Dimension comparison
Pricing Comparison
The Thermalright Phantom Spirit 120 SE Black CPU Air Cooler is priced at C$46.71, making it a more budget-friendly option compared to the Thermalright Peerless Assassin 120, which retails for C$51.39. This C$4.68 difference may seem minor but can be significant for users looking to maximise their value while building or upgrading their systems. Both coolers are designed to deliver efficient cooling performance, but the lower price point of the Phantom Spirit makes it an attractive choice for cost-conscious consumers.
Cooling Performance
In terms of cooling performance, the Phantom Spirit boasts enhanced features with its blackened nano coating and fully electroplated heat pipes. This design aims to increase the effective heat dissipation area, which is crucial for maintaining optimal CPU temperatures. On the other hand, the Peerless Assassin has a documented effective heat dissipation area of 9600 cm², which may provide superior cooling capabilities due to its double tower configuration and six heat pipes. The Peerless Assassin supports a TDP of 245W, indicating it is built to handle higher thermal loads, making it potentially more suitable for high-performance systems.
Design and Build Quality
The Phantom Spirit features a height of 154 mm, which ensures compatibility with a variety of chassis without interfering with memory modules or other components. Its construction includes anodized black frosted top pieces and finely carved pure copper base technology, aimed at maximising heat dissipation. In contrast, the Peerless Assassin, with a height of 157 mm, employs a white nanoscale spray for its twin towers, adding a unique aesthetic appeal. Both products are made from high-quality materials, but the choice between a sleek black or a vibrant white design may cater to different user preferences.
Fan Technology
The Phantom Spirit is equipped with S-FDB bearings that contribute to its longevity and reliable performance, promising an impressive operational lifespan of up to 20,000 hours. Meanwhile, the Peerless Assassin features two PWM fans with a maximum airflow of 66.17 CFM and a noise level of 25.6 dB(A), allowing for a quieter operation while maintaining effective cooling. The ability to control RGB lighting effects on the Peerless Assassin adds an extra layer of appeal for users who value aesthetics in their builds, whereas the Phantom Spirit focuses more on functional design.
Compatibility
Both coolers offer broad compatibility with various CPU sockets. The Phantom Spirit supports Intel sockets LGA1851, 1700, 1150, 1151, 1155, 1156, and 1200, as well as AMD sockets AM4 and AM5. Similarly, the Peerless Assassin is compatible with Intel sockets 1150, 1151, 1155, 1156, 1200, 1700, 17XX, 2066, and 2011, along with AMD AM4 and AM5. The inclusion of corresponding mounting plates and fasteners with both products ensures that installation is straightforward, but the Peerless Assassin's versatility with more Intel socket options may appeal to users with specific build requirements.
Installation Process
When it comes to installation, both coolers provide ample support with their respective mounting systems. The Phantom Spirit's instructions and mounting plates are designed to facilitate a hassle-free setup, while the Peerless Assassin includes metal fasteners for better installation stability. The Phantom Spirit's design avoids interference with memory chips, making it easier to install in tight spaces. The offset asymmetric layout of the Peerless Assassin allows for unrestricted installation around the first graphics card slot, which may be a significant advantage for users with limited space.
User Experience and Noise Levels
User experience can greatly affect the overall satisfaction with a cooling product. The Phantom Spirit is designed for quiet operation, thanks to its durable S-FDB bearings, which help in reducing noise levels during operation. On the other hand, while the Peerless Assassin operates at a slightly higher noise level of 25.6 dB(A), it compensates with superior cooling performance and the allure of RGB lighting. Users who prioritise low noise levels may lean towards the Phantom Spirit, while those who appreciate enhanced aesthetics and cooling capacity might prefer the Peerless Assassin.
Which should you buy?
In conclusion, the choice between the Thermalright Phantom Spirit 120 SE Black CPU Air Cooler and the Thermalright Peerless Assassin 120 CPU Air Cooler ultimately depends on your specific needs and preferences. If you are looking for a more affordable option with quiet operation and solid performance, the Phantom Spirit is an excellent choice at C$46.71. However, if you are willing to spend a bit more for superior cooling performance, aesthetic appeal with RGB lighting, and broader compatibility with Intel sockets, the Peerless Assassin at C$51.39 may be the better investment. Both coolers are well-engineered products that cater to different user demands, ensuring that either choice will enhance your CPU cooling experience.
