Noctua NF-A9 FLX, Premium Quiet Fan, 3-Pin (92mm, Brown)

I bought these for my Synology 916+ NAS. I first bought the other model SS02 by accident and realized it was 4 pin but the Synology NAS is only 3 pin. Returned those and got this one instead which fit perfect. I am running 4 Ironwolf 10TB hard drives in my NAS so definitely want to make sure these puppies are cool. The old fans were loud and just not moving air as well. Sure these fans are expensive for 92mm fans but if you just spend $1200+ on your NAS, keeping your drives cool as possible is your main priority. It's like buying a luxury car and filling it up with cheap gas. No, sorry. But I am super pleased with the FLX fans. Really easy to install them and they came with a ton of extra cables that I will probably never use. Probably the best packaging in a fan you can imagine. But when you are paying premium prices it's what you should expect. Now that I have them in my NAS, the hard drives are 2 degrees cooler. It may just be that the old ones were pretty dusty (see my pics) and the new fans are just moving air nicely. Overall, I would highly recommend this fan as it is super quiet but moves a lot of air. Not the cheapest but you are definitely getting a quality product here.

I recently purchased a OWC ThunderBay 4 drive dock. I thought its fan was a little noisy, so I replaced it with this Noctua fan. Now it's nice and quiet. I like it!This fan comes with some low-noise adapters that slow down the fan. I'm using the one that reduces the fan speed to 1050 RPMs, and it works great with my drive dock.

I got these fans for my retro gaming rig and found out the old motherboard doesn't really control the fan speed - it has them running at 100% all the time. I wanted to build a fan controller circuit from scratch, but then I found out Noctua had actually included low noise and ultra low noise adapters - I had mistaken those for short extension cables. Silly mistake, I know.Now my rig has decent airflow, and it no longer sounds like a jet engine during takeoff. It's whisper-quiet.Everything - the packaging, included accessories, the quality of the fans themselves - makes these fans worth the price.

Replaced exhaust fan in a Dell XPS 8000 today and this fan is excellent. Very quiet and good air flow.

Noctua is the most expensive fan, and well worth it. Look, the difference between a budget fan and a great fan is $10, so just do it.Comes with everything you need to complete the installation: adapters, screws, etc.Comes in packaging suitable for Tiffany's.Very quiet. The only small issue I had was I had difficulty getting the provided screws to bite into the plastic so I just used the screws from the old fan.General information: Make certain you get the size right. This client's computer, a 7-year-old HP Envy, uses a 92mm case fan. I almost ordered the standard 80mm til I measured the existing one.Even though it comes with header adapters, it's best to order the correct one (3 pin, 4 pin) suited for your motherboard. I'd read about instances of users getting a "system fan not installed" error, but not with the Noctua.Also, determine the direction of air flow before removing the old fan.Take a minute to order the correct one and you'll be happy with the results.

Moves alot of air and quiet

I replaced my stock fan on a Synology NAS DS912 with this Noctua fan but haven't noticed a huge difference. It's a decent fan, but the improvement in noise reduction and performance wasn't as significant as I expected. but a solid fan tho.

Fan included with the eGPU enclosure is loud and always on. This turned out to be a good solution. The enclosure uses Torx screws, but actually installing the fan only required a Philips head and was done in a few minutes. Works well, there's no fan controller so it runs constantly, but with the low noise adapter operation is silent.
