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.

Average Thermal Resistance

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.

    I was on board until the price. I paid £60 for my NH-D14 and expected a price bump considering it's now 8 years old, but nearly double the price is a bit too far.

    The pound isn't worth what it used to be eight years ago, either:

    Noctua isn’t an American company

    nor the pound an American currency

    Nice to see a new cooler review. Hopefully more can come down the pipeline and get rid of the old coolers on here that you can't even buy.

    Thanks for the review. Two questions/comments:
    1. You mentioned the Evo212 in some paragraphs and a graph. I also believe that this is a good comparison cooler, as it also addresses price/performance. And, while the Noctua is a bit of a niche product, I would have like to see how it did compared to the higher priced "extra quiet" heatsinks shown. If you have the data, could you share them?
    2. I know that many people who are looking for that kind of cooler wouldn't care for whatever setup came with their CPU. However, those have the best price - free (with the CPU). It would be nice to know just how much extra thermal performance one gets by replacing the coolers that come with the CPU. May suggestion is to show the performance of the respective boxed Intel and AMD cooler alongside. With AMD making noise about their Wraith Spire cooler's performance (included with most of their desktop CPUs), I would really like to know just how much better these aftermarket ones are. Thanks!

    For question 1. "It refers to the 212 cooler, the Noctua is obviously already shown.

    I second the suggestion for comparing it to the wraith (spire), esp with Ryzen's PBO.

    I always liked the NH-U14S there going for low 60$ (about same as NH-U12S). You do need a case to support the height.

    I'd absolutely love to find out how the newest Noctuas (UH12A, NH-U14S NH-D15, NH-D15S) compare to the older NH-D14, NU-U12S, and the Thermalright TRUE 120.

    The results on Noctua's new gear is amazing, but I contacted Thermalright to ask about heat dissipation for my TRUE Black 120 from 2008, and found it's rated for a stunning 240 watts. I have two Noctua Redux 120mm 1300rpm fans on it and it's keeping a Core i9-9900K (running all eight cores at max turbo 4.8GHz at 100% usage in Folding@Home) stable , a bit over 80C at 160+ watts load under constant use. An eleven year old (admittedly heavy nickel-plate copper with six heat pipes) cooler. I'm still impressed.

    I'd love to know how far we've really come since the D14 and TRUE120 just to see if there's a significant difference.
