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.


The AK400 is a sleek and stylish air cooler that features a clean black top, complemented by a single 120mm black fan, designed for users who appreciate a minimalist aesthetic. The it's single-tower aluminum radiator efficiently dissipates heat, ensuring effective cooling for your CPU. This compact and unassuming cooler not only delivers efficient performance but also seamlessly integrates into a variety of PC builds, making it an ideal choice for those who value both form and function.

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.


This cooler is moderately difficult to install and is more difficult than other DeepCool cooler installations. For AMD CPU's, the mounting setup can be difficult to place due to the mounting bracket doesn't secure through holes, but rather through notches for the AMD setups (This isn't a problem for Intel setups). For this reason, keeping the backplate flush against the motherboard while also keeping the install components in line may prove to be difficult and may require a second pair of hands. This also has a very similar installation to the AG400.

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.


The AK400 delivers impressive cooling performance for its size, attributed to its four heat pipes that effectively transfer heat from the CPU to the extensive fin array on the heatsink. It is well-suited for up to moderate-level processors; however, it might not be the best choice for high TDP CPUs or those looking to overclock their systems.

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.


This CPU cooler offers average cooling performance and operates at a moderate noise level. While it may not be the quietest option on the market, it maintains a comfortable balance between cooling efficiency and acoustic performance. This cooler is suitable for users who are not particularly sensitive to noise and are seeking a cost-effective solution for maintaining stable temperatures in their systems without demanding top-tier cooling or silent operation.


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.


This cooler has a moderately difficult installation, especially for AMD CPUs, due to its unique mounting setup. The installation process is similar to the AG400. The AK400 has a compact design, moderate cooling performance, and above-average noise levels. With a sleek, minimalist aesthetic, the cooler is suitable for various PC builds, offering a balance between cooling efficiency and acoustic performance for users seeking cost-effective solutions without top-tier cooling or silent operation.
