The build quality is top notch and they bundle accessories for just about any use case/situation. They include screws and rubber push pins depending on how you want to mount them, I personally prefer the rubber mounts for ease of install and quick removal if I ever need to, but depending on accessibility you may want to use the screws, the only downside is that the screws are silver so they may be a little bit of an eye sore if they are visible and you have a different color case. They also include a Y splitter if you want to connect 2 fans to 1 header and a resistor cable if you want to bring the noise level down even more (They are super quiet right out of the box as is), as well as an extension cable to get to further headers, the stock cable coming off the fan is only about 6" long so you will most likely need to use it if you are trying to get some nice cable management. I have also used these fans for almost 8 years at this point and I haven't had a single issue with any of them, other brand fans I have used that use a different bearing method usually will start to wobble/grind after a couple of years, typically right out of the warranty period go figure, after switching to Noctua I won't go back to any other brand. If you are looking for a Noctua to match a black case/if you are not a fan of the color scheme (although I think it will grow on you after a little while, I love the look now) they sell an Industrial version that is black but admittedly are slightly louder. 10/10 fans, look no further! ### ⭐⭐⭐⭐⭐ Amazing! The Real Deal *by N***R on Reviewed in the United States on January 15, 2020* UPDATE:these two 120mm beasts are still running just as good as the day I put them in. I wanted to include some specification information I learned after spending the better part of my day combing through the specs on noctua’s site. They provide a wide range of specs for these fans and it’s helpful because they make several versions of each size. Each version mainly consisting of different fan blade, size, shape and number of blades. Noctua provides a very wide and comprehensive amount of data for each fan variant.My first conclusion is that the 120mm fan line is by far noctua’s most efficient in power consumption and cfm output at a given power draw. Also the 120mm line is generally the quietest line of fans when compared to the cfm output. 120mm seems to be a sweet spot for the range of fan sizes noctua makes. I had considered gettin 140mm fans for my next build but after learning what I have. I’m sticking to 120mmOut of the 120mm line up the NF-S12 series moves more air by a wide margin. It generally blows away every other version and even beats out the larger size fans. The only place this fan was slightly beat out was in sustained air pressure.Basically this fan had slightly lower numbers in sustained air pressure output because of the aggressive angle of attack these blades have but generally unless you are placing this fan rite up against a very restrictive air flow environment like say a densely packed set of fins for a cpu cooler. The slight air pressure deficiency won’t ever become an issue. Keep in mind that it wouldn’t even become a factor unless the fan began to build air pressure in its operating environment. Something that shouldn’t happen with case cooling fans if you are doing it rite. Matter of fact. Noctua uses the higher air pressure output variant fans on there line of coolers. So, perfect example of how knowing your specs and operating environment can enable you to engineer a damn near perfect air flow profile for a given need/situation/preference.ORIGINAL REVIEW:NF-S12A FLX - is the fan I ordered and before I ever installed it. I hooked it to a 12.5v constant power source and spun it up in free air at full power. NOT A DAMN SOUND! Completely silent. A mouse fart would have broke the silence. On top of that. The cfm output is astonishing. Just keep in mind. The fan may be silent but what it pushes air through or past can still create noise. Think strategically. I had two silenX fans go bad after about 13 years in a old rig I use for basic stuff ( the one pictured ) so I figured I’d try these out as a test for my new rig I’m currently planning out. I was blown away by the amount of air flow in and out of the case. Again, the fan may be silent but if the case is not conducive to smooth air flow, you can still experience noise. So using the limiting adapters may be a good idea if you experience this.Case and point. These are the best fans I’ve used or experienced in my life. Combine that with a VERY aggressive angle of attack from the blades, which is difficult to sustain airflow and keep unwanted volumes down. You can see on the fan blades and inside the fan housing. The little dips and dimples added to counteract the negative effects of that given aggressive blade angle and speed. The engineering and time that went into making these the best fans on the market. that is what elevated them to the amazing status in my book. You know the technical details.Just do your research. Study the specs and with a little forethought. You can get all the cooling muscle you want and need and keep everything super quiet at the same time. ### ⭐⭐⭐⭐⭐ Whisper quiet & powerful! *by J***R on Reviewed in the United States on September 7, 2022* I'm using this fan in a pretty non-traditional manner as an exhaust fan for my composting toilet. The fan must run silently, 24/7, and be able to pull air through a 3"x6' duct. This fan performs admirably. I hooked it up to a simple, two-prong "DC Motor PWM Speed Controller" and it's perfect! I can adjust the speed easily and don't notice any off-effects. It's then wired directly to a 12v battery bank.As previously mentioned, this fan runs 24/7 and is just a few feet away from my bed. With the PWM controller, I am able to drop the fan way down so that the noise is *barely* above ambient. If I need extra exhaust, I can crank it up to max and it still runs whisper quietly - much softer than any other exhaust fan I've used. And at any power level, it pulls enough air to keep the composting toilet vented & dry.It comes with a good handful of electrical adapters as well. I could cut up one of the adapters to attach to the PWM controller without destroying the hardwired connectors into the fan.
