Compare: NH-U14S vs Peerless Assassin 140

Design and Aesthetics:

NH-U14S

The Noctua NH-U14S sports a sleek and minimalist design, featuring a slim single-tower heatsink attached with Noctua's iconic brown and beige color scheme. A 140mm fan is attached, further enhancing its understated appearance.

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-U14S

The NH-U14S boasts a user-friendly mounting system that is compatible with a wide array of Intel and AMD sockets. Its straightforward installation process is facilitated by clear instructions and high-quality components.

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:

NH-U14S

With its six heat pipes and an extensive fin array, the NH-U14S delivers exceptional cooling performance. It is more than capable of handling high-end processors, maintaining optimal temperatures even under heavy workloads.

Peerless Assassin 140

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:

NH-U14S

Equipped with a 140mm NF-A15 PWM fan, the NH-U14S is designed for quiet operation. Striking a balance between cooling efficiency and noise, it is an ideal choice for users seeking a silent PC experience.

Peerless Assassin 140

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-U14S

The Noctua NH-U14S stands out as an excellent cooler, offering a simple yet attractive design, top-notch cooling performance, hassle-free installation, and impressively low noise levels. It is the perfect choice for those looking for a reliable and quiet cooling solution for their PC.

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.
