The Noctua NH-U12A CPU Cooler Review: Big Performance in a Small Space

Testing Results, Low Fan Speed (7 Volts)
Switching things up a bit, let's next take a look at cooler performance with the NH-U12A fans taken down to 7 Volts.
| Core Temperature, Constant Thermal Load (Low Fan Speed) |
With the speed of its fans reduced down to 800 RPM, the NH-U12A becomes virtually inaudible to a user that sits one meter away from it. The thermal performance still comes close to 140 mm coolers, with the NH-U12A being unable to match it but landing near them, all while outperforming most other similarly-sized cooling solutions.
A closer look at the charts reveals that the NH-U12A actually is rather efficient with the handling of very heavy thermal loads even with reduced airflow. This suggests that the cooler will be able to handle overclocked processors without the thermal control of the motherboard having to shoot the speed of the fans too high, maintaining low noise levels.

What was the RPM on the fans ?Did they manage to spin at their rated 2000rpm during the testing ?

https://images.anandtech.com/graphs/graph14621/111...We reached 1920 RPM, which is well within the manufacturer's margin of error for the fans.

This stupid cooler is way overpriced and outdated. Nickel does not transfer heat better than copper. Why 2 fans? They’re only mere 2 inches apart, why not slap another 2 fans on it? Why Noctua always like to make heavy and big coolers? I’ll never support self-proclaimed “engineers” who has no clues about how to make better products.Korguz - Friday, July 12, 2019 - link
ok sonny73n if you think you can design something better for less.. then go do it...D@ Br@b($)! - Saturday, July 13, 2019 - link
He doesn't have to. There are already coolers with similar performance for less money.keyserr - Friday, July 12, 2019 - link
I would like a section for performance @ normalised sound, maybe at 32db, 33db, 34db etc because 7volts gives different rpms and noise.Arbie - Friday, July 12, 2019 - link
Scythe Mugen 5 for me too. When I last found comparisons of this against eg Noctua it offered equivalent results for much less money, and has been working great for me.But I'll probably just go with the Wraith cooler that will come with a top Ryzen 3000 chip. That does depend on 3950X tests when they surface, but current indications are that better cooling won't increase clocks.
This new AMD lineup will go a long way towards making high-end air - and of course any water loops - unnecessary. Those vendors must be getting nervous.

" This new AMD lineup will go a long way towards making high-end air - and of course any water loops - unnecessary. Those vendors must be getting nervous. " how so ??Arbie - Thursday, July 18, 2019 - link
Because, as I indicated, increasing the cooling on Ryzen 3000 CPUs does not appear to increase their boost clocks. I had certainly hoped otherwise. Beyond that, very few people will manually overclock Ryzen 3000 because that achieves nothing over PBO, except to waste power all the time.So why go to premium air? And why even consider water? Except on Intel, but any vendor dependent on sales of those chips ought to be very nervous - as I said. The niche markets involved are getting smaller (for air) and much smaller (for water).
