Noctua NF-A14 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (140mm, Black)

excellent Fan

After watching video reviews, reading reviews I purchased two of these to replace the fans that came with the A radiator CPU cooler. The stock fans were too loud when editing and working at my desk. These Nactuas went in like they were made for this radiator. It was an easy install for a front panel push configuration. I fired it up and instantly heard the difference. I am a believer now. They really are quiet even at 1310 rpm. I set them at 910 rpm and am very happy with my purchase. Awesome product for performance at a whisper.

Nothing bad to say about these fans. RPMs are a little high but thats nothing some fan control software or controller cant fix. Great air flow, very low noise, over all just a great product.Love the black fans, not a huge fan of the dark brown rubber corner pieces but they make all different colored ones now so thats a non issue. Noctua are the best fans IMO and the fact that you can get black ones makes it a no brainer. The only concern before was the color for some people but you cannot be Noctuas quality. Highest marks for Nocuta for making these fans.

Running Right now on custom settings. Very good fan for its price, not to mention the warrantee.

Purchased two for my NH-U14S cooler. Noctua customer service (Emanuel) was incredibly helpful and immediately shipped new 140mm fan clips for it free of charge.

These are definitely industrial fans. Fast and loud, they move a lot of air. I put these on some corsair AIO radiators in a pull config and the temps are really good. But, the noise is high due to that airflow - just be warned. Not marking them down as they are doing what they were designed to do.

Fans are of good quality and Value for the money. Fans do not slow down, even when using PWM function in Bios 1200 lowest they go and have lots of wind noise fans do not run slow enough to hear any bearing noise or rattling just air noise..

The people here reviewing this fan that say its too loud are using it improperly or they dont have any kind of PWM fan support. Yes, if you run the fan at 2000 rpm its going to produce noise, any fan will produce noise pretty much above 1500 rpm no matter what. These fans are rated at 2000rpm and the noise level of 31dB, but thats only at 2000rpm. These fans can drop way down in rpm, its not like Noctua is forcing everyone to run these fans at 100% all day long.

I use two of these fans on my custom water-cooling loop radiator. At 700-800 RPM they are barely audible and I can cool my OC 6600k and 980Ti to about 9 degrees over ambient temp. They will go down to about 250RPM before stalling but really dont move any air at that speed.

As everything Noctua (In my personal experience, anyways) these fans are great. I bought 4 of these to use as exhaust on my Core x9 case, and they are incredibly silent. Havent got the Core x9 just yet, so I have them installed on the HAF 922 it will be replacing. I have my motherboard controlling the speed of the fans, and at 1500rpm, they are quieter than the NF-A15 (the 1500rpm version included with NH-D15) running at 100%. So I guess the Three-phase motor tech really pays off, since it is not as noticeable as a fan that was silent already. Now the other fan is annoying me. So, I want to get a few more to remove the two NF-A15s I have in my computer.
