Dimension comparison
Brand Overview
Both the Thermalright Phantom Spirit 120 EVO and the Thermalright Assassin X 120 SE ARGB are products from the well-established Taiwanese brand Thermalright, which has over 20 years of experience in the computer cooling market. The Phantom Spirit 120 EVO is priced at C$56.51, while the Assassin X 120 SE ARGB is considerably more affordable at C$24.29. This price difference reflects their respective market positioning and features, indicating that while both are reliable choices, they cater to different consumer needs and budgets.
Design and Dimensions
The Thermalright Phantom Spirit 120 EVO features dimensions of 125mm x 135mm x 157mm, making it a robust option for cooling performance. In contrast, the Thermalright Assassin X 120 SE ARGB has a more compact design with dimensions of 125mm x 71mm x 148mm. This difference in design can influence the choice between the two; users with limited space in their cases may prefer the slimmer profile of the Assassin X, while those looking for enhanced cooling capability may lean towards the larger Phantom Spirit.
Cooling Performance
Cooling performance is a vital aspect when choosing a CPU cooler. The Phantom Spirit 120 EVO boasts a high fan rotation speed of 2150 RPM, designed to efficiently dissipate heat. On the other hand, the Assassin X 120 SE ARGB operates at a slightly lower RPM of 1550, which could mean less aggressive cooling but also potentially quieter operation. The Phantom Spirit’s emphasis on higher RPM suggests it might be better suited for users who push their CPUs to the limit, while the Assassin X may appeal to those prioritising quieter performance.
Fan Technology
Both CPU coolers utilise advanced fan technology, but with different specifications that may appeal to varying preferences. The Phantom Spirit 120 EVO incorporates a fan equipped with four rounded ARGB lines, providing aesthetic appeal alongside functionality. It operates at a high rotation speed of 2150 RPM, ensuring effective heat management. In contrast, the Assassin X 120 SE ARGB features a PWM fan that balances efficiency and noise, with a maximum airflow of 66.17 CFM and a noise level capped at 25.6 dB(A). This makes the Assassin X a compelling option for users looking for a quieter experience without sacrificing cooling performance.
Build Quality and Materials
When it comes to build quality, both coolers are constructed from high-grade materials designed for durability. The Phantom Spirit 120 EVO uses industrial strength PBT + PC material and features a finely carved pure copper base, while the Assassin X 120 SE ARGB also utilises aluminum for its heat sink and includes metal fasteners for better installation. Both coolers promise a long service life of up to 20,000 hours, but the choice of materials may lead users to prefer the more premium feel of the Phantom Spirit.
Compatibility
Compatibility is crucial for ensuring a seamless installation. The Assassin X 120 SE ARGB supports a variety of CPU sockets, including Intel’s 115X/1200/1700 and AMD’s AM4, with corresponding mounting plates provided for ease of setup. The Phantom Spirit 120 EVO does not explicitly mention socket compatibility in the provided data, which could be a concern for potential buyers looking for assurance that the cooler will fit their system. Users should confirm compatibility with their specific setup to avoid any installation issues.
Price Comparison
Price plays a significant role in the decision-making process for consumers. The Phantom Spirit 120 EVO is positioned at C$56.51, whereas the Assassin X 120 SE ARGB is priced at a more budget-friendly C$24.29. This substantial price difference of C$32.22 may lead buyers to consider what features they value most. If aesthetics, a higher RPM, and potentially better cooling performance are priorities, the Phantom Spirit may justify its higher cost. Conversely, the Assassin X offers excellent value for users looking for effective cooling on a budget.
Which should you buy?
Ultimately, the decision between the Thermalright Phantom Spirit 120 EVO and the Thermalright Assassin X 120 SE ARGB comes down to individual needs and preferences. The Phantom Spirit is ideal for users seeking maximum cooling performance and premium features, while the Assassin X is an excellent choice for those prioritising quiet operation and affordability. If budget constraints are a primary concern, the Assassin X is the clear winner. However, for those willing to invest more for enhanced cooling and aesthetics, the Phantom Spirit stands out as a superior option.
