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

Quiet, lovely, keeps my computer nice and cool. Replaced 5 fans with these.

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.

What a great fan. It has plenty of pressure and cooling capacity. It will outperform almost any fan at any given speed. Yes, its quiet too.

When I received my fans one of the boxes had greasy finger prints on it and the box looked like it was opened. I removed the fan and it was missing three of the vibration dampeners on one side. I informed Amazon of the discrepancy and had no problem replacing the fan. I would recommend these fans. I put two of these on my NZXT AIO water cooler and they do an excellent job.

Replaced the stock 140mm Corsair H115i radiator cooling fans because one was going out. The Noctua fans are quieter and provide better air flow, bringing my temps down about 2 - 5 cel. I would highly recommend replacing any stock CPU fans with this brand/model (make sure you get the right size fan for your computer). Overall I am very please with the performance, I just wish I installed these fans when I originally built the computer.

The product met my expectations

These fans really SUCK! the air directly outta my case! I will nvr use any other fans in my builds ;)

I used these fans for the first time as replacements for the stock fans of the corsair hydro series water cooler. These fans are dead quiet, move the air, and are in a word SUPERB! If not the best fans out there they are darn close.
