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

Very pleased

Top quality fan

The fan on my eight year-old QNAP TS-669 Pros power supply finally began to fail recently, producing an unpleasant tone at odd intervals. After checking up the specs of the PS online, I found that the units fans were replaceable - and fairly easily too. As soon as I confirmed that the fans would fit, I ordered the 40mm PS fan as well as a pair of these 92mm to cut down on noise.

Another quality fan from Noctua that is whisper quiet... two thumbs up!

Replaced a few case fans with this model and was quite please with the quality and options, comes with numerous adapters for pretty much any connection, and comes with multiple options for mounting, highly recommend as an upgrade or replacement or even adding fans to your device.

A good replacement of OEM fans, if you want non-vibrating and quiet 92mm fan. The only con is the color palette, but, as its sort of Noctuas signature, theres nothing you can do about it.

I used one of these in the back of my Sliger Cerberus SFF case to exhaust hot air in a small mounting space. Whisper quiet unless running at max RPM. The fan comes with rubber pegs that can be used for a vibration noise-free install, standard screws are also included. The standard Noctua color scheme is a love/ hate affair, more so if you have case windows for showcasing, but these are fantastic quality fans.

Im running this in my ITX build. Its enough to cool my components without having me worry. My build: 8600k overclocked to 4.5ghz, EVGA 1080ti, 16gbx2 g.skill f4-3200c16-16gvk, asus z370i, and a thermaltake core v1. Im also running 1 Noctua NF-A20 fans in the front and 2 Noctua NF-A8 at the back. Been running great since August 2018.

Great as always!

Can you even go wrong with a Noctua product? Yes, they are expensive, but they are a performance product at a great price.
