Noctua NF-A6x15 PWM, Premium Quiet Slim Fan, 4-Pin (60x15mm, Brown)

Noctua fans are simply the best. I first used Noctua fans to replace the standard fans on my 3D printer and the difference is AMAZING! They are so quiet you cant even hear them, yet the cooling power is top notch. I used these 6x15 fans to upgrade the basic fans on my BitAxe miners, they keep the miners cooler than ever and they run almost silent. They have been constantly running for over a month now with no issues whatsoever and draw less power. The same with the fans on my 3d printer, they use less voltage (with a buck converter) and have run for hundreds of hours without an issue, the durability is top notch. They also fit easily into place with the anti-vibration mounts - these are simply THE BEST.

Way quieter and much better than the stock fan in my Argon EON NAS. Great fitment, there’s a reason Noctua is considered to be the best.

At first i was hesitant in buying a fan for $15. I caved and bought two for my ender 3 v3 se printer. Used a buck converter for the motherboard fan, my psu fan was 12v so i just needed to make a plug. These come with an extension cable so i cut the end off of that instead of on the fan in case i want to reuse them later. My printer no longer sounds like a server rack. These are incredibly quiet. Way quieter than a brushless fan.

Powerful yet quite little fans. Perfect for ITX cases (Fractal ridge). Do wish a chromax black version existed…

I’m pretty sure this is the only fan you will find at this size that is this silent. I am using in a Fractal Ridge SFF PC and it is excellent. I replaced every fan in the case with Noctua fans and I cannot even hear it anymore when gaming. It used to sound like a jet engine when playing a game. My temps also dropped a good amount. I’ve used Noctua on and off over the years. Sometimes I just want something flashy with RGB and all that. But if noise levels is your priority, nothing comes close. Even the decibel ratings don’t tell the full story, because I get fans rated close or as low, but there’s just something about Noctua engineering that is different. After doing this Fractal Ridge build, I have rediscovered just how superior Noctua fans are.

May these be ugly as sin they quiet and quality. I have used these for decades and will continue todo so

I bought this fan to add active cooling to my cable modem. It's been great. It's fairly quiet even at full speed, and turned down to about 50% speed via a fan controller, I can't hear it at all. It's certainly moving enough air, the modem went from hot to the touch when running to completely cool.

Silence is golden! These are high quality and can’t be beat. Great air flow and the fit my chassis perfectly! There is no better fan than Noctua!!

Finally total silence! i love my NAS again. It had a cheap 2 ball-bearing that would emit high pitched sound, so annoying. danke schoen Noctua!

I own more than 50 Noctua Fans, all sorts of sizes and models... and the collection will keep growing :)

Keeping to noctua standards this is quieter than the stock fan and comes with various cables and mounts for any situation you may come across.

Sempre il top!! Costano care ma valgono tutti i soldi spesi, avevo preso 2 ventoline di altra marca silenziose per risparmiare ma di silenzioso avevano ben poco, sono quindi tornato su quello che si può definire "un nome una garanzia". Fanno il loro lavoro egregiamente e soprattutto in silenzio!!

Very quiet. I bought it to replace my 3D printers chassie fan.
