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

Bought two of these, and had a problem with one of them. I contacted Noctua and within less than a week, the broken fan was replaced with a brand new one.

Great fan, it moves a LOT of air.

Top quality build materials. Superior longevity. Over 7 years and Ive not had a single issue with the 20 or so I have purchased for various builds.

Works as advertised and to its name! Perfect set of fans! Quiet and Powerful! <3

it lower the temp of my radiator around 5 degree.

Pros:

Great Fan moves a lot of air, high pressure and even at max 2K RPM is pretty darn quiet, you actually need to listen for the fan. WHen I decide to upgrade and I think I will try one of the 3K fans to see if there is a big difference in sound. But someone who wants fan that can move air and is next to silent get these

powerful.

Its a fan, it blows air. These are higher RPM fans so they can get loud. At low speeds, they are quiet. Personally, I will deal with a little noise if it means that my system will stay nice and cool when I am doing video conversion, etc.

I kinda struggled in deciding whether to go 2000 or 3000, as there is a mixed review of how much the min rpm of the 3000 could do. I hope my review can help someone out there facing the same decision as me and make a wiser choice. So, I ended up with 2 * A14 2000 and 1 * F12 3000, I connected the 2 * A14 to my corsair H115i and they were quieter than the stock fans at low speed, but at high(1600) to full speed(1700-1900), there is a humming noise (not a consistent kinda noise tat the stock fan produce at high speed) it is indeed lower in dB (note that stock fan max at 2400), but the frequency produced is more irritating than stock fans noise to be really honest, this caused some disappointment for first time experience with Noctua, especially after all the hype I heard about them. Now, the F12 3000s, the stated min rpm is 750+/-20%, but using Asus M8HA MB, Fan Expert 3, after auto calibration, its minimum rpm is 1380. Nothing lower than that can keep the fan ON. Currently do not have another pwm controller on hand to test out if the min rpm of 750 could be achieved, but 1380 a little on the noisy side during idle. So people, get what you need, dont follow my footsteps thinking I could pwm the fans and throttle to any values I prefer between 750 - 3000.
