Extremely loud.

I normally would not write a review about a case fan but this fan is amazing. The quality is the best I have seen in a small fan. Most small fans are of course made in China but this is made in Austria and while it may be ugly (brown) I dont care.

Bought this fan to replace the super loud fan on my large Netgear 24 port switch (GS724T v2) and it went from sounding like a hair dryer to whisper quiet. Love it so far.

Worked great for replacing amcrest loud fans!

I used this to repair a fan in an old ClearOne XAP 800. It worked beautifully without making a lot of noise. The installation kit was very complete and i didnt worry a bit about it possibly not being able to connect. It has been running non-stop now for a month or so with no signs of slowing down.

Mine came with a omnijoin adapter for a 4 pin connection. The fan has a 3 pin connection and it will not fit. Might increase my rating if noctua sends me the right part.

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:

If youre looking for the fan needed to retrofit into a VA1 or 2 Sega Dreamcast, this is what you want. It just requires a couple of 3D printed parts and a wire adapter you can get for about $12usd along with this fan. Turns a somewhat quiet DC into a nearly silent one. Highly recommend to use Noctua over anything else. The quality of it sets the standard everyone else should be following.

Dreamcast people, this is the one.
