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

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

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..

Quiet and powerfull. It is a lot for a fan and they never go on sale. I run these on a h100i cpu cooler and clocked it up 1ghz per core for a whopping 56C temp during a benchmark and the fans never hit top speed.

Used Noctua fans for `bout six years, these have better cfms and static pressure than my originals. Bought to replace the stock Corsair H115i radiator fans after investigating them.

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.

The product met my expectations

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.

Replaced the fans on my EVGA liquid cooler and boy can I tell the difference. These fans are virutally completely silent. My PC case has been open for a while and I hear nothing until my system ramps up (and even ramped up the noise level is still low). The build quality is immaculate. The EVGA fans had a slight wobble as the spun around which is nothing alarming but the NF-A14s are so sturdy the there is absolutely no wobble which has to improve its efficiency. These fans move an unbelievable amount of air which will definitely improve the cooling of any system. There is a premium you have to pay for Noctuas fans but with the results I have seen Noctua fans will be the only fans I use in my PC from this point on. Job well done Noctua... job well done.

Very quiet, undervolts phenomenally well, great performance (airflow and static pressure), probably the best computer fan bearing in existence.

Excellent cooling. Speed my tempos by 5c on inflected. Speed load from 76c to 71c,and this is just a charmingly simple fan swap.
