Greater than one weekOverall a great little fan, but longer screws were needed. I used a rotary tool to deepen the screw holes.

> 3 dayUsing these on raspberry pi’s and the included wire connectors let me connect it up with Pi’s gpio pretty easily. Very handy to have when using poe hats that don’t have their own cooling, there’s enough airflow to keep everything cool. Will keep buying !

> 3 dayThese worked great in my Amcrest DVR. Mounting was done using cable ties and these fans have been working for a year with no problems. They are also a lot quieter than the original Amcrest DVR fans. I have heard Amcrest change the fans out with quieter ones but I can not guarantee that.

> 3 dayThis 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.

> 3 dayI 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.

> 3 dayBought this fan to replace the super loud fan on my large Netgear 24 port switch (GS724T v2) and it went from sounding like a hair dryer to whisper quiet. Love it so far.

> 3 dayI normally would not write a review about a case fan but this fan is amazing. The quality is the best I have seen in a small fan. Most small fans are of course made in China but this is made in Austria and while it may be ugly (brown) I dont care.

> 3 dayI usually pay a little extra for Noctua fans for my computers. They always outlast the computer that they are installed in. Ive bought two of these 5v 40mm fans to use on Raspberry pis now and I really like them. They are quiet, push plenty of air, and I know they will last a long time. Some people think the color is ugly. I dont mind the color, I actually kind of like it.
