Excellent product. Quick install, super quiet!

Very good product

Quiet and lot of air flow! Love it

PCs stock fans made it sound like there was a mini tornado in my PC. Thanks to these fans, its now dead quiet, and the only things I can hear now are my ac and tinnitus.

My Corsair 400Q chassis with 2 non-PWM fans was pretty quiet already. I just thought it wouldnt hurt to replace the fan in the front with an NF-A14 PWM to make it even better. Setting up the new fan at the same RPM, the CPU and motherboard temperatures dropped 1-2 degrees right away. Apparently, its pushing more air. However, the Noctua fan was so loud that I had to go back to the original Corsair fan after a day. The quality of the fan is certainly better than those that come with the under $50 cases. But it doesnt really amaze me as I have been working with high quality industrial computers for years. My take is that you should be fine with the NF-A14 PWM if you dont use it as an intake fan and you keep it under 700 RPM. The motor noise at higher speed is really bothersome to me as it is a low frequency humming that sounds like a running refrigerator compressor. To Noctuas credit, their 92mm PWM fans do work better than the stock fans in my Lenovo TS440 server.

This seems to be a great fan for moving air but not nearly as quiet as advertised or expected.

WHAT? I cant hear you over my fan noise.

Ive always used standard fans that come with my case. This time I built my own case so I needed some fans and got Noctuas. I was suprised at the difference in noise. They spin up to full speed, a little loud at boot, then go back down to a speed that is almost totally silent.

Great fan, quiet and easy to install
