Design and Aesthetics:


NH-U12S Redux

The NH-U12S redux features a single-tower design with a slim aluminum heatsink and a single 120mm NF-P12 redux-1700 PWM fan. This design ensures efficient heat dissipation while maintaining compatibility with various system configurations, including those with tall RAM modules. Aesthetically, the NH-U12S redux adopts a more neutral gray color scheme, providing a sleek and modern appearance that complements various build themes.

NH-D15 G2

This cooler is quite large and showcases Noctua's signature design, appealing to diehard PC builders who don't want to compromise on cooling performance. The NH-D15 G2 closely resembles the previous generation, with a few updates. This version features eight heat pipes and offset depths on the two heatsinks


Install Notes:


NH-U12S Redux

The NH-U12S Redux features Noctua's SecuFirm2 mounting system, ensuring compatibility with a wide range of Intel and AMD sockets and offering a straightforward installation process, typical of Noctua coolers. Clear instructions, high-quality components, and a tube of their premium NT-H1 thermal compound make it an easy and user-friendly experience, even for beginners. The cooler uses the original AMD backplate for AMD installations. However, one downside is that the cooler may stick to your CPU, and due to the screw setup, you can't slide the cooler off the CPU like with some other brands. Overall, the NH-U12S Redux offers a relatively hassle-free installation process.

NH-D15 G2

The NH-D15 G2 retains the same installation design as its predecessor, with the addition of a new bracket that allows for offset mounting on AM5 CPUs. The installation process is straightforward, guided by clear instructions that adhere to industry standards for top-tier coolers. However, the cooler's large size may pose challenges when maneuvering it within the case.




Cooling Performance:


NH-U12S Redux

The performance of the NH-U12S redux is solid, thanks to its four heat pipes that efficiently transfer heat away from the CPU and into the large fin array of the heatsink. It is suitable for a wide range of processors, from mainstream to some high-end models. While it may not offer the same level of cooling performance as the original NH-U12S, the NH-U12S redux still provides reliable cooling under various workloads and can handle moderate levels of overclocking.

NH-D15 G2

The Noctua's NH-D15 G2 cooler is hard to beat in terms of cooling performance, even outperforming AIOs from various other brands—a result expected given its larger size. However, when compared to the previous generation, its performance is on par, offering little improvement.


Noise Performance:


NH-U12S Redux

The NH-U12S redux maintains Noctua's commitment to quiet operation. The included 120mm NF-P12 redux-1700 PWM fan is designed for optimal airflow and low noise levels. Noctua fans are known for their excellent acoustic performance, and the NH-U12S redux upholds this reputation. Users can expect quiet cooling even during normal computer use.

NH-D15 G2

Compared to the average cooler, the Noctua NH-D15 G2 is louder than most on the market. However, when performance is evaluated on a noise-normalized basis, this cooler is tough to beat, offering excellent cooling for a given noise level. This means you can keep your cooler quiet when needed, while still having the headroom to increase the speed for enhanced cooling performance.


Summary:


NH-U12S Redux

The Noctua NH-U12S redux is an affordable and efficient air cooler that offers good cooling capabilities and quiet operation. Its single-tower design and slim profile make it compatible with various system configurations, while its more neutral color scheme adds a modern touch. For users seeking a cost-effective cooling solution without compromising on quality, the NH-U12S redux is an excellent choice.

NH-D15 G2

The Noctua NH-D15 G2 retains the familiar installation design of its predecessor, with the addition of a new bracket for offset mounting on AM5 CPUs. While its large size may make installation a bit challenging, the process is straightforward, with clear instructions that meet industry standards. The cooler's substantial size is matched by its performance, offering exceptional cooling that even surpasses many AIOs from other brands. Although its performance is on par with the previous generation, the NH-D15 G2 still delivers excellent cooling, particularly when considering noise levels. Despite being louder than the average cooler, it excels in noise-normalized performance, allowing users to maintain quiet operation while having the flexibility to ramp up speed for maximum cooling when needed.
