Noctua NF-A15 HS-PWM chromax.Black.swap, Premium Quiet Fan, 4-Pin (140mm, Black)

I bought this to put together with my actual Noctua fan to go on my air cooler. Around 600-1000 RPM the fan works great without any problems and you cant even hear the fan noise, but as soon as the fan hits that 1100+ RPM there is a loud noise which makes me believe it cant handle high RPM nor Full speed, or it could be I just received a faulty fan..Other than that its a great fan, but I will have to replace it with an actual Noctua fan for my air cooler, such as shame I was looking for different options to buy.

I ordered 3 of these and they are great. 1 fan was clearly used and missing parts. Other than that they are quite and move lots of air.

I swaped out my ugly Noctua fans as I was moving my parts to a new case and wanted a more comprehensive build and couldnt be happier. These fans move alot of air without alot of noise. If you have the money you wont be disappointed in the quality and reliability of the Noctua Chromax series.

Awesome

Used to upgrade a NH-D15S, works great, nice an quiet, and my CPU is cool as a cucumber. Installation was a pain, but that was more due to the stupid clips that the D15 uses, and me using a mid-size tower case.

Took a $90 cooler and made it $150, but kind of worth it, since that brown is hideous. I put two fans on that cooler and get decent thermals for a hot room upstairs. I have it in a push-through config. Where the the intake is one one side and the exhaust is on the other side in line with the airflow of my case. Barely cracking 50C running Cinebench or any other benchmarking test for that matter since I paired it with a giant case as well. They work great, dont really push a lot of air. I have all noctua fans where I can (save GPU and PSU, didnt have control over those fans). And while its really quiet at full blast, its barely pushing 3MPH of wind. My 140mm Industrial is pushing nearly 6MPH and both are technically the same size. Didnt know giong from 2600RPM to 3000RPM was a drastic change like that. OTHER than that it was pretty easy to install. The clips can be finicky, but are secure when on. Helps go with the blackout theme I was going for with this case, even though the heat sink is still very much silver, and theres silver on the Zenith II Extreme Alpha, so its not a total blackout, but good enough. As long as it works and keeps tems down, thats all I care about. And it does do that, well.
