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

Amazing little air mover that can add life to small electronics. Its slim at 10mm which makes it great for many applications where the bulky and more common 20mm thick fans will not fit. In fact its so slim a surface mount would be acceptable in many cases. I do wish that it came in different colors though.

Great fan - it blows!

Amazing fan. Saved me a bunch of time and money as its easy to install.

I read about getting my RP4 4gb Ram overclock will need to have a good fan. I got the ICE TOWER Cooler to it. I wasnt a fan of the LED Colored Fan so I changed it to Noctua fan before I put this thing together. Wouldnt be able to tell you how quite the original fan would be but my Noctua fan is great!!! It came with different plugs for different needs. Its worth it to pay the premium for the premium quality.

Was expecting a quieter running fan, given the brand. Works well though.

Day and night difference. When compared to the factory fan of my security system DVR, this fan wins by a landslide. The install was very easy, though I had to break of one of the plastic pins in the original connector to make the adaptor for the fan fit (no big deal). The product could take it one step further and provide a couple of small zip ties to make the job clean. Overall I am satisfied with this product and would recommend it to others looking for a quitter alternative to factory loud fans. Of last note, please do not expect to not hear the fan because you still will, however, it will be much quieter that the factory fan (at least this was my experience).

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.

Super super quiet that I am so impressed. It was worth the extra $12 for a fan. I have a raspberry Pi2 over clocked to almost the very limit and it cools it from 130F with heat sinks in an relatively open case sitting inside a closed media cabinet and brings it down to 95F and I cant hear the fan. I will try to listen for the fan in the middle of the night to see if I can tell. The one that came with the case was super loud. I didnt even think this new fan was even on, that is how quiet it is.

This product stopped working long before it should have... Cant return. I would have just replaced it with the same fan, but wasnt allowed that option. I have the same fans cooling my gaming PC. No problems.

Was looking for a fan to keep my raspberry pi cooler while I have it mounted on to a ender 3 3D printer and it does pretty good, even with it being in inside a enclosure tent for the printer.
