Noctua NF-A20 5V PWM, Premium Quiet Fan with USB Power Adaptor Cable, 4-Pin, 5V Version (200x30mm, Brown)

This is the Rolls Royce of PC Fans; high quality components, and a highly efficient SS02 Bearing, and low energy usage. Everything is supplied in the well presented pack including the USB adaptor for PWM operation.The operation of the fan is like a whisper; gentle breeze; so quiet. The PWM 5V feature is just what I needed, so although it may appear expensive for a PC fan, this really is worth the money for a well designed fan with a 6 Year Warranty to boot!

Got when it was really hot, it's nearly silent, and noise isn't annoying to my ears, but that's personal preference. Ran of a usb power bank at night to provide quite airflow across head whilst sleeping. Probably not what it was designed for but worked a treat, no it's not a full on breeze it's just a gentle moving of air but it worked. As a pc builder noctua fans always score highly in my opinion, they cost more than you'd like but they do what they say they will!

I bought this fan to modify a BESTÁ Ikea TV Unit so I could keep my PS4 Pro hidden. Because of this there isn't enough ventilation in the BESTÁ unit, the PS4, with the door closed, would get extremely loud and hot. I used to just open the cupboard door whenever using the console. Having to get up to open / close a cupboard door seems wasteful when the PS4 is designed such that you should never need to touch the console if you don't want to (turn it on via the controller, download games, etc)After using a dremel to cut a curcular whole out of the back of my BESTÁ unit I mounted this using the provided screws and plugged the USB cable into the PS4.The Fan now comes on when the PS4 is turned on and provides more than enough ventilation to keep the PS4 cool and quiet, without having to open up the cupboard door!

Had this product a few months and has worked flawlessly. Has the ability to be controlled by an App making it convenient when changing colours.Good build quality too. No downside to this product so far.

I bought this to cool my avr. It’s replacing a pair of 120mm ac infinity fans. It does the job of cooling well but it seems louder than 18db because the previous fans were also 18db but were much quieter. Other than that everything is as expected.It would have been nice if there was a fan speed control and to have an option of black. The brown colour wouldn’t be a problem inside a pc case but when on top of my avr where everyone can see it, it look nice.

great product

Moves a lot of air, silent and has that brilliant, non-RGB, ugly Noctua look - perfect.

I use the fan to keep my sons console cool but it’s very noisy and every now and then (at least 4/5 times a day) it just stops and you have to unplug it and restart itI did get 2 of these I still haven’t tested the other one

I bought this to make a diy air purifier from furnace filters and WOW it is quiet even at max power. Max power being 800 rpm but still, amazing. I just wish it didn't look like a prosthetic limb.

Tienda ya casi 2 años conectado a un cargador y funcionando al 100% es muy silencioso.

For years I have been hearing about Noctua fans and products, but I never actually owned one. This is my first fan and I am very impressed. I had a 200mm Thermaltake fan but it was making weird squeaky/rattling noises and it was not even that quiet at 800 RPM either, to be honest. I decided to splurge a little and go for Noctua - and it was definitely worth it. Noctua at full speed makes only a pure "whoosh" sound, no squeaking, no rattling, no whistling, no whine, no high-pitch noise; just a pleasant breeze-like whoosh throughout the PWM range. And I need to focus to even hear it at 800 RPM, while pushing more air than Thermaltake. Beautiful.Highly recommended.

Para lo grande que es y la cantidad de aire que mueve, es muy silencioso.Es el segundo tamaño que compro de esta misma marca y encantado con ellos.Todo un acierto

La ventola crea un buon flusso d'aria pur restando silenziosa.Per alimentarla è sufficiente un vecchio caricabatteria da cellulare. Comodissimo se non la si utilizza in un cabinet da PC. Oltretutto il cavo USB tipo A è incluso nella confezione.
