Review: Fits in h500 Case Top Fan Mount, Runs quiet - Pros: -Silent due to pushing good air at low RPMs -comes with an extension and even a low noise adapter to force its max RPM to be lower if needed -Price isn't bad considering the quality Cons: -Very thick which can cause an issue in some cases Awesome quality fan that I have no issues recommending to people if that are in the market for a good quality low noise fan. Side note for fitting in the Cooler Master h500 case: It fits in the top if you remove the rubber bits on the corner (other wise they'll fold due to pushing), then line it up so when you shove it in then it'll basically be where the holes are lol Yes I said shove it in. You have to force it in, but no worries it won't break the case nor the fan. Secure it with screws in the fan box instead of the silicone options. The Case wasn't made to accommodate a 200mm of this thickness, but it will still work. Just make sure you have the fan oriented the right direction ahead of time so you can have enough room to plug it in, though it does come with a nice extension that I did use for tidy cabling purposes. I did not try the front fan section since there are no mounting standards for 200mm fans. Since the top was a very tight squeeze, there was obviously no planning around making Noctua's 200mm fans fit.
Review: Incredible fans! - I had never heard of Noctua until recently and pretty much thought of computer fans as just generic fans. My ignorance was suddenly exposed to me and it seems that Noctua was founded on the principle of "we are going to be Rolls Royce of computer fans". I am looking to build a Corsi Rosenthal box for air filtration. I was going to get a box fan until I read all the reviews saying how loud they are. That quickly took me to the superiority (at the noise level at least) of using computer fans instead, and every review I saw on YouTube either used Noctua fans, or said that the box under review was really good and/or quiet but obviously wasn't as good or quiet as if they had used Noctua fans. With so many references to this company, I started reading up about the company and looking up their fan models. I eventually bought two of their NF-A20 fans. Everything about them is quality - from the packaging, documentation, performance, supplies that come in the box with the fans. Noctua don't stint in trying to provide the customer with the best experience and best fans possible. Are Noctua fans expensive - yes, but you certainly get the quality you pay for. The level of performance engineering in the fan design and attention to detail to prevent vibration and noise while maintaining quality performance is evident in every aspect of their product. I have no yet tested the air flow of the fans but I'll be highly surprised if they don't meet (if not exceed) the documented performance advertised. I don't have a sound meter but these fans are SUPER quiet! I cannot believe that anyone could accuse them of disturbing sleep for example. On the contrary, if you can't actually see the fans turning and aren't in the direct line of the airflow, you can easily wonder if they are even on and working as any ambient noise will totally hide the noise of the fans themselves. HIGHLY RECOMMENDED!

### ⭐⭐⭐⭐⭐ The Fool Buys Lesser Fans Every Build. The Wise Buy Noctua Fans, Once. I Was a Fool.
*by S***Y on January 14, 2020*

- I was sick of a hearing an 300k mile Camry trying to get into 5th sitting under the desk. (That's right, that's where the box belongs, not on top right next to your screen with the design aesthetic of a Tijuana Nightclub.) Noctua fans are QUIET. I CANNOT HEAR MY BOX AT ALL ANYMORE AT IDLE, and even at full RPM they are so much more bearable, and move more air, than any other brand that I have had. Pretty much the quietest case fans on the market. - The build quality is exceptional. Noctua specializes in case fans, and they make them better than anyone. The best bearing setup. The best fin design. The tough plastic. The tightest assembly. Looong Lifespans. - PWM control option for all models. Set the curve, ride the silence, or unleash the fury. - Braided cord, extensions, and y adapter included. Also silicone standoffs and stainless grubs. Nice. - The packaging. You can feel the love these people put into their product just oogling the cardboard it comes in. - I like the look of the dreaded Noctua Beige + Brown. It's pure function over form. Extreme efficiency and utilitarianism.
