Noctua NF-A9x14 PWM, Premium Quiet Fan, 4-Pin (92x14mm, Brown)

I picked up the Noctua NF-A9x14 PWM because I needed a slim 92mm fan that wouldn’t sound like a jet engine, and it definitely delivered. It’s noticeably quieter than the stock fans I’ve used in the past, even when it ramps up. Airflow is still really solid for how thin it is, and it does a great job keeping temps under control in a tight case. PWM control works perfectly too — it stays basically silent at low speeds and only speeds up when it actually needs to. Build quality is exactly what you’d expect from Noctua: sturdy, smooth, and it comes with all the little extras (mounting hardware, adapters, etc.) that make installation easy.

Great quiet fans. Well packed with lots of adapters for different applications. I used two of these to modify an MSI 6600gt 2x OC graphics card, which has worked out great and is now very quiet and running much cooler along with new thermal paste by Noctua too.

i had been using a stock cpu fan/heatsink since i built my machine. the cpu fan was getting quite noisy but the heatsink is a great design. i couldn't find any coolers that i liked and didn't wanna spend too much on it either so decided to buy this case fan and attach it to my stock heatsink. first try was to use extra strong velcro. didn't last long. found a youtube tutorial that used cable ties so i got my small reusable cable ties out and after some time fiddling them through and around the heatsink (and after putting it on the wrong way initially) i made it work. in retrospect it really wasn't that difficult and now the pc has become considerably quieter. the original stock fan was 70mm, the heatsink was 90x70 so i thought i'd get a 90mm noctua to replace the 70mm one. it is working really well now. i then went ahead and bought a second noctua fan 90mm to put at the back of my case as the stock case fan was also pretty noisy i realised. I know that i will eventually replace all my case fans with noctua, they are just so quiet, it's amazing, the quality is outstanding. for the case fan i added the speed regulating and extension cable that came with the fan. i used the rubber mounts on the case fan, only 2 of them as there weren't more fitting holes. was a bit fiddly but once in place it's a solid setup even on 2 instead of 4 rubber mounts. was only fiddly because it's at the back of the case under the psu. FYI, cpu fan on 4pin and case fan on 3pin power. both work, 4pin with normal cable and 3pin with speed regulating cable.

I installed one of these into my Asrock A300 DeskMini PC back in 2020. Recently it started to intermittently stop working. Now this could have been me for not reading the small print and thus had been using an air duster every 6 months to clean it. So I ordered a new one. Turned up the next day and worked straight of the box. Wow this fan is so quiet I keep thinking it's not working. There's a faint hum (and you have to strain your ears to hear it) from the shelf it sits on other than that you can only tell its working by peering through the grill to see if its spinning. Would I buy another absolutely. Would I do anything different to clean it - yes don't let it spin when dusting it. I can only assume the fan spun too fast when I air dusted it, which caused some kind of damage.

I purchased a palit 4090 recently and unfortunately the fans were incredibly loud even at the lowest spin up speed of 30%. I decided to remove the palit shroud along with the 3 fans that came with it and replace them with 3 of these Noctua fans. A couple of cables ties later and my 4090 is now whisper quiet and doesn't surpass 67 degrees on load, all while only spinning at 30% I highly recommend these fans for any custom GPU cooling

This replaced a super loud, cheap fan in my PC making it bearable to have in the room. Great price, too.

Excellent fan. It arrives in a thick card box with lots of additional leads as well as screws and rubber mounts.for you to choose from. Honestly the packing is a bit over the top but I guess it inspires some confidence that you have bought a good product. As you can imagine from Noctua it's a great fan. I was very surprised by it's wide range of operation. It went all the way down to just 10% of it's rated speed. That's 200rpm. Which really is exceptional. It was pretty loud at full speed. Basically where mine was situated it was fine up to about 1200RPM. Beyond that I could hear it. At 1400RPM it was OK, but beyond that it was too loud. The only reason it loses one star is because of the horrible colours. Come on Noctua stop trying to be "unique" and just make all your fans black.

Cooling a i5 6600K with a noctua L9i cooler (achieved max 53 celcius with 3DMark 11 benchmarking, idle around 30) and using this fan (same fan that comes with the L9i) to cool a reference blower gtx 660 (I removed the shroud and attached to headsink with zipties) cause it didn't fit in my NFC S4M skyreach. Cools the 660 very well (max 76 celcius with 3DMark 11) with idle temps around 30-40 degrees. Very good results considering that fact that I used the low noise adapter which comes with this fan (and the L9i) which reduces the fan curve. At 50 cm away, you actually can't tell whether its on or off, its that quiet! Your breathing is louder than the fans at that distance. You have to make your ears touch the fans to hear a super low frequency hum that sounds just like wind blowing softly, no coil whine or any unpleasant noise at all. HIGHLY RECOMMEND for anyone seeking for a 0 RPM build, 10/10 for cooling performance and quietness.
