Compare: NH-U12S chromax.Black vs Peerless Assassin 140

Design and Aesthetics:

NH-U12S chromax.Black

The NH-U12S chromax.Black features a single-tower design with a slim aluminum heatsink and a single 120mm NF-F12 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 chromax.Black adopts a black color scheme, providing a sleek and modern appearance that complements various build themes.

Peerless Assassin 140

The Peerless Assassin 140 shares a similar design with other 140mm coolers from Thermalright, featuring two 140mm heatsinks paired with a 120mm fan at the front and a 140mm fan in the middle. The difference in fan sizes helps reduce RAM clearance issues, which are common with most 140mm air coolers. This model has a polished top and comes in an all-black design, though other color options may be available.

Install Notes:

NH-U12S chromax.Black

The NH-U12S 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 offers a relatively hassle-free installation process.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler features installation components similar to many mainstream Thermalright designs, making it relatively easy to install. However, it encounters a challenge when uninstalling, as it doesn't allow for sliding or twisting to break the thermal paste seal. This can be problematic if the thermal paste creates a strong bond between the cooler and the CPU.

Cooling Performance:

The performance of the NH-U12S is commendable due to its five 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, including high-end models with high TDPs. While it may not offer the same level of cooling performance as its bigger sibling, the NH-U12A, the NH-U12S still provides reliable cooling under various workloads and can handle moderate levels of overclocking under certain CPUs.

While the cooler offers similar peak performance to its competitors, its main advantage lies in its efficiency at lower RPMs, where it provides slightly better cooling. This translates to a noticeable edge in noise-to-performance ratio compared to smaller coolers, making it quieter under lower loads while still maintaining strong cooling capabilities.

Noise Performance:

One of the standout features of the NH-U12S is its quiet operation. The included 120mm NF-F12 PWM fan is designed for optimal airflow and low noise levels. Noctua fans are well-known for their excellent acoustic performance, and the NH-U12S is no exception. Users can expect quiet cooling even during normal computer use.

Due to its larger fans, this cooler becomes more audible at higher RPMs. However, because the fans move more air, lower RPMs are generally sufficient for cooling under most moderate CPU loads, allowing for quieter operation without sacrificing performance.

Summary:

NH-U12S chromax.Black

The Noctua NH-U12S is a reliable and efficient air cooler that offers excellent cooling capabilities and quiet operation. Its single-tower design and slim profile make it compatible with various system configurations, and its exceptional build quality ensures long-lasting performance. For users seeking a dependable cooling solution for their systems, the NH-U12S is a great choice.

Peerless Assassin 140

The Peerless Assassin 140 CPU cooler is easy to install, thanks to its design resembling other mainstream Thermalright models, but it presents a challenge during uninstallation as it doesn’t allow for sliding or twisting to break the thermal paste seal. It features two 140mm heatsinks, a 120mm fan at the front, and a 140mm fan in the middle, which helps reduce RAM clearance issues common with larger coolers. While its peak performance is on par with competitors, it excels at lower RPMs, offering better cooling and a superior noise-to-performance ratio compared to smaller coolers. Although more audible at higher RPMs due to its larger fans, the slower speeds still provide sufficient cooling for most moderate CPU loads, ensuring quieter operation without compromising performance.
