Noctua NF-A14 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

Id recommend to anyone wanting a fan than reeks with quality.

I purchased 2 of the 140mm fans (NF-A14 PWM) to replace 2 Akasa Viper 140mm fans I was using on my 280mm AIO. Not only are these WAY quarter (even though they are only 100rpm slower than the Vipers at max speed, which is what I run all of my fans at 24/7), they work noticeably better. My coolest core was basically the same temp at idle, but 2 of the others went down ~3-4 degrees, and the hottest was done 1-2 degrees. Load temps are at least 5 degrees better.

NICE cooler

Installed in a micro-ITX case where cooling is really important due to the compactness. These perform great and are often so quite I cant tell they are on. Installing with the rubber pins to dampen vibrations is easy and a nice touch to include. They also come with a Y-splitter and 2 different extension cables.

I bought these to replace the fans on a Corsair H110 cooler (had the dreaded and common rattling fans issue). Everything about these fans feels solid. Rubberized corners for noise dampening, both soft and standard screws, adapter cables for different operating modes, and most importantly, they are appropriately quiet. I hear the air moving / blades spinning but there is no obnoxious pitched hum that some fans make.

I tried buying other fans to save a couple dollars, but that only helped me appreciate the value Noctua brings. Solid construction, great performance at every RPM, much quieter than other fans, and comes with useful good quality Y-spliters, extension cable and silicon mounting. I dont even consider these fans to be expensive because theyre worth every cent

Best thing ever happened to your choky air-tight h400i matx case.

Very good case fan. Good Airflow with little noise. They are a bit on the pricey side but they come with alot of extras. (Adapters, Mounting Hardware, extensions...) Overall, they are well worth their price. Would definately buy again. Have this installed in a LIan-Li ITX case.

My computer runs idle at 300 RPM and I cannot hear 3 of these fans even when my ear is pressed to the case. they only start to become audible around 500 RPM and stay pretty quiet even as they hit their max 1500 RPM.

Work as expected.
