Noctua NF-A12x25 PWM Fan

I gotta say now that I've got a a few of these I'm pretty blown away. They're significantly quieter than NF-F12s at the same rpm while at the same time they make more mid-high freq sound which I can tolerate more of.

I can't explain to people, I didn't saw this from GT period. Except this fans are on 100-200RPM higher speed same noise as GT on 1850 RPM.
Amazing fans, easy to tune with Software like AI Suit or BIOS, high recommendation.
It's bad that complains about price are from people who have 5 different fans in house and serve them for nothing.
I'm more for better and more expensive only.
And I must say these fans have nothing with previous Noctua fans except great package and color, performance are completely something new.

I need 3 more except these 3 I have.

the NB-eloop B12-3 or B12-PS would have been much better comparisons. the B12-4 is a 2400rpm fan and is not meant to be moving this slow. from my experience, slowing down crazy fast, non-PWM fans to 1/4, 1/2 or 5/8 speed (as seen here) never yielded good results in regards to noise. you have to get the right fan for the job.

I know, but I tested those other two fans elsewhere (my website) so couldn't just bring that over here as well. I hear that Blacknoise is coming out with new fans this year though, so maybe they will be a better fit for testing on TPU.
 
When black version become available.
I need 3 more anyway urgently, if I find discount as previous 3 I will use normal. Or maybe I will try Black version.
I'm seriously disappointed because only Chromax color scheme will become available.
NF-A12x25 PWM in Redux color scheme could be most beautiful and best performing PC fan.

These vibration rubbers should be removed from one side depend of fan orientation. No need to stay like this.

Why? I wouldn't mind to have them on both sides when using with a radiator.

Not everyone uses them with rads. And even if they do, people typically don’t put the fans between the rad and the case.

Without the rubber dampers, it actually does look better. But I’m too lazy to take this apart and premthem off.

That explains the dust build-up on the fan blades especially the top ones. Pretty soon you'll transform them into Redux grey

This was taken when I was cleaning it, which I rarely get to do. That’s why the GPU is not in the pic. This computer is running 24/7, and it’s always sucking in dust. I edit photos and render 3D models on it 8-10 hours a day. And when I’m not using it, one of 3 other people remote into it via teamviewer and do the same. This work horse is always working.

Having said that, I’m glad I swapped out my fans for these noctuas. I can work in absolute silence, even when my computer goes balls to the wall on all 16 cores + GPU and sucks up 700w from the outlet.

Well, me and many people I know has the intake rad as push, not as pull like in your picture.

But yeah, I guess it would be ok that the dampeners just would be in the box and the end-user just installs them as (s)he would like.
 
How much you set RPM on NF-A12x25 PWM on radiators.
On mine 60% up to 55C.

I removed rubber, only gasket is on side close to radiator. Rubber is useless in this situation.

the 15mm version is now available in chromax, but at an even higher price premium than usual: https://www.amazon.com/dp/B0813X9G8T/

i don't understand why they made the smaller version in chromax first. it's a niche product. i have two of the 15mm versions of this fan myself in my VR rig, but i still think it was stupid to make the less in demand product first. the only logical explanation is that they aren't confident in the new material and wanted to launch the less used version to reduce exposure to mass RMAs.
