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

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.

Drops temps by 28 degrees on Raspberry Pi 4 and I cant hear any noise from 3 feet away at least!

This fan works great and comes with a lot of accessories as well as cool packaging. Definitely higher end quality all the way around

Highest quality. Definitely worth the extra cost for Noctura products. The packaging and accessory installation options included are great! Fan is very quiet and moves a good amount of air. I purchased two of these to replace a CPU and case fan for a DVR.

The fan can be connected successfully by cutting down the 3 pin cable connected to the fans, connecting the wires with the 2 OmniJoin adaptors (including in the pack) and ignoring the yellow wire.

As described

Pretty quiet, and reliable. I had bad experience with cheaper cost fans because the bearings would go bad almost right when the return period would end. Happy with these

I 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.

This with a 3d printed bracket works well in the Dreamcast.

I bought this for a Raspberry pi4. Youll need a 40mm fan case mount and modify the plug leads, but it was worth it. :)
