> 3 dayBought 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.

> 3 dayHelps keep the temps down. I have a desk with my PC build into it and once I got an rtx 3060 ti it just wasnt staying cool enough. This helps but I wish it had the ability to spin just a bit more.

> 3 dayVery quiet, easy to install and just enough rpm’s to do a good job pulling the hot air out of my computer case with out sounding like it’s going to take off. Second Noctua fan I’ve purchased.

> 3 dayI purchase a lot of Noctua fans for building high-end computers, so wanted to try these out. On the plus side, they are silent and come with the necessary black sound/vibration pads. On the minus side, they move a bit less air than I had expected (perhaps I am just too used to the industrial line) and the price is a bit too high. There are cases where this would be great and I can say that these are better quality than many fans of a similar size. Buy these if you need a fan of this size, but note that a couple Noctua industrial 140 fans will move more air if that is what you are looking for.

> 3 dayGood job Noctua.
Having received dozens of awards and recommendations from international hardware websites and magazines, the NF-A20 has established itself as a default choice when it comes to premium-quality 200mm fans. The chromax.black.swap edition combines the NF-A20’s signature quiet cooling performance with an attractive all-black design and a bundle of swappable red, white, blue, green, yellow and black anti-vibration pads that allow the colour-customisation of the fan to match individual build colour schemes. For further customisation, a wide range of accessories such as coloured cables and anti-vibration mounts are available separately. Topped off with Noctua’s trusted premium-grade SSO2 bearing and more than 150,000 hours MTTF, the NF-A20 PWM chromax.black.swap is the perfect choice for all users who value individual, focused build aesthetics just as much as class-leading quality and performance.
Award-winning Noctua quality in 20cm size
While more and more PC cases support 20cm intake, side-panel or exhaust fans, many of the bundled stock units and available aftermarket options are of questionable quality. By contrast, the NF-A20 is a true premium grade solution worthy of Noctua’s award-winning A-series.
Please Note: The NF-A20 has a 200mm diameter (7.8 inches), and a thickness of 30mm (1.18 inches). Please make sure you have sufficient space in your case.

Swappable anti-vibration pads in 6 coloursWhile more and more PC cases support 20cm intake, side-panel or exhaust fans, many of the bundled stock units and available aftermarket options are of questionable quality. By contrast, the NF-A20 is a true premium grade solution worthy of Noctua’s award-winning A-series. |
SSO2 bearingThe NF-A20 features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
154mm, 110x180mm and 170mm hole spacingIn order to ensure broad compatibility with today’s PC cases, the NF-A20 features three sets of mounting holes: While the 154x154mm and 110x180mm spacing allow it to replace most 200mm fans, the 170x170mm spacing is used by many 230 and 250mm fans, which can thus also be replaced by the NF-A20. |
Optional coloured cablesNoctua’s chromax line fans use a modular cabling system and come pre-fitted with a fully sleeved black NA-EC1 30cm cable. For refined colour coordination, white, red, blue, green and yellow 30cm NA-EC1 cables plus corresponding NA-YC1 y-cables are available separately. |
Maximising colour choices, Noctua’s chromax.black.swap edition fans can be colour-customised using the included swappable anti-vibration pads as well as optional anti-vibration mounts and cables. This makes them ideal for enthusiasts looking for true premium-grade fans that can be colour-coordinated with popular build themes such as all black, black & white or black & red.
