONs of a Supermicro motherboard. Very quiet, keeps CPU temp at 40C during memtest86_

I have been using Noctua for years, it is a high end fan I use for most PC builds, this is not a value added item because Noctua is a high cost brand, to half justify the cost they do perform as intended by manufacturer.

Es muy silencioso, queda muy bien como segundo ventilador del disipador.

Very silent fan my son loves it his computer is not making any nose I recommend

The noise level advertised is using one of the resistor cables that come with the kit to limit the speed to 1500 RPM. If you install them without the resistor cable they run above 2000 and are very loud.They are what I would say is normal at 1500…They are not 17 dB… I can assure you that. My Iwatch said 62…I’m sure it’s not accurate, but I’m sure it’s not 17. They move a lot of air though.

A bit more expensive than most fans of the same size, but they are rather quiet and will move air effectively. I have a pair in the front of a rack-mount computer case and it does the job well, quietly.
