NoctuaNF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown)

Noctua have an amazing track record for fans and this one is no exception. This 92mm PWM fan is of a great quality, but it also contains a variety of accessories in the box that often be more than enough for most installations.The fan itself is styled in Noctua's brown/beige colour scheme, and is silent in it's operation unless running close to the maximum RPM.Overall, this is a brilliant bit of kit. I used this as the exhaust fan on a PC case that I bought recently. It isn't my first Noctua product, and it certainly won't be my last!

Brilliant fans, super quiet

There's not much to say really. It's a Noctua fan, and as expected, the top cooling performance at low-level noise. The extra accessories are just a bonus!

This review is for the twelve volt & four pin version of the fan, installed into a renewed Dell Optiplex 9010 MT, purchased through Amazon.The fan is lovely & quiet. It's very easy to install, using the screws provided in the box. There are rubber grommet things in the box; I didn't bother with them.Please note: the Dell motherboard has a five pin header; a five pin (from the Dell motherboard) to four pin (to the fan's cable) adapter cable is required. These adapters are easily obtained.The above Dell DID NOT like the fan speed reduction cable included in the box: using this cable brought about a series of beeps, a pre-boot/POST (power-on self-test) error diagnotic screen & a refusal to boot to Windows. This was easily resolved by removing the fan speed reduction cable.In short: a very quiet & relatively cheap replacement for an existing fan; ample cables & fittings provided; very nice presentation with high quality packaging.A very good product & highly recommended.

The Noctua NF-A9 PWM was bought to replace the Wraith Stealth cooler fan (which does not live up to its name)! This cooler is bundled with the AMD Ryzen 5600x CPU but the fan used is not as quiet as it should be - an annoying low level ticking sound is produced by the fan motor which becomes more evident as the speed increases above 1500rpm. So I replaced it with the Noctua NF-A9 PWM and the difference is almost unbelievable. I cant hear this fan and to achieve the same CPU temperature, it only has to run at 60% of the original fan speed! This is an outstanding product both in terms of performance and value for money.

Noctua are renowned for making the best quality, durable and quiet fans. What more do you need? Highly recommended.The first Noctua fan I purchased was a cpu heats ink combo. It made my seriously noisy Acer PC silent! If i need a PC fan, I won't use anything else.

If you have a Dell PC don't buy. dell wire the fan connection header different from standard, obviously so that you need to buy a fan from Dell at elevated prices. Look's like a nice bit of kit though, but not for Dell.

Back Story:I have a HTPC that has a small ITX case.. which had a nice low power Haswell Refresh I3 (4170T) in it and a lowish power gfx card (GTX 1030 - only 30 watts TDP).. This was used for casual gaming and media playback of movies etc.I started to get back into gaming after about 5 years away (birth of kids etc), and decided to up my processor and gfx card.. The CPU got upgraded to a Haswell I5 (4790K), and the wattage therefore went up from 35w to 88w.Unfortunately my Scythe Kodati CPU cooler was VERY noisy trying to deal with 88 watts as it was meant for only 65w processors.Solution:The solution was buying this Noctua NF-A9 fan.I took the stock fan off the cooler (an 80mm x 10mm affair), and strapped this to it with some heat resistant rubber bands used for cooking.It increased the height of the cooler from 3.7 to 6cm, but still enough room in my case, as I had a nax height of about 10cm.I then started up the PC with its new fan on the cooler, and et voila! A lot less noisy (Kodati fan was rated as 32db max, this one at 22db max) and actually allowed me to overclock a little bit (200mhz only) due to the extra air flow (from 24 cfm to 46 cfm)!It comes with a great range of stuff in the box too - a splitter, now noise adaptor etc.Very happy with the result!
