Compare: Mugen 5 Rev. C vs Peerless Assassin 140

Design and Aesthetics:

Mugen 5 Rev. C

The Mugen 5 Rev. C features a single-tower design with a large aluminum heatsink and a single 120mm Kaze Flex fan. This design ensures efficient heat dissipation while allowing compatibility with different system configurations, including those with tall RAM modules. Aesthetically, the Mugen 5 Rev. C has a sleek and modern appearance with a silver and black color scheme 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:

Mugen 5 Rev. C

The Scythe Mugen 5 Rev. C comes with a mounting system that offers compatibility with a wide variety of Intel and AMD sockets. The installation process is relatively straightforward, thanks to the detailed instructions and high-quality components provided. This cooler employs a similar method to the Noctua installation, but with a slight alteration in the male and female connectors on the cooler's mounting system. This modification allows for easy installation and removal of the cooler. However, to ensure optimal cooling performance, it's essential to carefully follow the instructions and achieve proper mounting.

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:

Mugen 5 Rev. C

The performance of the Mugen 5 Rev. C 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, including some high-end models with high TDPs. The cooler can handle moderate levels of overclocking on mid-level CPUs and provides reliable cooling under demanding situations, making it a popular choice among PC enthusiasts.

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:

Mugen 5 Rev. C

One of the standout features of the Mugen 5 Rev. C is its quiet operation. The included 120mm Kaze Flex fan is designed for optimal airflow and low noise levels. Scythe fans are known for their excellent acoustic performance, and the Mugen 5 Rev. C upholds this reputation. Users can expect quiet cooling even during moderate workloads or gaming sessions.

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:

Mugen 5 Rev. C

The Mugen 5 Rev. C is a high-performance air cooler that offers excellent cooling capabilities and quiet operation. Its single-tower design and sleek aesthetics make it an attractive option for users seeking a reliable and efficient cooling solution for their PC systems.

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.
