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

this thing moves some air. i have had zero issues with these fans.

it lower the temp of my radiator around 5 degree.

Fan works fine, but it is far more noisy than I would like. Will be replacing soon.

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.

normal

Needs a powerful PWM signal to spin, I cant daisychain the PWM through any other fans, even if Im drawing the power from elsewhere. 5 corsair fans will run off that PWM signal, but I cant run any one of them at the same time as this fan.

I have bought a ton of fans through out the years. This one is well built but and quiet but I have bought cheaper fans that push the same amount of air. I am hoping with the quality and higher price it will last longer. I would recommend this product.

Noctua, its all said

Can be a bit noisy on default settings but it did drop the systems temps by over 10 degrees overall

Strongest fan and quietest fan Ive ever used. One of these puts out enough air to force air out of every grill in my PC case on full speed. However, on full speed, this thing is pretty damn loud. Its probably tons quieter than any other fan that puts out a ton of air at the same RPM, but just worth noting that if you use this above 40%, its going to be loud and your silent PC wont be silent anymore. With that, if a little noise wont bother you, two of these on a 280mm radiator would rule. Theyve got excellent flow and a super high static pressure.
