Review: Amazing! The Real Deal - 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 120mm Out 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.
Review: Best of the best. - I wanted to replace my stock NZXT case fans and Corsair fans that I bought. My research ended up leading me to this Australian brand with the fugliest color scheme. But when you are in for serious performance, Noctua will definitely not disappoint. Pros: -Silent. These are silent killers. You can barely hear these things spin even on max speed. With headphones on you definitely won't hear squat. -High performance. These bad boys are almost the best in terms of performance compared to any other fans out there on the markets. Tons of reviews will support Noctua. -Good build quality. You can feel the difference in material used to make these fans. They are a lot sturdier and do not wobble around. They also put rubber around the screw holes to prevent and vibration against the case, adding to the low noise. -Warranty. You get lifetime warranty with Noctua. Their customer service is excellent. I bought their tower cooler and emailed to ask if they could provide another fan bracket so I can attach another set of fans on it. They obliged and mailed the brackets free of charge to my place. -Peripherals. They give you several extra cables and anti-vibration "screws. They definitely go well and beyond to ensure your desktop is chilled and quiet. Cons: -Colors. Granted this is probably a marketing ploy to make their product stand out with their brown and poo-brown colors. Their marketing strategy is probably to prove that their products are superior and don't need to look cool or gamer-ish to attract customers. It definitely works, because any informed gamer will recognize their products instantly. But honestly at this point it would be GREAT if they had more appropriate colors. -Price. With great performance comes great expense. These fans are not cheap. I spent well over $140 buying Noctua case fans. But they are definitely genuine premium products. Conclusion: You won't regret the purchase if you understand that these are premium products. Their price is truly justified, but if you really don't want to spend that much you should look elsewhere (if you are okay sacrificing some performance and noise). For me, I've had all but great experience and became a die-hard (at times blinded) Noctua fan (pun intended). But yes, they need better colors.

### ⭐⭐⭐⭐⭐ High quality, super quiet, long warranty, perfect for my application.
*by E***R on August 4, 2026*

I replaced the cheap computer fan on my Novakool fridge in the camper. This fan is so quiet that I have to sense the airflow with my face! Exactly what I wanted. The configurable fan speed is a plus. And the six year warranty tells me it's well made and I won't have to pull the fridge any time soon to replace it. Great fan!
