NoctuaNF-A20 PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (200x30mm, Black)

Exactly what I needed for my audio video receiver.Large enough to cover most of the top of my AVR, so the planned adapter was not necessary, I just laid in on top over the warm area and plugged it in to a power supply.I had anticipated using a speed control to slow and quiet the fan, and that was un necessary because it was quiet enough at full speed that I have to get close and hold my hand over to feel if it's running. Normal house sounds make it hard to hear unless it's very quiet otherwise.The large diameter slow speed produce a large volume of airflow at low speed, so there is very little if any wind noise. Before the install I set it up vertically on the table and even though the breeze comming off it was soft it would russle a paper napkin 6 ft away. Not a lot of pressure and very little sound. The AVR only gets slightly warm without the fan so with fan, it runs at room temp.I used a load triggered power strip and a 12V power adapter to come on with the AVR. I mistakenly left the fan plugged into the always on outlet and didn't notice it running continuously for 2 days. I bought the black version, and it isn't noticable in my cabinate.Im very satisfied with this setup

Other fans have great designs for airflow and pressure as well. It's not that Noctua necessarily has the best specifications for your application either, since they only have a few fans and the whole fan market has thousands of options.For me, it comes down to the reliability of the fans. I've had to replace a lot of fans from other vendors over the years but Noctua has been the only one that just keeps spinning without extra noise. Even if there is a problem, they have a 6 year warranty, something I've never had to make use of.With the addition of a 200m option from them (in black - really my only complaint is their signature brown fans just don't go with the majority of my case designs), their lineup is pretty complete. As a modder I suppose I wouldn't mind a 160mm fan but I'd use them maybe once a year so I guess they shouldn't listen to me.

The fan I received had a mailing label to a single family home address in Battle Creek, MI. I know this because it had a big Amazon label placed over the shipping label and when I peeled off the Amazon label it was the kind that tries to mask the underlying label with a bunch of voids printed all over it. I used a flashlight from behind to get the information from the shipping label. The product box was not sealed, and the paperwork was missing, but other than that it seemed to be ok. I needed this fan, so I am keeping it. I tested to see if it worked, which it did, so I installed it in my rig. I have no problem with the Fan, it runs silent and pushing air through my rig. I'm just pissed that Amazon sold me a returned item and tried to hide the fact with a silly label. My rating is for the product!

Sucks the hot air out too good. Good price, Strong durability, Cable length small but they provide extension yet it easily unclips, No vibrations as long as you put the cushions on and the speed is just right because it sucks a lot of air.

It's a Noctua fan, you pretty much know what to expect. Very quiet, very well built, and very powerful. Got one to use as a large side fan for my PC tower, cools it down and is a fraction of the volume my old fan produced.

Had my computer case fan rattling for so long. Got this to replace it and it's so nice and quiet that I almost forget I turned on my computer. Worth the price

The fan itself is great. Probably the best 200mm fan (for moving lots of air quietly) you can get here in 2023/2024.It has no RGB feature but that isn't necessarily a bad thing. Still would be nice for this price.It does have 4 sets of colored silicone bumpers to dampen vibration which is a well intentioned but mediocre attempt by Noctua to add some pizazz here.Uses a 4 pin PWM connector so its easy to tune the rpms to get your ideal air movement and noise ratio. This is basically silent (~25dba at 800rpm) at full blast though and produces a very low pitch whoooshing sound that can only be heard up close (around 12in or so).I knocked off a star because of the high price (Noctua's fans are good but the prices...jeeez!), the fan cable is kinda short at 30cm (needs to be nearly doubled IMO, had to use extenders to just reach my mobo in my case, Thermaltake Core X9), and doesn't include longer screws in the kit.You're going to need 35mm+ long screws to mount this fan on many cases. The included M3's won't fit for many 200mm fan mounts. Its a bit thicker than other 200mm fans so watch out for that!There are also 3 sets of mounting holes: 154x154mm, 110x180mm, and 170x170mm.

Bought these for a specific case mod where i needed to eject heat from a gaming PC mounted in a confined near ceiling box. I mounted two of these side by side on what used to be the face of the PC and can I tell you what no issues whatsoever with these fans solving my cooling woes. At first I was thinking that I would need to have some 120mm fans blowing INTO the case and these two fans blowing out of the case to ensure the flow of air needed to cool the 1070 TI and the I7-3770 when getting bench marked. With this push pull setup I found that the CFM pull of one of these fans was equal to nearly 4 of my other 120mm fans.... so what would happen the 120mm fans would be sucked faster than they normally would spin causing excessive fan noise. After removing all the 120mm fans and only having these pull air through the PC all the 120 mm fan noise went away and the cooling was maximized. Oh YA! Ill post a pic of my mod some other time.
