Thermalright AXP90 X47 Full Low Profile CPU Cooler vs Thermalright Assassin Spirit 120 EVO Dark CPU Cooler Air with 4×6mm HeatPipes

Brand Overview

Both the Thermalright AXP90 X47 Full Low Profile CPU Cooler and the Thermalright Assassin Spirit 120 EVO Dark CPU Cooler are products of Thermalright, a Taiwanese brand with over 20 years of experience in the cooling market. The AXP90 X47 is priced at C$43.39, while the Assassin Spirit 120 EVO Dark comes in significantly lower at C$24.90. This price difference indicates a potential variance in features and performance, which is typical for products targeting different segments of the market.

The AXP90 X47 is designed with a focus on compactness, making it suitable for small form factor builds, such as HTPCs and ITX systems. On the other hand, the Assassin Spirit 120 EVO Dark offers a broader cooling solution with a larger footprint and potentially more robust cooling capabilities, appealing to users who may require more cooling power.

Cooling Performance

The Thermalright AXP90 X47 features AGHP technology with four 6mm heat pipes, designed to enhance cooling efficiency by addressing the inverse gravity effect. This cooler can achieve an impressive maximum air volume of 42.58 CFM and operates at a maximum speed of 2700 RPM, producing a noise level of 22.4 dB(A).

In contrast, the Assassin Spirit 120 EVO Dark utilises a 4×6mm heat pipe setup and an aluminium construction that optimally increases the heat dissipation area. While it has a lower maximum fan speed of 1850 RPM, the high-speed PWM fan aims to improve cooling efficiency dynamically. The AXP90 X47 may have a slight edge in terms of air volume, but the overall efficacy could depend on the specific use case and case airflow.

Design and Build Quality

The AXP90 X47 stands out with its low-profile design, measuring just 47mm in height. This compact form factor is ideal for installations where space is at a premium, eliminating concerns about memory clearance. The cooler is constructed from pure copper, which not only enhances heat conductivity but also increases oxidation resistance.

Conversely, the Assassin Spirit 120 EVO Dark showcases a more traditional tower design, measuring 120mm in length and 156mm in height. Its all-aluminium fins and unique anodised black brushed top cover provide a stylish appearance while improving cooling efficiency. Both coolers exhibit quality craftsmanship, but their designs cater to different user needs—compact vs. expansive.

Compatibility

The Thermalright AXP90 X47 supports a wide range of CPU sockets, including Intel's LGA1700, 1150, 1151, 1155, 1156, and 1200, as well as AMD's AM4 and AM5. This broad compatibility makes it versatile for various builds without needing additional mounting hardware.

On the other hand, the Assassin Spirit 120 EVO Dark also offers extensive compatibility with Intel's LGA1150, 1151, 1155, 1156, 1200, and 1700 sockets, along with AMD's AM4 and AM5. Both products ensure that users can find a suitable installation method for their systems, but the AXP90 X47 might be more appealing for those with space-constrained builds.

Noise Levels

When it comes to noise levels, the AXP90 X47 operates at a maximum of 22.4 dB(A), making it a quiet option for users who prioritise a low-noise environment. The PWM fan is designed for automatic temperature control, ensuring that it runs only as fast as necessary.

In comparison, the Assassin Spirit 120 EVO Dark does not specify its noise levels but features a PWM temperature control function that adjusts the fan speed based on the CPU's thermal demands. While the AXP90 X47's noise level is clearly defined, the lack of a specified noise figure for the Assassin Spirit leaves some uncertainty about its performance in terms of acoustics.

Price Point

The AXP90 X47 is priced at C$43.39, reflecting its advanced technology and compact design, making it suitable for users who need efficient cooling in tight spaces. In contrast, the Assassin Spirit 120 EVO Dark is priced at C$24.90, making it a more budget-friendly option that still delivers solid performance.

This substantial price difference of C$18.49 could influence purchasing decisions, especially for budget-conscious consumers who still want reliable cooling without compromising too much on performance.

User Experience

Users of the Thermalright AXP90 X47 often appreciate its straightforward installation process due to its broad compatibility and accompanying installation video. The cooler’s low profile is also a significant advantage for those building compact PCs.

Meanwhile, the Assassin Spirit 120 EVO Dark is noted for its excellent price-to-performance ratio. Users enjoy the ease of installation with the included mounting plates and fasteners, highlighting its user-friendly nature. However, those who require higher performance cooling might find it slightly lacking compared to more premium models.

Which should you buy?

Choosing between the Thermalright AXP90 X47 and the Assassin Spirit 120 EVO Dark ultimately depends on your specific needs and preferences. If you require a compact solution for a small form factor build and are willing to invest a bit more for advanced cooling technology, the AXP90 X47 at C$43.39 is an excellent choice. Its low profile and effective cooling capabilities make it ideal for HTPCs and ITX systems.

Conversely, if you are looking for an economical option that still provides good performance and broader compatibility, the Assassin Spirit 120 EVO Dark at C$24.90 offers great value. It is suitable for standard builds where space is less of a concern. In summary, both coolers deliver quality performance, but your choice should reflect your system requirements and budget considerations.
