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

Set and forget at 700 rpm, at that speed these fans are dead silent, if you go higher they become a little loud.

It is a little expensive (as most Noctua fans are), but it is well worth it. I had a lot of trouble finding a similarly sized fan with PWM control, and I know this fan will outlive my computer so I can reuse it again for my next build. It moves a good amount of air and is completely silent, plus you can adjust the flow as needed with the PWM control. Very high quality, but then... would you expect anything else from Noctua?

This product comes with less than 12 of wiring to extend to and hook it up to your motherboard. In my case that was not near enough to reach the plugin port. It sits in my PC unused and worthless.

As most case fan, 3d printer, pc builders, ect... enthusiast know, Noctua makes absolutely incredible fans. I can confirm that, they do in fact make INCREDIBLE fans.

Fan spins and is quiet. One of the few that fits a haf xb evo

Helps 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.

This review is for the Noctua NF-A20 PWM chromax.Black.swap, Premium Quiet Fan

I own several noctula fans and never have had one fail. Some have been spinning for 7 years, my PC is usually on unless there a power failure. I cant speak the same way for other brands such as aerocool. The only thing I would have liked would be a slightly longer cable. Its needed in my setup since its mounted on the case door. You can buy extensions for your specific setup.

Replaced my TT 200MM case fans and bought these to match the other noctua products. Its quiet at max rpm of 800 and you can feel that it is pulling/pushing a lot of air through.

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.
