Overview of the Products
The Thermalright Peerless Assassin 120 Black CPU Air Cooler is priced at $38.90, while the Thermalright Phantom Spirit 120 EVO CPU Cooler costs $46.90, making the Peerless Assassin about 17% cheaper. Both coolers are designed to provide exceptional thermal performance for various Intel and AMD processors, but they differ in features, design, and cooling capabilities.
Design and Build Quality
In terms of design, the Thermalright Peerless Assassin features a sleek black aluminum heatsink cover with a twin-tower layout, while the Phantom Spirit boasts an anodic black frosted finish with a refined texture. Both coolers measure 125mm x 135mm x 157mm, ensuring they fit in most cases. The build quality of the Phantom Spirit is enhanced by its seven heat pipes, compared to the six in the Peerless Assassin, which could offer better heat transfer and cooling efficiency.
Cooling Performance
Cooling performance is vital for any CPU cooler, and both products deliver impressive results. The Peerless Assassin has a TDP of 245W and features dual TL-C12B PWM fans operating at 1500 RPM, providing an airflow of 66.17 CFM with a noise level of up to 25.6 dB(A). On the other hand, the Phantom Spirit pushes the envelope with a fan speed of 2150 RPM and an airflow of 69 CFM, albeit at a slightly higher noise level of 27 dB(A). Therefore, while the Peerless Assassin is quieter, the Phantom Spirit offers a higher cooling capacity, potentially making it more effective in demanding scenarios.
Compatibility
Both coolers are compatible with a wide range of CPU sockets. The Peerless Assassin supports Intel sockets LGA1150 through LGA2066 and AMD AM4/AM5, making it versatile for various builds. Similarly, the Phantom Spirit supports the same Intel and AMD sockets, ensuring broad compatibility. This means users can choose either cooler without worrying about socket compatibility for most modern processors.
Fan Technology
The fan technology in both coolers plays a crucial role in their overall performance. The Peerless Assassin employs dual PWM fans that are designed to provide a good balance between airflow and noise. In contrast, the Phantom Spirit’s fans operate at a higher RPM, which can lead to slightly noisier operation but also improved cooling performance. The choice between the two may come down to personal preference regarding noise levels versus raw cooling power.
Price Comparison
The Thermalright Peerless Assassin is priced at $38.90, while the Phantom Spirit stands at $46.90, representing a price difference of $8.00. This makes the Peerless Assassin a more budget-friendly option, especially for users who are looking for solid cooling performance without breaking the bank. However, the additional $8 for the Phantom Spirit may be justified for those who prioritize higher cooling capabilities.
Brand Reputation
Both products are manufactured by Thermalright, a brand known for its quality and performance in the cooling market. With over 20 years of experience, Thermalright has established a solid reputation among PC enthusiasts. The reputation of the brand can be an essential factor for consumers, as it often correlates with product reliability and customer service.
User Experience and Installation
Installation is a significant consideration for any CPU cooler, and both products come with the necessary mounting hardware for Intel and AMD platforms. The Peerless Assassin is designed with an offset asymmetric layout, allowing for easier installation without obstructing the first graphics card slot. The Phantom Spirit also provides detailed installation instructions, which can simplify the process for users. Feedback from users often highlights how straightforward the installation process is for both coolers.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Black and the Thermalright Phantom Spirit 120 EVO ultimately depends on your specific needs. If you’re looking for a more economical option with quieter operation, the Peerless Assassin is an excellent choice. However, if you require maximum cooling performance and don’t mind a little extra noise and cost, the Phantom Spirit is worth the investment. Both coolers offer compatibility and solid performance, making either a good addition to your build.
