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

Bought this fan to replace the noisy fan inside the Lorex HD surveillance system I bought from Costco about 4 years ago. Reached out to Lorex support was pointless and a waste of time for a replacement fan from them. Instead, I bought this fan. It is easy to install:

What else is there to say. It is a Noctua fan so it works perfectly and is basically silent.

as expected

Needed a fan to replace the fan I have been using on my Raspberry Pi. 24 hour operation takes a toll on the fans I tried so far. Figured maybe if I throw more money at it and hopefully get a better quality fan. Only been in operation for 3 weeks so its too soon to tell but its been humming along nicely so far. Quiet operation plus the unit comes with 3 different mounting options and 2 different adapter cables if you arent using it in a 3 pin situation which I am not in using it with a Raspberry Pi.

These little fans are just awesome! Great packaging and quality! A++++

These fans are great!

Im using this to cool a raspberry pi 4,the fan works great, the only downside was the amount of cable that was there. Fitting all that cable(with the 3-2pin converter) into even a large case was not easy and definitely will block some airflow.

These are SO quiet I cant tell they are on even when sitting in my lap and powered up. Im using these for a cooling in a helmet and I tried a cheaper type fan but as soon as it was glued it the bearings started grinding and got too loud. These 5v fans will work amazing with a usb power connection in the helmet. Im currently testing the battery life before I put them in the costume. With 2 of them plugged in and sitting right next to me at the desk I cant hear them 1 foot away.

Dreamcast people, this is the one.

Used as replacement fan on raspberry Pi
