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

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.

This fan is great. I have two of them in my case and it has lowered the temp about 2-4 degrees F. Not bad.

Amazing fans. Absolutely no complaints. very quiet. Reccomend keeping them at around 1500 rpm. Great results with low noise at this speed.

Noctua fans are great.

used these on my computer AIO cooler in place of the loud fans that came stock. These fans have a way higher static PSI and are much Quieter than the stock fans

quite a good fan

QC issues. Noctua will replace bad fans without a question. They need to be worn in a bit before they get a bit quieter. Great performance. Ugly (but you can change that). Crazy strong frame

No LEDs but the best fans I have used so far in my 25 years with building systems. I would recommend these to anyone who wants quality verses pretty lights.

I use two of these fans on my custom water-cooling loop radiator. At 700-800 RPM they are barely audible and I can cool my OC 6600k and 980Ti to about 9 degrees over ambient temp. They will go down to about 250RPM before stalling but really dont move any air at that speed.

Get a little louder than I expected for Noctua but over all great fans, no complaints other than they did not work with a fan controller I got that only had 2 pins for each fan header. Not sure if 4 pin into 2 pin is a nonbo for 4 pin fans but just beware and make sure you research your fan controllers if youre going to use them with these fans.
