Compare: NH-U12S Redux vs NH-D15S

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-D15S

The NH-D15S features a dual-tower design with a large aluminum heatsink and one 140mm NF-A15 PWM fan. The asymmetrical layout of the cooler allows for improved clearance for RAM and PCIe slots, making it more versatile for different motherboard layouts. Aesthetically, the NH-D15S maintains Noctua's signature beige and brown color scheme, reflecting the brand's reputation for quality and performance.

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-D15S

The NH-D15S comes with Noctua's SecuFirm2 mounting system, which provides compatibility with a wide range of Intel and AMD sockets. The installation process is straightforward, thanks to the clear instructions and high-quality components provided. Noctua also includes a tube of their premium NT-H1 thermal compound to ensure optimal thermal transfer between the CPU and heatsink.

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-D15S

The performance of the NH-D15S is exceptional due to its six 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 CPUs to high-end models with high TDPs. The cooler can handle high levels of overclocking and provides reliable cooling under demanding situations, making it a popular choice among enthusiasts. However, given this cooler only uses a single fan, this version of the NH-D15 doesn't perform as well as the NH-D15.

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-D15S

One of the standout features of the NH-D15S is its quiet operation. The included 140mm NF-A15 PWM fan is designed for optimal airflow and low noise levels. Noctua fans are well-known for their excellent acoustic performance, and the NH-D15S is no exception. Users can expect quiet cooling even during intense workloads or gaming sessions.

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-D15S

The Noctua NH-D15S is a versatile, high-performance air cooler that offers excellent cooling capabilities and quiet operation. Its asymmetrical, dual-tower design makes it suitable for various system configurations, and its exceptional build quality ensures long-lasting performance. For users seeking a reliable and efficient cooling solution, the NH-D15S is a top choice.
