Compare: Fuma 2 Rev. B vs Peerless Assassin 140

Design and Aesthetics:

Fuma 2 Rev. B

The Scythe Fuma 2 Rev. B features a dual-tower design with two slim aluminum heatsinks and a pair of 120mm Kaze Flex fans. This design ensures efficient heat dissipation and allows for compatibility with various system configurations, including those with tall RAM modules. Aesthetically, the Fuma 2 Rev. B has a sleek, modern appearance with a black and gray color scheme that complements a variety of 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:

Fuma 2 Rev. B

The Scythe Fuma 2 Rev. B 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:

Fuma 2 Rev. B

The performance of the Scythe Fuma 2 Rev. B is exceptional due to its six heat pipes that efficiently transfer heat away from the CPU and into the large fin arrays of the heatsinks. It is suitable for a wide range of processors, including moderate to low level TDPs. The cooler may not be suitable for high levels of overclocking but it is a popular choice among enthusiasts for mainstream CPUs.

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:

Fuma 2 Rev. B

One of the key attributes of the Scythe Fuma 2 Rev. B is its moderate noise output. The dual 120mm Kaze Flex fans are engineered for maximum airflow and moderate noise levels. Users can anticipate quiet cooling under most workloads.

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:

Fuma 2 Rev. B

The Scythe Fuma 2 Rev. B is a high-caliber air cooler that offers exceptional cooling performance and quiet operation. Its dual-tower design and modern aesthetics make it an appealing choice for users in search of a dependable and efficient cooling solution for high-performance computing 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.
