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

Did the trick for my DVR, easy replacement

first time Ive used Noctua fan for a Raspberry Pi4. Im blown away, no pun intended. I replaced a chepo pi-fan came with a pi case. I can hardly hear it. Would buy again.

excellent fan would order again, very quite what a difference it made in my amcrest dvd recorder

Used as replacement fan on raspberry Pi

It is a good and quiet small 40mmx10mm thick 5v fan running at 4500rpm.The various connection wires and accessories in the pack come in handy for replacing a stock fan in my NVR. The fan itself is quiet. But the noise it generates is about the same as the stock fan replaced. The noise is due to the excessive blower air against the heatsink fins. It would be better for my case if there are 5v models that run slower at , say, 2800rpm to 3500rpm. I recommend this fan for NVR stock fans(typically last 1 year ) replacement.

Using on an odroid XU4 with the gdstime heat sink, fits the heatsink perfect, much quieter than stock. The Omnijoin Adapter is 4 pin and the fan is 3 pin, I realized this after I had spliced it to the original connector, ended up using the spare splices and hacking up the 3 to 2 pin adapter. Disappointing, but not enough to down rate the product.

Great product

I buy enough of these (apparently) that Alexa suggested I turn on auto-subscribe to buy more. WOW these fans are amazing - I keep finding excuses and places to swap these in.

Works beautifully with the Sega Dreamcast you just have to add a resistor and I 3D printed adapter shell.

This little guy was picked up by me for a replacement for the 40mm fan on the Raspberry Pi UPS hat, which leaves much to be desired even though the original was definitely above average for an RPi accessory. This Noctua baby-monster pushes SOOOO much more air compared to that one, and it is like seriously silent. Like, I cannot hear it. It sits about 5 feet from me much of the day, and Ive never noticed it.
