Dimension comparison
Overview of the Products
The Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler is priced at $45.90, while the Thermalright Phantom Spirit 120SE CPU Air Cooler comes in at $35.90, making it about 17% cheaper. Both products are designed to provide efficient cooling for various CPU platforms, including AMD and Intel. The Peerless Assassin features a digital screen and multiple heat pipes, while the Phantom Spirit boasts a more traditional design with a focus on heat dissipation through its aluminum fins and copper base.
Design and Aesthetics
The design of the Thermalright Peerless Assassin stands out with its digital screen on the top cover, offering a modern touch to your PC setup. Its dual-tower structure is complemented by six heat pipes, enhancing its cooling performance. In contrast, the Thermalright Phantom Spirit features a more understated aluminum body with a black frosted finish and finely carved copper base, which appeals to users looking for a sleek and professional look. While both coolers are visually appealing, the choice may come down to whether you prefer flashy aesthetics or a minimalist design.
Cooling Performance
Cooling performance is critical for any CPU cooler, and both the Peerless Assassin and Phantom Spirit excel in this area. The Peerless Assassin utilizes six heat pipes and operates at a fan speed of up to 1850 RPM, generating an airflow of 88.89 CFM. This high airflow rate is designed to effectively dissipate heat from your CPU, ensuring it remains cool even under heavy loads. The Phantom Spirit, on the other hand, is equipped with seven heat pipes and operates at a slightly lower fan speed of 1500 RPM, delivering an airflow of 66.17 CFM. While both offer excellent cooling, the Peerless Assassin provides a higher airflow and RPM, making it potentially more effective for overclocking enthusiasts.
Noise Levels
In terms of noise levels, both coolers are designed to operate quietly, with the Peerless Assassin rated at a maximum noise level of 25.6 dB(A) and the Phantom Spirit boasting a similar noise level. This means users can expect a quiet computing experience from either cooler, as both are engineered to minimize sound output while maintaining performance. However, the Peerless Assassin's higher fan speed may lead to slightly more noise under load, although both options are relatively silent compared to other models on the market.
Compatibility
Both the Thermalright Peerless Assassin and Phantom Spirit offer wide compatibility with various CPU socket types. The Peerless Assassin supports AMD AM4/AM5 and Intel LGA1700/1851/1150/1151/1155/1156/1200, while the Phantom Spirit supports similar platforms, including AM4/AM5 and Intel LGA1851/1700/1150/1151/1155/1156/1200. This compatibility ensures that both coolers can be installed on most modern builds, making them versatile choices for users upgrading their systems. The inclusion of mounting clips for both coolers simplifies installation, catering to both novice and experienced builders.
Installation Process
The installation process for both the Peerless Assassin and Phantom Spirit is designed to be user-friendly. Each cooler comes with the necessary mounting hardware and installation instructions, making it accessible for all users. The Peerless Assassin, with its dual-tower design, may require a bit more effort to ensure proper alignment and clearance within the case, especially with high-capacity memory modules. The Phantom Spirit, being slightly shorter at 154mm in height compared to the Peerless Assassin's 162mm, may fit more easily into tighter spaces. This can be an important consideration for users with compact builds.
Price Consideration
The Thermalright Peerless Assassin is priced at $45.90, whereas the Phantom Spirit is more budget-friendly at $35.90. This $10 difference can be significant for those on a tighter budget, representing about a 17% savings with the Phantom Spirit. Both products offer excellent value for their performance, but if budget constraints are a primary concern, the Phantom Spirit may be the more attractive option without sacrificing too much in terms of cooling efficiency.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler and the Thermalright Phantom Spirit 120SE CPU Air Cooler ultimately depends on your specific needs and preferences. If you prioritize aesthetics and slightly better cooling performance, the Peerless Assassin is the way to go, despite its higher price. However, if you're looking for a cost-effective cooling solution that still delivers solid performance, the Phantom Spirit is an excellent choice, especially for standard builds. Ultimately, both coolers are reliable options, but the decision hinges on whether you value premium features or budget-friendly functionality more.
