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

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

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.

Fans

Got this for a pi4b. Works. Yay Noctua!

Ive had bad luck with these tiny fans. This one is an exception. Very quiet, good construction. The wiring is very stout. I was impressed with both the packaging and the materials used. Im very happy with this purchase!

I used this to replace 2 fans in my amcrest dvr. It was simple enough to use, and my once loud annoying dvr, is a quiet place. The product is as described and there are several youtube videos available that help with modifications. I highly recommend this product.

really quiet fan.

Using this on a Odroid XU4Q. Silent as can be and cools well.

Works great (with a 3d-printed mounting kit). Now my DC will outlive me, and stay nice and cool.

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).
