Thermalright Peerless Assassin 140 Black CPU Cooler vs Thermalright Assassin X 90 SE V2 CPU Cooler

Pricing Comparison

The Thermalright Peerless Assassin 140 Black CPU Cooler is priced at C$54.90, while the Thermalright Assassin X 90 SE V2 CPU Cooler is significantly more affordable at C$24.90. This price difference of C$30 indicates that the Peerless Assassin 140 Black is positioned as a premium option, likely reflecting its advanced cooling capabilities and larger size. The Assassin X 90 SE V2, on the other hand, offers a budget-friendly solution for users looking for essential cooling performance without breaking the bank.

Cooling Performance

When it comes to cooling performance, the Thermalright Peerless Assassin 140 Black stands out with its dual fans and a maximum airflow of 66.17 CFM, compared to the Assassin X 90 SE V2's maximum airflow of 32.77 CFM. The Peerless model features a twin-tower design equipped with six pure copper heat pipes, enhancing heat dissipation efficiency. In contrast, the Assassin X 90 SE V2 utilises a single 92mm fan that operates at a higher RPM of 2200, but with considerably less airflow. This suggests that while the Assassin X 90 SE V2 is effective for basic cooling needs, the Peerless Assassin 140 Black is better suited for high-performance CPUs or overclocking scenarios.

Size and Compatibility

The Thermalright Peerless Assassin 140 Black measures 140mm x 157mm x 158mm, making it a larger cooler that fits well in medium to large cases. Its height of 158mm allows compatibility with high-profile memory and graphics cards. Conversely, the Thermalright Assassin X 90 SE V2 has a more compact size of 94mm x 77mm x 118mm, making it a better choice for smaller chassis. Both coolers support a variety of CPU sockets, including Intel 1150 through 1700 and AMD AM4/AM5, ensuring broad compatibility across different systems.

Build Quality and Design

The build quality of the Thermalright Peerless Assassin 140 Black is enhanced by its dual-tower design and all-aluminium fins, aimed at maximizing the cooling surface area. The use of pure copper heat pipes further boosts its heat dissipation capabilities. In contrast, the Thermalright Assassin X 90 SE V2 incorporates a direct touch technology and is made from aluminum with S-FDB bearings, which contribute to its durability and performance. While both models boast quality materials, the Peerless Assassin 140 Black's design leans towards more advanced cooling technology, making it suitable for demanding applications.

Noise Levels

The Thermalright Peerless Assassin 140 Black operates at a noise level of 25.6 dB(A), making it a relatively quiet option for users who are sensitive to sound. The Assassin X 90 SE V2, with its maximum noise level of 23.85 dB(A), is slightly quieter but operates at lower airflow. While both coolers are designed to minimize noise, the difference in noise levels is marginal and may not be a significant deciding factor for most users.

Fan Technology

Fan technology differs significantly between the two models. The Peerless Assassin 140 Black features dual PWM fans that can adjust their speed for efficient cooling, while the Assassin X 90 SE V2 uses a single PWM fan that provides a higher RPM but lower airflow. The dual-fan setup in the Peerless model allows for more effective heat dissipation, especially under heavy loads. This aspect makes the Peerless Assassin 140 Black a better choice for users looking for sustained performance during intense gaming or heavy multitasking.

Brand Reputation

Both coolers come from Thermalright, a brand with over 20 years of experience in the cooling market. Known for their innovative designs and reliable performance, Thermalright has established a strong reputation among PC enthusiasts. The Peerless Assassin 140 Black is viewed as a premium product within the brand’s lineup, while the Assassin X 90 SE V2 serves as a more budget-friendly option that still carries the quality associated with Thermalright products.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 140 Black and the Assassin X 90 SE V2 ultimately depends on your specific needs and budget. If you require superior cooling performance for high-end CPUs and are willing to invest more, the Peerless Assassin 140 Black, with its advanced dual-tower design and higher airflow, is the better option at C$54.90. However, if you are looking for a more compact cooler that is easy on the wallet and adequate for standard usage, the Assassin X 90 SE V2 at C$24.90 provides excellent value for money.
