Noctua NF-A4x10 5V PWM, Premium Quiet Fan with USB Power Adaptor Cable, 4-Pin, 5V Version (40x10mm, Brown)

Noctua NF-A4x10 5v PWM Fan In my opinion, these fans live up to their premium quality advertisement. Build quality is excellent, noise is very minimal, and the 40 millimeter depth allows for extra airflow. You may not enjoy the color but I'm confident you will enjoy the quality and performance. Used to cool to steering wheel pedal sets they perform quite well and are nearly silent. Cooling is very efficient. These can be mounted with screws or with the included rubber grommets. Please bear in mind these are for 5 volt current not 12 volt. They will work with both PWM or direct voltage applications

I've used Noctua fans in several home-build computers. Great quality and whisper quiet. This Noctua NF-A4x10 5V PWM comes with mounting hardware and USB adapter cable. Plug it in to any USB-A power source and it's on. Compact and quiet. Small size does not provide huge airflow. Yet perfect for quietly cooling small electronics. I have it on top of our cable modem which gets very hot without a fan.

Worked extremely well for my usecase of keeping an NVME SSD cooled. The fan is extremely quiet, and I love the classic Noctua colors. It puts out a LOT more air than you'd think for a fan this quiet. Since installing it, the heavily used nvme SSD's temps have gone from therrmal throttling at 85c almost all the time, to a cool and comfy 35c. I simply drilled a hole in the top cover of my mini PC and attached the fan. Boom no more thermal throttling. It's perfect.

Zip tied this using the open vent grates to the top of a modern Seagate Expansion external hard drive. Added electrical tape to all other exposed area at the top to ensure the fan would have to pull cool air through the open grate at the bottom of the housing. SMART reported temps dropped from 50-55 degrees C under heavy load to not budging over 35 degrees C. Perfect fit for the 40mm case. The fan is fairly audible at full speed, but I will use PWM through an Arduino to control the fan speed dynamically with the drive temp. Great option if you need to keep small electronics cool! No idea what Seagate was thinking by relying on passive convection to cool such a hot drive, but this Noctua saved the day.

Just got the fan was on backorder for two weeks and so far very happy with it; I needed a 5V fan powered off USB, and this has both. Quiet as any other Noctua fan while performing very well. Use it to cool my Vive Wireless VR adapter that overheats after 30 minutes of use normally. The cable quality is excellent got a rubber sheath and heat shrink molding, though this is also a complaint as outlined below. Will likely buy one or two more soon to replace the aging (and loud) fans for networking appliances. Saw some reviews comment on excessive packaging, well this package is much more environmentally conscious, no huge plastic holders to all the different parts, just a cardstock box and fan holder. Not really negatives but if Noctua is looking for feedback, been replacing new computer builds with the Chromax black version, so hopefully Noctua can make these in black one day. I don't really need my fans to stand out; they just need to their job. My only real gripe is the cable is fixed length; since it's a small fan it's likely use in limited space environments that don't need such a long rubber sheathed cable. All my newer Noctua 12V computer fans come with a short connect on the fan and then few extension choices, this one is a fixed 30 cm cable.

Is it a good fan? So far, so good but we need to wait a few more years. It runs very quietly, moves enough air and seems well built. Why Lunchables? The packaging is ridiculous. Huge box (by computer fan standards), Velcro openings front and rear, little windows to gaze upon you new fan, compartments with an assortment of cables and adapters, rubbery vibration mounts, screws, etc., etc. For the record, I used the fan with attached cable and the remainder got tossed into the corner. So how did it work out. I mounted it on an Nvidia Jetson Nano. I had to use small nylon screws as the holes in the Nano heatsink are very small. As soon as I snugged down the screws, three of the four ‘vibration isolators’ on the corners on the fan pealed off. That’s ok, I don’t think they really did anything. I’m not excited about the cream and brown colors but I did have a couple (thousand) brown cable ties so they would match the fan and all-in-all, it looks ok. Overall function, build and design, five star but Noctua looses one star for the excessive packaging. (I’m feeling Noctua Marketing would disagree with me on the packaging)

It’s exactly what you want it for. Has great air volume for its size, fairly quiet from the easily controlled low speed to full speed, it’s the perfect size for those Pi projects, and it’s a Noctua fan. It’s built right, great price and keeps your small electronics cool.

Great fans. Very quiet and don’t seem to be cheap quality. Always a great upgrade fan

Increíble cómo algo tan pequeño puede mover tanto aire sin sonar como un mosquito enfadado. Lo he usado para sustituir el ventilador de serie de una impresora 3D y el cambio es brutal; ahora el silencio es casi total. Noctua nunca falla con la calidad de sus rodamientos.

Ok

Ventola molto silenziosa. Arriva con una ricca fornitura di cavi ed accessori per la sua installazione. La sto adoperando per raffreddare un hotspot su base Raspberry Pi 3 Model B Plus, che si sa scalda molto. Bene riesco a mantenere una temperatura compresa tra i 28° ed i 36°. Prova superata a pieni voti. Consigliata.

The added USB cable saved me a lot of headache. Really good documentation on the cable colors. All in all a very good fan :)

Es mucho más silencioso que el ventilador que sustituí con este además de que con el kit de adaptador incluido es fácil adaptar la conexión de la mayoría de los dispositivos . No
