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

These fans were nothing but disappointment to me. I was told that Noctua Made QUIET fans but it appears I was wrong. These fans were Loud compared to my Case fans. The only reason I gave it two stars is because it did give good airflow in my 750D case. but other than that the fans for bad for cost and silence.

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.

Great, quiet fan. Great when used on a radiator.

Im using these to cool a EK-420CE rad. At 200rpms theyre whisper quiet, and at full 2000rpms theyre loud, but thats expected at full tilt. Still quieter than anything Ive ran at 2K rpms. I did have 1 fan die on the 1st day of use, so I guess well see how Noctuas customer service department works? I have Noctuas in other builds and Ive never had issues but these things happen I guess. Well in any case, being down a fan these still cool off my system. Its cooling a 9900k @5.2Ghz, and Im seeing temps around 85c.

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.

Best in class! Cant get no better product to move airflow w high static pressure out there. Worth every penny they cost!

Noctua fans are great.

The only industrial thing about these is the sound, theyre loud at higher RPMS. The seem to be great and have a very high static pressure but just too loud. Im basing my opinion on a comparison i did with three other fans i had and this is by far the loudest. Very solid part but just not good for a silent.

Had an even higher static pressure than I expected, and is the quietest fan in the case.

great item
