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

This absolute bohemith of a fan works quietly, but pushes an astronomical amount of air through. The build quality is amazing (as expected) since its a Noctua product. I expect this bad boy to run for a long time, currently using it on one of my servers.

You cannot put the front cover of a thermal take view 51 without modification.

Very 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.

I bought this fan to replace a failing Cooler Master A20030-10CB fan that was mounted to the top of my Cooler Master HAF 922 case. It turns out the presence of 170mm mounting points on this fan prevent it from fitting into this particular case, which uses 154mm hole spacing. I did not know this before I bought the fan. Nothing some marking and quick Dremeling couldnt solve, though! Now that the fan is in the case I love it. Almost silent and moves a lot of air. Huge improvement over the fan I removed, although that one was 8 years old. Well see how this one holds up.

Look no further for fans, its so quiet I had to keep looking to see if it was on

This fan is nice. You dont know it yet, but it is. One of the nicest things is the mounting points on the fan. I have two Cooler Master HAF XB EVOs, they take a 200mm fan in the top plate. Not just any fan, but one with the holes in a strange rectangular configuration. This fan has that. That is a rarity you may not realize. It adds value here, now and in the future.

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.

This is a very nice product. Its well made and is very quiet. Please know that its 30 mm thick. Thats the norm for 200 mm fans. If you have the clearance this will quietly do the job while looking good.

Well, I had been holding off ordering this fan mostly because the rest of my case uses the REDUX gray Noctua fans and I was hoping Noctua would release a 200mm REDUX. I waited nearly two years and then finally my very old 200mm XIGMATEK case fan started to slow down so I had no choice. I installed this fan a couple days ago and I must say I was expecting a great fan, but this exceeded my expectations dramatically. It is so solidly built compared to the XIGMATEK; the Noctua must weigh 3x more at least. Also, the motor is very large, and the bearing has zero play. The fan blades themselves are thick and sturdy. This is Noctua at its finest.

For my 1st custom build (of which there are more to come), going big on Noctua was the right decision.
