Dimension comparison
Brand Overview
Both the Thermalright Assassin X 120R SE Plus CPU Cooler and the Thermalright Phantom Spirit 120 CPU Cooler are products of the Taiwanese brand Thermalright, which has over 20 years of experience in the market. The brand has established a solid reputation for developing high-quality computer accessories, including CPU coolers. The Assassin X is priced at C$25.59, making it significantly more affordable than the Phantom Spirit, which retails for C$47.90. This price difference is noteworthy and may influence budget-conscious consumers.
Cooling Technology
The Thermalright Assassin X features four 6mm heat pipes that utilise the AGHP (Asymmetric Gravity Heat Pipe) technique, ensuring effective heat dissipation regardless of the cooler's orientation. In contrast, the Phantom Spirit boasts an upgraded AGHP technology with seven 6mm heat pipes, which may provide enhanced cooling efficiency. Both coolers are designed for a lifespan of up to 20,000 hours, which indicates a commitment to durability and long-term performance.
Fan Performance
When it comes to fan performance, the Assassin X employs double PWM fans with a maximum airflow of 66.17 CFM and operates at noise levels of up to 25.6 dB(A). This balance of airflow and noise level enhances the user experience, particularly for those who prioritise a quiet computing environment. The Phantom Spirit, while offering a slightly larger size and weight, does not explicitly detail its airflow or noise, making it challenging to compare performance metrics directly.
Design and Build Quality
The Thermalright Assassin X features a standard fan size of 120x120x25mm, which aligns with common case configurations, while the Phantom Spirit has dimensions of 125(L)x135(W)x157(H)mm. The design of the Phantom Spirit includes anodized black frosted top and finely carved pure copper base technology, potentially offering better aesthetics and thermal performance. The choice of materials in both coolers shows a commitment to quality, but the added aesthetic features of the Phantom Spirit may appeal to users who value both form and function.
Compatibility
Both coolers support a wide range of CPU socket types. The Assassin X is compatible with Intel sockets 1150 through 1700 and AMD sockets AM4 and AM5. Meanwhile, the Phantom Spirit also supports a similar range of Intel sockets (including LGA2011/2066) and AMD sockets, providing versatility for users upgrading or building systems. This broad compatibility ensures that both products can cater to a variety of setups, making them both viable options for different users.
Weight and Size
The Phantom Spirit weighs 0.945 kg, which is heavier than the Assassin X, though the exact weight of the latter is not specified. The larger dimensions of the Phantom Spirit may impact installation and compatibility with smaller cases. Users with compact builds may need to consider this factor when choosing between the two. However, the extra weight can also indicate a more robust cooling structure, which some users may prefer for enhanced thermal performance.
Price Comparison
Price is a significant differentiator between the two products. The Thermalright Assassin X is priced at C$25.59, making it a budget-friendly choice for users looking for effective cooling without breaking the bank. The Phantom Spirit, at C$47.90, positions itself as a premium product with potentially superior features and performance. The price difference of C$22.31 might be justified for users needing advanced cooling capabilities or those who prefer the design and build quality of the Phantom Spirit.
Which should you buy?
Choosing between the Thermalright Assassin X 120R SE Plus CPU Cooler and the Thermalright Phantom Spirit 120 CPU Cooler ultimately depends on your specific needs and budget. If you are looking for a more economical option that still delivers reliable cooling performance, the Assassin X at C$25.59 is an excellent choice. On the other hand, if you prefer advanced cooling technology, enhanced aesthetics, and are willing to invest more (C$47.90), the Phantom Spirit could be the better option for your build. Consider factors such as budget, case compatibility, and personal preferences in design when making your decision.
