Description

Noctua's premium cooling components are internationally renowned for their superb quietness, exceptional performance and quality. The classic NF-B9 is a long-standing favourite among enthusiast users around the world and helped to found Noctua’s reputation as a top-tier manufacturer of premium quality quiet cooling components. The new redux edition reissues this award-winning model in a streamlined, accessibly priced package that has been reduced to the essential core: the NF-B9 premium fan. Its industry grade SSO-Bearing and over 150.000 hours MTBF rating make the NF-B9 redux a proven premium choice that provides trusted Noctua quality. The 1600rpm PWM version features Noctua’s proprietary NE-FD1 PWM IC for automatic speed control, which allows to strike a perfect balance between high cooling capacity and low noise operation in each given situation. Tens of thousands of quiet cooling enthusiasts around the globe swear by Noctua's classic NF-B9. Thanks to its impressive quietness, excellent performance and impeccable quality, the NF-B9 has become an established reference for quiet 92mm fans. Noctua's signature Vortex-Control Notches split up trailing edge vortices and thus spread the fan's noise emission over a wider range of frequencies. This measure makes the fan sound more pleasant to the human ear. Combining the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua's time-tested technology has become synonymous with supremely quiet operation and exceptional long-term stability. Reducing critical rotor stator interaction, Bevelled Blade Tips permit to combine extended leading edges and a higher blade surface area with quieter operation and thus form a cornerstone of the fan's outstanding efficiency. The redux product line reissues some of Noctua's most popular, award-winning models by presenting them in streamlined, accessibly priced packages. All redux edition products are industry proven, time-tested models.

I love these fans!
This is the first time I replaced my stock fans that came with the Intel NUC 11 Extreme. The stock 92 mm fans were sleeve bearing fans, which was set in a horizontal position. Only after a 1 month of use they started to make a clicking/ ticking sound. A google search taught me that regular sleeve fans cannot work in horizontal position as the lubrication is all settling on the bottom. SSO bearings or ball bearing fans are needed to work in the non-vertical orientation. And after installing these fans to the case, the PC became dead silent. Even when under load. I love that they are rated at a much much higher MTTF then the stock sleeve type. I am pretty sure these are the last fan upgrade I would need for the remainder of the life of my PC. ... show more

I'm a FAN of noctua
Review Image by Michael L
My second hand Acer Predator came to me without ANY chassis fans so it wound up getting pretty toasty inside. Slapping this guy in the back made all the difference in the world, and with no noticable added noise. I'd replace my PSU and GPU fans with noctua ones if I could, as those are the loudest components in my tower. ... show more

Awesomely quiet fan
I set out to make a "nearly" silent PC, in that I didn't want to go fanless, but I wanted it to have the fans running so slowly (or off) during normal operation that it was silent, and it was only during intensive activities that the fans would ramp up. Through that process I ended up using 5 different fan models from 3 different companies and the NF-Bx line from Noctua are my favorite and the best value. The NF-Ax series fans are slightly better, but not so much more so to justify the 50% (or so) increase in cost unless you need the vibration free mounting hardware it comes with. Some cost saving advice: don't buy a Noctua CPU cooler. Buy a Cooler Master CPU cooler (I went with the Hyper T2 as it is the biggest one that fits in a standard case) and take off the Cooler Master fan and buy one of these. For ~$27 combined you get what Noctua wants to charge $60 for. The Cooler Master fan sucks and doesn't allow you to reduce the fan speed below ~30%, so it needs to be replaced if you want to go silent, but the Noctua NF-B9 is exactly the same size fan and it is easy to replace it once you realize you can pull off the rubber pads that obscure the fan screws. Another learning, don't trust that the fan controller on your motherboard is doing everything as it should. First, I had to go into bios and change it to PWM mode as it assumed DC mode for the system fans even though it comes with 4-pin fan headers (DC mode doesn't allow it to spin at nearly as low of a speed). Next, it appeared when I was first testing this fan that the lowest it could go in PWM mode is 13% based on the RPM data the motherboard was providing. But then I noticed the fan was still spinning when I put the PWM at 10%, so I figured the fan wasn't providing good RPM data below 13%. Next I noticed it would stop spinning below 10%, so I assumed that was the lowest the fan would go. Not so on either count! I later hooked up the fan to my GPU and it could both spin the fan and read its speed as low as 5% PWM. So apparently my motherboard has it's limits that it won't go below. For all I know, the fan could go even lower than 5%, but that's the best the GPU fan controller will do. (Luckily, even 13% is slow enough to be silent in almost all scenarios.) But the long and short of it, is that with 4 of these fans (CPU, 2x on GPU and 1 on the rear of the case) and leaving the front of the case fan off unless the system gets hot (trying to save a few bucks and not replace the 12" fan unless I need to) as well as an EVGA gold power supply in "eco mode" I have a truly silent PC, where a pretty sensitive dB meter can not detect it being on. I have to do the test in the middle of the night, because even cars going by outside are detectable. But at 3 AM, it reads 21.1 dB with the PC off and 21.1 dB with it on. My stomach gurgles and the stupid thing goes up to 24 dB or I click the mouse and it goes up to over 30 dB so trust me when I say the dB meter is sensitive enough to detect pretty small readings. To be fair and give a caveat, to keep it silent, the fans are running at 13% on the rear of the case, 10% on the CPU and 5% on the GPU. But that's just enough air flow with the good heatsinks that in normal operation the system temp stays around 40 and both the CPU temp and GPU temps stay in the mid 50's.

It's NOCTUA. No needs for introduction.

They are cooling a janky setup I call a "NAS" =) Do it flawlessly, silently and effectively. What else can someone ask from a cooler? A smaller price? Well if it comes with worse noise/performance ratio - we don't need it.

Works great on older PC cases
I was rebuilding an older PC case and needed a 92MM rear fan, since a lot of older cases can't fit a 120MM fan in the rear fan spot. And this fan was just what I needed. I'm really glad to see that Noctua has a Redux line of fans for older cases. And with this fan having a 4 pin connector, it has all of the wires needed to connect to modern motherboards. A lot of people like older PC cases and when rebuilding one, you can get the correct fans for it from Noctua. ... show more

Super silent fan!
This fan was a great replacement for the noisy one that was in an older microATX case for a retro Windows XP computer I was building. Also, the four pin fans work just fine with three-pin fan connectors.

Works as advertised.
I’ve been using this fan for months now and it’s holding up! Quiet, not week like some other fans that I would purchase. Good price as well!
