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

These are worth it! They are fast and cold as ice! The airflow in my case is amazing and I k my have two if these with 3 other Corsair fans, although I am thinking of replacing the other fans with these, I will be ordering one more for sure to install on the top of the tower! Great product and keeps everything cool!

quite a good fan

Best cp fans hands down. You want it quiet? Buy these and low noise adapters. you want your system to be as cool as possible, leave out the lows noise adapters.

Used Noctua fans for `bout six years, these have better cfms and static pressure than my originals. Bought to replace the stock Corsair H115i radiator fans after investigating them.

They move a lot of air. The noise isn’t motor whine or misbalanced blades, but the whoosh of a lot of air moving. Cool things off more than a Noctua 200mm fan it replaced. They get LOUD at high speed, but even at a quieter lower speed they do well. I like to have them set where they really spin up at certain temps so I know things are getting hot before things get too hot.

These are great fans bar none. I was using this to replace the Noctua NF-A14 that is in my Silverstone SG-13. The CPU was running a little too hot, and the case itself was getting too hot because the fan simply couldnt evacuate the heat from the case. This 2000RPM fan is louder but also does the job better. Most importantly it keeps everything inside the case much cooler. The 500RPM jump from 1500 to 2000 doesnt seem like much but it is significant for both airflow and noise, so these are considerations to make when choosing between the traditional Noctua fans and these industrial ones. If you need more airflow, these are highly recommended.

I love this product can use for the fronts or back keeping ur pc clean and ur fans with no restrictions is key to long life span, id sugest these or the https://www.amazon.com/gp/product/B00CP6QLY6/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 for best air flow these brand r worth it make sure all r connected properly

Great fans, keeping my computer cooler than stock fans!

The product arrived promptly. It was packaged very well. I received exactly what I requested and every one of them have worked precisely as expected. I would buy again, when/if the need arises. Thank you.

Great Fan moves a lot of air, high pressure and even at max 2K RPM is pretty darn quiet, you actually need to listen for the fan. WHen I decide to upgrade and I think I will try one of the 3K fans to see if there is a big difference in sound. But someone who wants fan that can move air and is next to silent get these
