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

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

A pricey but high quality little fan. decently quiet, doesnt make odd noises or vibration like other cheap small fans.comes with a bunch of adapters to fin about any use case.

Piece of JUNK product screw that came with the product did not fit. when you try to contact customer Service from Noctua good luck getting any support. JUNK GARBAGE product and never again.

Bought for a RPI 4 ice tower. Didnt really need it but what the heck. Works very well and did drop temps by about 2 degrees over the cheap one. Was it worth it? Maybe, maybe not. Im happy though.

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.

The packaging is crazy for just a fan. This fan is way more quiet then the piece of junk cheap fan that came stock in my NVR power supply and case. The thing sounded like an aircraft taking off, but changing to this noctua fan made everything normal like it should be - whisper quiet now. Super impressed with this fan and well worth the extra few bucks. any future fans I get will be Noctua.

Noisy little fans. i purchased them to replace another ones ( louder ) thinking the positive reviews would reflect the outcome; sadly i think i paid too much for a little fan than i should.

I no longer have to listen to the outrageous loud fans in my security DVR.

Awesome cooling fan. Works great with ODROID C2, brought temps down from 69C to 32C. Extremely quiet and has a good airflow. Definitely worth the money.

Great product
