Noctua NF-A8 FLX, Premium Quiet Fan, 3-Pin (80mm, Brown)

I purchased two of these fans to replace the two fans in my Synology DS1513+ NAS box. The old fans were over ten years old and the bearings were wearing out and creating noise. These new fans fit perfectly and eliminated my noise problem. I am very satisfied with this purchase.

I bought 2 of these fans to upgrade the stock fan in 2 Kenwood TS-2000 ham radios. It is thicker than the stock fan but there is plenty of clearance. The stock screws can be used in the rear of the mounting holes as they are not long enough to go through the whole fan. I may hunt down some long 2 mm screws someday to complete the installation but it works great as it is. The fan is much quieter than the stock fan and moves a lot more air - a lot more. You have to put your ear right up to the radio to hear the fan. This is great for cross band repeating, Kenwood Sky Command, or digital modes like PSK31 or JT65 that create a lot of heat. If you like it quiet you can even do this if you aren't running any of these modes. Keeping the heat down keeps the finals alive! . This is a high quality fan and it comes with lots of adapters if you are going to use it in a PC. The fan in the TS-2000 is ground switched so if you put a 1 watt, 100 ohm resistor between the fan ground and chassis ground the fan will run at low speed all the time and switch to high speed when the relay closes. It is an ideal fix.

I retrofitted the power supply in an old Compaq Deskpro EP with this. I wanted more airflow through the case without a ton of noise. The Nidec fan from 1998 would've been far too loud if I sped it up much. I took apart my power supply and disabled the fan speed control (even old ATX power supplies have fan speed controllers). I did this by only using the positive off the fan header and finding a different ground. The fan runs at full speed and makes a very pleasant low-pitched noise. This keeps the machine much cooler and will prolong the life of this old power supply. Noctua fans are great, I have them in all my computers. They are powerful air movers and even at higher speeds they stay quiet.

I used this fan to replace the stock cooler in my Behringer iNuke 3000 amplifier. The stock cooler was extremely noisy, even at base load. I have the amp setup in a home theater app so the loudness of the stock fan couldn't be tolerated. I swapped the stock cooler for this Noctua. All I can say is WOW. The fan is completely inaudible at base line AND under load. Granted, I don't think it moves quite the CFM as the stock cooler, but I've had no thermal overload issues so far. I'd definitely recommend this for someone looking for a high quality cooler that is SILENT. UPDATE: 09/28/19 I ran the amp at full tilt (almost to clipping) today and managed to trip the thermal overload fail safe. This was more of a benchmark test than a real world continued use. That said, the fan couldn't move enough air to keep cool under a max load, but it does just fine for normal use. Still 5 stars got quality and lack of noise.

Easy install and came with extra cable, screws and other necessary items for even the toughest installs and its whisper quiet. Great price and perfect service and delivery from Amazon. Thanks!

My Synology DS1515+ is well past its warranty date, and it needed a replacement fan. Previous experience has taught me that getting original parts from Synology can be a costly/slow/painful process. A few Synology forums recommended getting Noctua NF-A8 FLX fans as a decent upgrade, and they were right! These replacement Noctua fans run quietly, the case/drive temperatures are stable (no temperature increase over original), and DSM 7 is happy with them (no error beeps or system warnings). Glad I purchased a set of them for my NAS.

Super fan, lots of air flowing and very nice quiet hum. The Noctua fans come with an amazing array of power attachments to connect it, and control the fan speed. Also comes with silicone mounts and screws so you have your choice of mounting. Corner pads also make the mounting solid and quiet as they absorb vibration. Top of the line fan! I don't even look at specifications of fans anymore. I just look for the Noctua fan which is the size I want and then get it. Other fans may look better on paper, but you can't beat the Noctua engineering for a good balance of design, construction, longevity (6 year warranty), and durability. And let's face it - they're not THAT much more expensive. You'll easily forget the price difference in the long run.

It's a Noctua, so you know it will be a quiet, solid performer. And this one lives up to their reputation. Worked perfectly as a replacement for a stock cooling fan in an audio amplifier. Everything about this fan says 'quality', and I am continually impressed by just how superior the Noctua's performance is, over what can look like nearly-identical fans. They move more air, with much less noise, than any other fan on the market. And I have found this to be the case with ANY fan that Noctua makes - they are a superior company making a superior product. Worth the premium!

Noctua always produce top quality products - this is no exception. Note, this is the DC version - if you're fitting in a PC case pay the extra for the PWM version.

Tengo un NAS Synology DS1513+ desde hace dos años y siempre he encontrado muy molestos los dos ventiladores que trae de origen. Soy fiel a Noctua y me puse manos a la obra. Tras unos cuantos clicks por internet supe del tipo de ventiladores a usar y fui directamente a por unos Noctua NF-8 FLX que ya he usado previamente con otros tamaños y usos. Qué decir del cambio? La noche y el día como siempre, la reducción de ruido de funcionamiento fue drástica con los Noctua y encima con mas caudal de aire. La calidad de fabricación, como es habitual en Noctua, es de cinco estrellas. Estos ventiladores vienen equipados con todos los accesorios posibles y el nivel de acabado está al máximo nivel... eso se paga con un precio mas caro, pero finalmente las ventajas de trabajar en silencio ganan con creces el precio algo elevado. Producto totalmente recomendable con los ojos cerrados.

I used 3 of these in my mini nas with the Jonsbo N3 case. 2 Back exhausts and one front intake. And let me tell you it is perfect. The Noctua proprietary silicone screws are top-notch and allow for special use cases where normal screws aren't convenient/possible. Works well with the 4-pin Molex cable from any ATX/SFX psu.

3 Boyutlu yazıcımda kullanıyorum. Power Supply kısmı için aldım. Kullanmak için Thingiverse üzerinden başka tasarımlar bulup yerleşimini yaptım. Hava akışı çok iyi olduğu için Power Supply sürekli fanı çalıştırmıyor ve yazıcımın sessiz olmasını sağlıyor. Tam performansta sesi biraz yüksek olsa da hava akışı yeterli olduğu için bu eksisini götürdüğünü düşünüyorum. Tavsiye ederim.
