Brand Overview
Both the Thermalright Phantom Spirit 120 EVO and the Thermalright Assassin X 90 SE V2 are products from Thermalright, a reputable Taiwanese brand with over 20 years of experience in the CPU cooler market. This brand is well-regarded for its focus on research and development in computer accessories and cooling solutions.
While both coolers come from the same brand, the Phantom Spirit 120 EVO is priced at C$56.51, significantly higher than the Assassin X 90 SE V2, which is priced at just C$24.90. This price difference reflects the distinct features and performance levels each model offers.
Cooling Performance
In terms of cooling capability, the Thermalright Phantom Spirit 120 EVO is designed to provide superior heat dissipation with its 125mm x 135mm x 157mm dimensions and a high-speed fan capable of reaching 2150 RPM. This cooler features a larger surface area and advanced AGHP technology that enhances heat transfer efficiency.
On the other hand, the Assassin X 90 SE V2, measuring 94mm x 77mm x 118mm, employs a 4x6mm heatpipe layout and a PWM fan that operates at a maximum speed of 2200 RPM. While both coolers are designed to manage thermal output effectively, the Phantom Spirit 120 EVO’s larger size and higher RPM fan suggest that it may offer better cooling performance for high-demand applications.
Design and Build Quality
When examining the design and build quality, the Thermalright Phantom Spirit 120 EVO utilises an anodized black frosted top combined with a finely carved pure copper base. This combination not only enhances aesthetics but also contributes to its overall cooling efficiency. The cooler is constructed from durable PBT + PC materials, ensuring longevity.
Conversely, the Assassin X 90 SE V2 features an HDT direct touch process and a fully aluminium fin design, which also aids in maximising cooling efficiency. Its smaller stature makes it compatible with more compact chassis, appealing to users with limited space. While both coolers exhibit solid construction, the choice may come down to personal preference regarding size and aesthetic appeal.
Noise Levels
Noise levels are a crucial factor for many users when selecting a CPU cooler. The Phantom Spirit 120 EVO integrates a fan that balances high performance with aesthetics, but specific noise level metrics are not provided. However, its operational characteristics suggest that it may produce more noise due to its higher rotation speed.
In contrast, the Assassin X 90 SE V2 has a specified noise level of ≤23.85 dB(A), making it a quieter option for users who prioritise a silent operation. If low noise is a critical consideration, the Assassin X 90 SE V2 stands out as the better choice.
Compatibility
Compatibility is essential for ensuring that a CPU cooler can fit a variety of systems. The Phantom Spirit 120 EVO is designed to fit a wide range of setups, but specific CPU socket compatibility details are not mentioned.
The Assassin X 90 SE V2, however, explicitly lists compatibility with Intel sockets 1150, 1151, 1155, 1156, and 1200, along with AMD’s AM4 and AM5. This clear compatibility information makes the Assassin X 90 SE V2 a more straightforward choice for users concerned about fitting their cooler with existing CPU setups.
Fan Technology
Both coolers utilise advanced fan technologies to improve cooling efficiency. The Phantom Spirit 120 EVO features a fan that operates at a high rotation speed of 2150 RPM, promoting rapid heat dissipation. Its design includes ARGB lighting, adding a visual flair while performing cooling tasks.
In contrast, the Assassin X 90 SE V2’s fan operates at a slightly higher maximum speed of 2200 RPM, with an airflow rating of 32.77 CFM. This combination suggests that while both fans are effective, the Assassin X 90 SE V2 may have a slight edge in airflow performance, potentially translating to better cooling in certain scenarios.
Price Comparison
Price is a significant differentiator between these two coolers. The Thermalright Phantom Spirit 120 EVO is priced at C$56.51, reflecting its advanced features and larger size. In contrast, the Assassin X 90 SE V2 is much more budget-friendly at C$24.90.
For users looking for a cost-effective solution, the Assassin X 90 SE V2 offers excellent value without sacrificing performance. If a lower price point is essential for your build, the Assassin X 90 SE V2 could be the more appealing option.
Which should you buy?
Choosing between the Thermalright Phantom Spirit 120 EVO and the Thermalright Assassin X 90 SE V2 ultimately hinges on your specific needs and preferences. If you require superior cooling performance, a larger cooler, and are willing to invest more, the Phantom Spirit 120 EVO is the way to go.
However, if you are looking for a quieter operation, compact design, and a more budget-friendly option, the Assassin X 90 SE V2 is an excellent choice. Both coolers offer solid performance, but your decision should be guided by your system requirements and budget constraints.
