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

This keeps my Pi 4 temps super low and it is very quiet. Add in the Noctua quality and this is a no brainer.

Best fan, works so nicely, and it’s soooooo quiet. I just wish it had a bit more cooling capacity.

Perfectly fits to my raspberry pi4 fan.

Used it for my Dreamcast and it was a great upgrade.

Have a Prusa printer with NF-A4x10 5v fan on it and it stopped working after 4 months. Tried contacting the customer support to [email protected] except my emails kept bouncing back. This is 100% the correct email, as even put in a ticket on the webpage and got an email from [email protected] which I tried replying and that email got bounced back. So, I just ordered another on Amazon and installed it. Really frustrating customer service as I get weekly emails from noctua support asking to hear back about my ticket but all my emails bounce. Tried to notify them of this problem by contacting them via the webpage again with a reference to the Ticket # but there was no reply. So, I took it even one step further and forward my email to another email address Google to Yahoo and their email still bounced. I believe they forward their emails through freshdesk which is causing the problems.

Very impressive!

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

Perfect. I used these fans to replace the POS fans that came with amcrest DVR. They are working very well and are super quiet.

I really like this. The noise level is much better after I change my fan to this one.

Used as replacement fan on raspberry Pi
