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

After fixing my mistake and receiving the 120mm fans, I got just what I expected from Noctua. These fans work, they dont stop working, they are quiet and powerful and beautiful to me. Brown is the color of us, it is the color of trees, get with the brown life.

Lets get one fact out first. as of this writing, there arent that many options for radiator optimized high static pressure 140mm fans out there.

They performe well and are only loud at max load which it never runs because the temperatures are not that high.

All of my PC builds are designed as positive pressure cases. This is the exhaust fan I chose. It works perfectly.

These are definitely industrial fans. Fast and loud, they move a lot of air. I put these on some corsair AIO radiators in a pull config and the temps are really good. But, the noise is high due to that airflow - just be warned. Not marking them down as they are doing what they were designed to do.

Just as described, arrival was lightning fast.

Best in class fans for airflow (and performance)! Beats anything else in the market. Great for radiators with the high airflow and static pressure. Have 6 of them on my 360mm radiator. Would recommend for those looking for the best of the best.

The fans push a ton of air, more than any fan ive ever owned, but at high RPM made a loud hissing or buzzing sound, I tried different power setups and could not get rid of the buzzing, at lower RPMs there is little to no buzzing but about 1400+ it gets louder and louder until it is louder than the actual fan or air moving through. They are very expensive at 30 bucks a pop and I was expecting more.

Im using these to cool a EK-420CE rad. At 200rpms theyre whisper quiet, and at full 2000rpms theyre loud, but thats expected at full tilt. Still quieter than anything Ive ran at 2K rpms. I did have 1 fan die on the 1st day of use, so I guess well see how Noctuas customer service department works? I have Noctuas in other builds and Ive never had issues but these things happen I guess. Well in any case, being down a fan these still cool off my system. Its cooling a 9900k @5.2Ghz, and Im seeing temps around 85c.

I love Noctua!
