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

Used as replacement fan on raspberry Pi

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

Before now, Ive only heard from others about how quiet Noctuas legendary fans are but actually hearing them for myself is really something else... maybe its because the fan I replaced was much noiser, but its mind-blowing how silent they were able to make these fans!

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.

Super super quiet that I am so impressed. It was worth the extra $12 for a fan. I have a raspberry Pi2 over clocked to almost the very limit and it cools it from 130F with heat sinks in an relatively open case sitting inside a closed media cabinet and brings it down to 95F and I cant hear the fan. I will try to listen for the fan in the middle of the night to see if I can tell. The one that came with the case was super loud. I didnt even think this new fan was even on, that is how quiet it is.

Worked perfectly, and included quality mounting hardware as well as cable adapters. I purchased this to use with a Raspberry Pi model B, and drilled a hole for the fan, and mounting holes to the side of a cheap case in order to use it.

Works with no issues. Very quiet.

This was an addition to my Pi 3, dilivery was fast. The fan fits in the case very well ans runs very quiet. It comes with rubber attachments that reduse noise.

I used this to replace the extremely noisy case fan on my Ender 3 printer. I had replaced the main board so I could choose either a 24v (which Noctua doesnt have as best I can tell) or 5v version. The original fan sounded like a jet engine when it was running and this one is virtually silent.
