Noctua NF-A8 FLX, Premium Quiet Fan, 3-Pin (80mm, Brown)

The fan looks well designed, is well packaged, and has several cable options included - but NOT one for two-pin operation. This is also a 12-volt fan, NOT a 5-volt fan. One reviewer replaced the original fan in a GSV-4000 power supply (exactly the same as mine!) and said that it worked perfectly. Lier, lier, pants on fire! It will not work with that power supply. (period) It was on the basis of their review that I bought this fan. My loss. Now I am the proud owner of a useless fan. Maybe I can use the vibration isolation mounts somewhere else.

Noctua makes good, quiet fans. I replaced the noisy fan in a Kenwood TS-2000 radio with this one and am very happy with how much quieter the radio is now.

great silent fans. Got it to make my UNRAID Storage server a bit more quite. Before it sounds like a jet airplane. Now it just sounds like a car.

Installed in a Synology DS1515+. I expected them to be quieter than the factory installed fans. However, from the start, I noticed little if any difference in noise level between these Noctua fans and the original fans. Now, after just a few months, these fans are make a buzzing sound. Going to reinstall the original fans.

They may cost a few bucks more but these oddly colored gems are super quiet and move a large amount of air.

Expensive but worth it if you need small, silent, high performance case fans. I have 2 installed in my SilverStone mATX FT03B

Dead quiet fan. FYI - this is now made in China but the quality seems to be there. Lots of options for where it gets power from. Mine is direct from the power supply Molex connector but cables are provided for other options.

I used this fan as an upgrade to the power supply fan on my Ender 3 Pro. I printed a new shell for it to house the significantly larger than stock fan and after the upgrade my PSU is almost completely silent and stays very cool. I also added a fan intake filter to protect the fan from any plastic debris from getting inside.

Super quiet and efficient. Installed 2 of them in a NAS for better airflow.

Great fan. As described. Many mounting and connection options.
