Overview of Thermalright AXP90 X53 and Peerless Assassin 120 SE V2
The Thermalright AXP90 X53 is a low-profile cooler designed for small form factor builds, priced at C$45.99. In contrast, the Thermalright Peerless Assassin 120 SE V2 is a larger cooler aimed at delivering superior cooling performance, available for C$54.90. Both coolers are manufactured by Thermalright, a brand with over 20 years of experience in the cooling market.
The AXP90 X53 features a compact design with a height of only 53mm, making it ideal for ITX cases. On the other hand, the Peerless Assassin measures 155mm in height, which allows for a more robust cooling capability but may limit compatibility with smaller cases. Each cooler has its strengths tailored to different user needs and preferences.
Design and Build Quality
The design of the Thermalright AXP90 X53 is particularly suited for compact systems. It features a slim 92mm PWM fan and an overall height of just 53mm, making it compatible with many small motherboards. The AXP90 X53 utilises the AGHP technique, which effectively doubles the heat transfer efficiency through its innovative heat pipe design.
Conversely, the Peerless Assassin 120 SE V2 boasts a larger structure with dimensions of 125mm x 135mm x 155mm. This cooler employs six 6mm heat pipes and a dual fan setup, allowing for enhanced airflow and cooling performance. The build quality of both products is commendable, but the Peerless Assassin's larger dimensions provide it with a more substantial thermal management capability.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin 120 SE V2 clearly has the upper hand. With a thermal design power (TDP) rating of up to 265W, it is designed to handle high-performance CPUs. The dual fans can achieve a maximum airflow of 88.19 CFM, compared to the AXP90 X53’s single fan with a maximum speed of 2700 RPM, which is more suited for lower TDP CPUs.
The AXP90 X53 is effective for compact builds but is limited in its cooling capacity due to its smaller fan and dimensions. Users looking for extreme cooling capabilities for high-end processors will likely prefer the Peerless Assassin, which is engineered for demanding applications.
Compatibility
Compatibility is a significant factor when selecting a CPU cooler. The Thermalright AXP90 X53 supports a range of Intel and AMD sockets, including Intel LGA1700, 1150, 1151, 1155, 1156, 1200, and AMD’s AM4 and AM5. This broad compatibility makes it a versatile choice for many builds.
The Peerless Assassin also supports a wide variety of CPU sockets, including Intel LGA 1851, 1700, 1200, and 115X, alongside AMD AM4 and AM5. Both coolers come with the necessary mounting hardware, ensuring straightforward installation across various systems. Thus, while both products offer good compatibility, the choice may ultimately depend on the specific motherboard and CPU combination.
Noise Levels
Noise levels are crucial for many users, especially those who prefer quieter systems. The Thermalright AXP90 X53 operates with a fan designed to reduce vibration, contributing to a quieter performance. However, specific noise level metrics for this model are not provided.
In contrast, the Peerless Assassin 120 SE V2 has a maximum noise level of 29.5 dB(A), which is relatively quiet for a cooler of its size and performance capabilities. Users who favour a balance between performance and noise should consider how each cooler's specifications align with their personal preferences for acoustic output.
Installation Process
Both coolers offer relatively user-friendly installation processes, but there are some distinctions to note. The AXP90 X53 requires careful attention to the backplane installation, especially in cases with conflicting components. It includes long screws for attaching the backplane in a reversed position if needed.
The Peerless Assassin also provides a straightforward installation experience, with mounting plates and fasteners included for both Intel and AMD platforms. Given its larger size, users may find the installation of the Peerless Assassin slightly more challenging due to the cooler's dimensions, but it is still manageable for most users.
Price Comparison
Price plays a pivotal role in the decision-making process. The Thermalright AXP90 X53 is priced at C$45.99, making it an affordable option for budget-conscious builders, particularly those working on small form factor systems. In contrast, the Peerless Assassin 120 SE V2 is priced at C$54.90, reflecting its larger size and enhanced cooling capabilities.
While the price difference is only C$8.91, potential buyers should weigh the performance benefits of the Peerless Assassin against the lower-cost option of the AXP90 X53. Those who need superior cooling for high-performance tasks may find the additional investment worthwhile.
Which should you buy?
Ultimately, the choice between the Thermalright AXP90 X53 and the Peerless Assassin 120 SE V2 depends on your specific needs and build requirements. If you are working with a compact system and need a budget-friendly cooler, the AXP90 X53 is an excellent option. However, if you require superior cooling for high-performance CPUs and do not mind the larger size or slightly higher price, the Peerless Assassin 120 SE V2 is the better choice. Each cooler has its strengths, making them suitable for different types of users and applications.
