Noctua NF-A9x14 HS-PWM chromax.Black.swap, Premium Quiet Slim Fan, 4-Pin (92x14mm, Black)

I used this to replace my Scythe fan on the Shuriken 2. I heard some people say that it would perform worse as it has two less blades, but I am getting lower noise and a 2-3 degree temperature reduction on the Ryzen 5 5600X. High quality fan from Noctua as usual.

If you are buying this expecting a Notcua quality fan, DO NOT BUY. I had this and three NF-F12s except this was so loud. I highly recommend Notcua but this is a horrible fan. It is way too loud!

So much quieter than any other fan Ive used. Others are cheaper for a reason.

I added this to my Meslicious PC build to have some consistent airflow over my MOBO since I am running an AIO with no compatibility for other case fans.

I was unable to find thin fans like this one from other vendors, but this still exceeds my expectations. Noctua seems to always make great products that are quiet and effective.

What is there to say. It’s quiet and powerful.

Bought two fans to use them as front air intake inside Fractal Design 7 compact. Easy to install and good quality.

I didnt always pay -that- much attention to what fans I used. Most of the time, Id rescue them out of retired builds and cases, and recycle them into new systems as a sort of tribute to the predecessor. When I set out to build my Skyreach PC, which was my console-killer wet dream, I knew each part going in needed to be the best possible in its class. I initially bought the NH-L9i in Chromax Black and was so impressed by it, I decided to go full Noctua in this system. I replaced the GPU fans (noisy, kinda whiny and frankly too tall to fit) with these fans, and its been great.

As per the other reviews, I can also confirm at mid-high speeds, there’s a high pitched whine noise. I mean, these are much faster than my other Noctua radiator fans (which are whisper quiet), so my solution was to turn their RPMs down to <1200 to match.

so far my 2500k is staying cool with this fan OCed from 3.7 to 4.33ghz.. I can run at 4.4ghz with a stronger louder setup.. but I think I found the sweet spot in power consumption and heat at 4.33ghz with this fan!
