NoctuaNF-A20 PWM, Premium Quiet Fan, 4-Pin (200x30mm, Brown)

Great fan if not a little on the pricey side. I bought this to replace the stock 200mm side fan on my Corsair 500r, with both fans at the minimum setting the default Corsair actually moves a little bit more air and kept my graphics cards a few degrees cooler than the Noctua does, but that is the only situation the Corsair fan beat this one. In terms of noise, build quality and air flow (at higher percentages) the Noctua fan wins.The Noctua fan is a bit on the expensive side but comes well packaged and comes with two sets of anti-vibration mounts, screws, an extension cable, y-splitter and a low noise adapter. So when you consider the extras you get in the box as well as the 6 year warranty and excellent build quality Noctua have become known for it's easy to forgive the high price as you are getting a premium item in return.Since there is no standard 200mm fan mounting solution at the moment, this Noctua fan comes with a whole variety of options and you should be able to find a way to mount this fan fairly easily. The rubber corners help to reduce vibration, pair that with the included anti-vibration mounts and you shouldn't have to worry about any vibration rattling around the case.The fan is basically silent all the way up to around 75/80% fan speed and it moves a whole lot of air at that speed, above that the noise starts to increase but isn't as loud of my other case fans when my computer is under load so this is a great fan choice if noise is a concern.

Awesome build quality. Includes screws, plus 2 types of rubbers (see photo), if you dont want to use the screws. Has several hole positions so you can fit is just about anywhere. You will notice that the screw holes seem smaller than the screws and you might think they are the wrong size. Its normal. Just carefully drill into the plastic and the screw will create the space it will need. I suggest you do this BEFORE mounting it, to make it easier to screw them while holding it in the desired position later. The box includes some cables (extension, power, lower fan speed). I used it on a Corsair Graphite 600T SE case. I had to move a drive rack away because this fan is thick and my case didnt have space for that. I didnt need it so i removed it. (see photos). The fan is very quiet and moves a good amount of air. Very pleased. It has a 6 year guarantee. What else do you need?...

Got these fans to replace the standard 200mm fans that comes with the Haf 700 evo case as they were noisy. The Noctua fans are thicker than the standard cooler master fans so I had to get longer screws to fit them, but they fit perfectly into the case despite the thickness. I have to say for a price tag of 499 for the cooler master case you would expect some decent fans. Since installing the Noctua fans I’ve not heard the fans at all and I actually had to check to make sure they were actually turning. These fans are pricey but worth every penny. I’ll give it a few months and review again but I’m confident I’ve found some decent fans for a change.

My existing case fans were rather noisy when idle so I bought this as a replacement. It took a little fiddling and a little trimming to get the fan to fit in my Phanteks Enthoo Pro Mid Tower Case. However it was well worth the effort. I cannot hear the fan in normal use. In high power use any noise is drowned out by the CPU and GPU fans. Delighted with the result.

Quite big fans but zip ties solve the problem. The fans are just amazing, quiet at full speed, great air flow, I use fan control so when pc is not sweating they don't spin, but when they spin they do not bother like previous fans. Talking about looks they not very appealing if you doing RGB build they will stand out, but you can tell from miles away that is Noctua fans, but now I don't care about the looks anymore they performance is beyond looks. They quite expensive but worth it.

The title of the product in my order history is 'Noctua NF-A20 PWM, Premium Quiet Fan, 4-Pin (200x30mm, brown)The images for this product when following the link also show 12v, but I was given a 5v Noctua fan instead.This wasn't the end of the world because there is a 5v USB adapter included with the packaging. I have the cable coming through a piece in the PC case which is removed when pciex16 slot is occupied.The only problem this introduces is that the fan will always be spinning even if you turn off your PC. You will probably have to turn off the PSU switch or just disconnect the fan if you happen to mistakenly get a 5V board.Again no problem for me because this fan is in a headless server.

I'm a bit of a silence freak. I have a passively cooled graphics card (Palit Kalm X 1050ti) and a passively cooled CPU (i8400 with Coolermaster Hyper 612) and I've replaced the fan on my PSU with a quieter on and I have a sound-dampened case with on SSDs...The previous 200mm fan (Antec Big Boy) was ok but I could definitely hear the fan and it, frankly, annoyed me!Enter the Noctua... this fan is connected to my Asus chassis 4 pin port and I've configured the bios to have it in quiet mode. I've not needed to use the supplied "noise reducer"... it's very very quiet.It didn't quite fit in my antec case (there is not standard for 200mm fans sadly) but I was able to make work with the supplied rubber "screws" as they stretch to allow for the mismatch in holes.... basically if you have a 200mm hole in your case and you care about silence, then this could well be the best fan ever invented.

This is a great fan and well worth the investment. Since replacing an old coolermaster fan that came with my case, my temperatures have dropped and my rig is running much more efficiently.The only caveat is I bought this as a top fan for my HAF X and it didn't have enough clearance. I used it as a side fan instead. Just a heads up for anyone who has the same case.
