Dimension comparison
Overview of Thermalright Phantom Spirit 120 and Assassin X 90 SE V2
When comparing the Thermalright Phantom Spirit 120 and the Assassin X 90 SE V2, the most notable difference is their price and size. The Phantom Spirit 120 is priced at C$47.90, while the Assassin X 90 SE V2 is significantly cheaper at C$24.90. This price disparity suggests that each cooler targets different segments of the market. The Phantom Spirit 120 is designed for users looking for higher performance and larger cooling capabilities, while the Assassin X 90 SE V2 appeals to budget-conscious consumers needing efficient cooling without breaking the bank.
Dimensions and Compatibility
The Thermalright Phantom Spirit 120 boasts dimensions of 125mm x 135mm x 157mm, making it a larger option compared to the Assassin X 90 SE V2, which measures 94mm x 77mm x 118mm. The height of the Phantom Spirit 120 allows it to fit into a wide range of chassis, thanks to its 157mm height. In contrast, the Assassin X 90 SE V2, at 118mm tall, is also compatible with various chassis but is better suited for smaller builds. Both coolers support a range of CPU sockets across Intel and AMD platforms, ensuring versatility in installation.
Cooling Technology
The Phantom Spirit 120 employs an advanced AGHP technique with 7x6mm heat pipes designed for optimal heat dissipation, while the Assassin X 90 SE V2 uses a 4x6mm configuration. The larger heat pipes in the Phantom Spirit 120 suggest it may have a superior cooling capacity, especially under heavy loads. Both coolers promise up to 20,000 hours of service life due to S-FDB bearings, but the Phantom Spirit's design is aimed at maximizing the cooling surface area, which could translate to better performance in demanding scenarios.
Fan Performance
The Phantom Spirit 120 features a fan configuration designed for low noise and effective cooling, although specific RPM and airflow values aren't provided in the data. The Assassin X 90 SE V2, however, includes a PWM fan that operates at a maximum speed of 2200 RPM and achieves an airflow of 32.77 CFM while maintaining a noise level of ≤23.85 dB(A). This performance indicates that while the Phantom Spirit 120 may provide enhanced cooling, the Assassin X 90 SE V2 could offer a quieter operation, making it suitable for users prioritizing low noise levels.
Material Quality and Build
Both products are made from high-quality materials. The Phantom Spirit 120 features an anodized black frosted top, finely carved pure copper base technology, and aluminum fins to enhance heat dissipation. The Assassin X 90 SE V2 also utilises aluminum for its heat sink and incorporates a direct touch technology for efficient thermal transfer. While the materials are comparable, the Phantom Spirit 120's more extensive use of copper suggests it may provide better thermal conductivity, which is critical for high-performance cooling.
Use Cases
The Thermalright Phantom Spirit 120 is better suited for users who engage in overclocking or run high-performance setups that demand exceptional cooling. Its larger size and advanced cooling technology cater to enthusiasts seeking maximum performance. Conversely, the Assassin X 90 SE V2 is ideal for budget-minded users or those with smaller cases who still require reliable cooling for standard operations. It is a solid choice for everyday computing tasks and light gaming without the need for extreme cooling solutions.
Price Comparison
The price difference is a significant factor in this comparison. The Phantom Spirit 120 retails for C$47.90, while the Assassin X 90 SE V2 is priced at C$24.90. This nearly 50% price difference can influence purchasing decisions, especially for those on a budget or those building a cost-effective system. While the Phantom Spirit 120 may justify its higher price through enhanced cooling capabilities, the Assassin X 90 SE V2 provides excellent value for users who do not require top-tier cooling performance.
Which should you buy?
Choosing between the Thermalright Phantom Spirit 120 and the Assassin X 90 SE V2 ultimately comes down to your specific needs and budget. If you require superior cooling performance for high-end tasks, the Phantom Spirit 120 is the better option, offering advanced technology and larger dimensions for effective heat dissipation. However, if you are on a budget or need a cooler for a compact build, the Assassin X 90 SE V2 stands out as an economical choice without compromising essential cooling capabilities.
