Noctua NF-A4x10 5V, Premium Quiet Fan, 3-Pin, 5V Version (40x10mm, Brown)

This fan it an excellent replacement for any cheaply made electronics cooling fan, (dvr, pc, game console, etc.)!

I purchased a couple of these to replace the cheap fans used in an Amcrest Security Camera DVR system and wow, what an amazing difference. It is super quiet and I can barely tell the system is running anymore. I will definitely keep Noctua fans in mind for future builds.

The fan is quieter than a typical cheap fan you can find online. However, it doesnt seem to be as quiet as I would expect for a fan from Noctua especially at this price point. However, this being a 5V fan, it does work quite nicely off USB power (adapter required).

Great little fans. Excellent quality. It includes everything you need to install. Also, very quiet. Cant even tell if theyre on.

Its definitely quite, using it currently for my Valve Index and it you can barely hear it. Does improve the heat dissipation from the headset quite well as it takes more ore less 1.5-2.0x longer (FOR ME) to have to take it off for being too hot.

I bought two to replace the noisy OEM fans in a video matrix and the difference is extremely pleasing. I had to look at the fan to be sure it was on. Air flow is low but comparable to the old fans. I spliced the fan connectors from the old fans onto the new using the connectors provided with the fan kit. The biggest problem I had was removing the old fans, their connectors were potted down to the board connectors.

much more quiet than other fans. Still, Id like it to respond to heat in 2 pin mode. Had to tear up the lnr cable to use the resistor for 2 pin mode. I installed it in a 320W Solid Gear PSU with a noisy fan. The air flow is the only noise, but whoa was it louder before I spliced in the resistor from the LNR. There ought to be a list of resistors to use. Im not an electrician or an EE. Im not going to watch movie with a vacuum cleaner on either.

Quiet and gets the job done.

I bought the incorrect voltage model, so this will be returned. It comes in great packaging, with very flexible options for adapters. I wound up buying two fans with the correct voltage to replace the two in the security system I have.

Slightly more cost than a cheap Chinese brand variant you find at neighborhood electronics store; this fan delivers on quality and reliability. You can tell as soon as you fire it up, its extremely quiet and moves volumes more air than the last unit. I installed onto my security camera DVR and couldnt be happier. I recommend this unit to anyone looking to replace a similar fan. This unit has several connector tips for different applications.
