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

Swapped the rear 92mm OEM Coolermaster fan out of a HP Omen 30L with this. These cases are basically miniature ovens, so I was forced to swap the stock cpu cooler with a top mounted AIO also. I wanted a rear fan that was quiet and didn’t move a ton of air so the rad fan could get most of whatever fresh air made it to the top.

Good fan. I have no complaints about the fan itself. I was really irked about the big model number stamp on the fan but it came off with some alcohol and A LOT of rubbing.

This fan saved me from destroying my ASUS pre-built system. The 92mm exhaust fan was loud, this fan makes my wife happy when we both work from home. Virtually silent, even during normal/high load.

I replaced the ugly orange and red fan that came in a Thermalright heat sink with this. This is thinner at 14 mm and more powerful and quiet too. A great buy for a small form factor system.

This fan is VERY quiet and a good pick for a almost noiseless fan!

more RPM = more noise

Noctua is great I guess because everyone says so. Im running UNRAID and although I need to upgrade to something better, Im trying to keep this one going a little longer. Dropped $50 on two of these slim ones to fit between the plastic front panel of my Dell T30 and the case metal, and it fit! So points for being nice and slim. I plugged them direct to power (through a sata adapter/splitter) and holy crap they are super unbearably loud! Others have said the same thing....I should have listened. I probably should have realized that I needed a fan speed controller, but I didnt and now just a bit salty that Im sending another $25 to Noctua for their PWM controller. Im $75 into this, which is about $30 more than I had hoped to spend on extra cooling. On the plus side, my 4 10TB drives (2 in each upper and lower drive bays) are running cool as a cucumber around 35C after 9 hours into a preclear, so thats a big improvement from the 45-50C+ temperature warnings I kept getting. Hopefully when I slow down those fans to a reasonable noise level Il still have reasonably good temperatures...well see! If Im not happy Ill edit this post.

Replaced the factory fan on the power supply for my 3D printer. There was an immediate improvement in the sound levels. My modification to the printer also included replacing the factory cover on the power supply with one I printed allowing for significant increase in airflow. The power supply was moved from the printer cabinet so it was critical to reduce the overall noise the printer made.

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.

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.
