Noctua NH-U12S redux vs NH-U12S vs NH-U12A CPU Coolers Compared – Which One To Get?

Share this:

Noctua recently announced a new CPU cooler in addition to its redux line of products – the Noctua NH-U12S redux. This may be a little bit confusing due to the similarity of the product names. But the NH-U12S redux is based on the NH-U12S ( cooler reduced to its essential core. You can also say that it’s a budget-friendly version of its predecessor. In this article, let’s do a quick comparison between the NH-U12S redux vs NH-U12S and the popular NH-U12A CPU air cooler.

Noctua NH-U12S redux Is A Budget-Friendly CPU Air Cooler

The NH-U12S redux is the newest addition to Noctua’s NH-U12 series of CPU coolers. It’s a streamlined version with only the essentials are left, thus resulting in a more affordable price.

It uses the same heatsink layout as the other NH-U12 that guarantees compatibility with tall RAM modules and PCIe compatibility. The NH-U12S redux is paired by an NF-P12 redux-1700 PWM 120mm fan. Also, like the other Noctua CPU coolers, this one features SecuFirm2 mounting system; for easy installation. It doesn’t come with an extra thermal paste tube, but an NT-H1 thermal compound is pre-applied.

Looking at the table above, there are a few difference between the NH-U12S and the newer NH-U12S redux. But it has the same Noctua Standardized Performance Rating (NSPR) as the NH-U12S; despite having 1 less heatpipe and not a soldered interface. I haven’t tested this new CPU cooler yet, but I assume it will perform similarly with the NH-U12S. Perhaps, the NH-U12S ( might perform just a tad better.

However, do note that there are accessories that are missing on the redux variant. For example, the Low-Noice adapter is not included, and an extra NT-H1 thermal compound tube is not present as well. Also, the NF-F12 fan of the regular NH-U12S is 2.7dB(A) quieter than the NF-P12 redux-1700 PWM fan of the NH-U12S redux (22.4 vs. 25.1 dB(A)). You might want to consider the other if you want a silent operation.

Aesthetically speaking, only the NH-U12S features a black-coated heatsink. Luckily, the fan on the NH-U12S redux has a two-tone grey color theme. Perhaps, it’s more appealing compared to Noctua’s signature brown-colored fans. But if you want an all-black CPU cooler, the series would be your choice.

Noctua advises that for users who want the absolute best performance and noise efficiency, the NH-U12A is the obvious choice. We reviewed the NH-U12A CPU cooler and it’s a great performer. It is very silent and performs almost on par with a decent AIO liquid CPU cooler. The two NF-A12x25 PWM fans are state-of-the-art fans running at around 2.5dB2.7dB(A) more silent than the NH-U12s redux’s fan. Unfortunately, a black variant of this fan hasn’t been released yet.

Also, the NH-U12S redux CPU cooler doesn’t feature a soldered interface between the heatpipes and fins. Only the NH-U12A and NH-U12S have this feature. Finally, if you plan to do a push-pull configuration with the NH-U12S redux, you’ll need the optional NA-FK1 fan kit that is sold separately.

Where To Buy Noctua CPU Coolers
