Noctua NF-P14s redux-1200 PWM, Quiet Fan, 4-Pin, 1200 RPM (140mm, Grey)

While I was drawn to these fans at first for their affordability and quietness, I have since learned my lesson. Be warned: these fans are a pain to install and a pain to get working. Firstly, the mounting holes on these fans have never been threaded, you have to do this yourself (Which is never detailed to you, might be an industry practice, no idea). This only occurred to me after I found the installation instructions on a forum. There is no manual that comes with the product, and there is no manual for these case fans on the website. Finally, once getting the fans installed, their PWM functions would not operate, no matter how I integrated them into my fan controller. While the fans are quiet running at their base setting, they move almost no air, enough to be outmatched by a single 120mm stock case fan. While this may have just been a fluke on the part of Noctua, both of the 140mm fans I purchased showed the same issues. I would highly recommend that anyone looking to purchase these fans should find a different brand or model for any computer build.

Work very well for getting some good airflow fairly quietly when looks arent the top priority. Unlike some other Noctua fans it comes installed with a longer heavily sleeved pwm wire, not a short wire with a included extension.

These fans are nice and quiet with good airflow as well. Ive had 2 of them now for over 5 years and they are going strong.

Extremely quiet with an incredible air flow. Looks great installed in a black case as well. Included vibration dampners are a nice touch. Typical Noctua perfection. Also box they come in are very high quality and protective.

This is the 4th case that Ive used these fans in and they are so very nice and relievable. I use the grey ones for back and lower air flow and there barely noticeable. As GPUs start to go up in power there is a definite need to pull in cool air from the bottom and most cases dont come with fans.

I was hesitant to buy these, wondering what the catch was. It cant be a noctua fan for this cheap. Yup, they are. Its just as quiet and smooth as the other nocuta fans. They appear to save money on the frame (no rubber corners), accessories (no rubber mounts or silent adapter), and packaging and not the fan itself.

Excellent quality fan. Very quiet, even at full speed.

Read the headline, what more do you need? If you want new fans, you want Noctuas. They move air efficiently and quietly. You can put three of these in a case and can hardly even tell that they are spinning, but they are and boy do they spin good.

Theyre great: quiet and effective, with accurate rotation control.

They are Noctua fans but for a lot less then their top tier fans. Plus they are not the brown/tan color. Super quiet even on max flow cant even hear them over the wifes tower. Bought 3 120mm and 3 140mm and even when I start doing something to cause the temps to rise on the cpu they stay quiet while moving a good amount of air and actually dropped my cpu temp down about 5c.
