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

I purchased 3, 2 worked great. Third one out the package did not work

I was very disappointed in this fans noise level. I have other Noctura fans in my system and am very pleased w/ them but this one was way off the charts in noise level. I used a generic one instead thats virtually silent.

Quiet and gets the job done.

Completely silent. Easy install in my raspberry pi 4.

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 love Noctua fans for my desktop and I love Noctua fans for my SBC projects, too.

Works as expected

When it outputs air from the Raspberry PI 3 its very noisy. When I flip it to blow air into the case its much better. OK I guess.

The best. Period.

Very Happy with this fan, quieted my DVR to near silent!
