Overview of the Thermalright Phantom Spirit 120 EVO CPU Cooler
On the other hand, the Thermalright Phantom Spirit 120 EVO CPU Cooler comes at a higher price of $46.90, representing about 136% more than the Assassin King. This cooler features seven heat pipes and dual PWM fans that can reach speeds of 2150 RPM, offering superior cooling performance. Its dimensions are larger at 125(L)x135(W)x157(H)mm, which may require more space in your case. The Phantom Spirit's design includes a precision micro-engraved copper base and a frosted finish, enhancing both performance and aesthetics. The noise level peaks at 27 dB(A), slightly higher than the Assassin King, but still within a reasonable range for a high-performance cooler.
Cooling Performance Comparison
When it comes to cooling performance, the Thermalright Phantom Spirit 120 EVO stands out with its dual fan setup and higher RPM capability, providing an air flow of 69 CFM compared to the Assassin King's 66.17 CFM. This translates to potentially better thermal management under load, which is crucial for high-performance CPUs. The additional heat pipe in the Phantom Spirit further enhances its heat dissipation efficiency, making it a better choice for overclockers or those who run demanding applications. Conversely, the Assassin King, while less powerful, still offers solid cooling performance for budget builds or less demanding setups.
Noise Levels and Fan Efficiency
In terms of noise levels, the Thermalright Assassin King is quieter, operating at a maximum of 25.6 dB(A) compared to the Phantom Spirit's 27 dB(A). For users sensitive to noise, this could be a deciding factor. The Assassin King's fan operates at a slightly lower RPM, which contributes to its quieter performance. However, the Phantom Spirit's dual fans, while marginally louder, provide better cooling efficiency, making them ideal for gaming or intensive tasks where performance outweighs the need for silence. Both fans utilize PWM technology, allowing for dynamic speed adjustments based on temperature, which helps maintain a balance between cooling and noise.
Aesthetic Appeal and Design
Aesthetically, the Thermalright Assassin King 120 SE boasts colorful ARGB lighting, appealing to gamers and PC builders who prioritize visual customization. Its sleek white design complements many build themes. In contrast, the Phantom Spirit 120 EVO features a more refined, anodized black frosted finish that exudes elegance and sophistication.
