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

As expected, premium quality. Low noise. Way quieter than the fan came with raspberry pi 4 Cana Kit. Perfect for my mini raspberry pi 4 home server.

This fan is so quiet that I did not believe it was running. The air flow is a bit lower than I needed for my application, perhaps I just got the wrong model. The build quality is excellent and I am pretty sure the fan will last way longer than other. The fan blades also wont break like other fans our there, so it you need a fan where things might touch the blades accidentally, this is a good option.

Bought two of these to replaces the very LOUD fans that came with my Amcrest Security System DVR. These beauties work perfectly and now my DVR is unnoticeable.

This keeps my Pi 4 temps super low and it is very quiet. Add in the Noctua quality and this is a no brainer.

Did the trick for my DVR, easy replacement

I put this on my raspberry pi case. I used a dremel tool to create a bit more space for it, but it provides plenty of cooling so I can use it as an HTPC and server for my plex server. Very happy with it.

This fan was suggested by Amazon for use with the INVASION for Raspberry Pi 3, 2, B+ and 2B. If you are planning to use it with that device then beware...the chord that is attached to this little fan is much longer than you want to try and jam in that little case. We really struggled to try and make it work and even after all that may be returning the case because it just doesnt work as well as wed hoped. The fan however seems like it would be fantastic for the right case. May update the review if we can get it working in another case.

I absolutely love these fans. They do a great job in a sega dreamcast! The stock fan gets extremely noisy, or in my case just die altogether. I bought this fan and replaced my stock fan and it has made a difference in noise and temperatures! It’s so quiet that sometimes I have to check to see if it is even still running. I have a gdemu and that was bringing up temperatures. This fan brought them down. I loved the fan so much I added a second one just to circulate air from the rear vent. The next time one of my other dreamcasts has a fan problem I will definitely buy another noctua fan.

Its been a couple months and the fan is getting noisy. Used on my Pi4.

Used it for my Dreamcast and it was a great upgrade.
