Noctua NF-F12 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (120mm, Black)

As advertised, these are industrial fans, built for what Noctua has determined to be challenging cooling climates made for servers. As such, at full power, these fans do sound like a moderately loud jet engine. I bought 6 for my case and my computer now seems like an extremely loud jet engine when I crank my fan controller up to 100%. I do not regret buying these at all however as they move massive amount of air at even the slowest setting. Gaming with these on has been a breeze (more like a hurricane) as I can keep temperatures at a very manageable setting. All of these fans are PWM and have the ability to be controlled through temperature sensors if you should so choose so.

Power and near silence. Replaced some SP120 PWM with these and these are much quieter at full speed. These fans also lowered the temps in my rad loop by 5 degrees. Gotta love em.

If these things spin at over about 950 rpm, which they will, they make a loud whining noise. There’s nothing to indicate on the store page that these are server fans, and are not just a reasonably colored version of noctua’s other fan at the same price point besides a one letter difference in model name. They’ll work if volume isn’t an issue, but be aware that these are not quiet fans.

These fans are great. I can keep my pc cool without hearing them at all or I can turn them up for very low temps while gaming

Under 75% speed you wont hear it in a quiet room 1ft from your face. Above that it makes less noise than most 120mm fans at 25% speed.

I know I installed a fan in the case, I mean I watched myself do it. I was there, I was present when it went in. I see the blades spinning, I can feel the air moving, but I cant hear it, my wife assures me I am not deaf. Fantastic fan.

Best performing fan I have ever seen, but for $25 it should be. Get his model of you are wanting the option of its higher RPM on a CPU cooler or radiator.

silent!

Overall very happy with these fans. the noise level is low and they do their job well. Noctua makes high quality products and these fans are no different.

This thing pushes some serious air! I purchased to replace the stock fan for my EVGA 1080 Hybrid. I have it connected to my motherboard and control it through my fan software. It is fairly loud at full speed, but when youre trying to keep your card cool it needs to move air through the radiator, and this does the job quite well.
