Overview of the Coolers
The Thermalright Peerless Assassin 120 Mini Black CPU Cooler is priced at $34.39, while the Thermalright Phantom Spirit 120 SE Black CPU Cooler costs $39.90. This makes the Peerless Assassin approximately 17% cheaper than the Phantom Spirit. Both coolers are designed for high-performance cooling, making them suitable for various Intel and AMD CPUs, but they employ different technologies and designs in their construction.
Design and Aesthetics
The Peerless Assassin features a fully blackened design with an antioxidant coating and CNC precision micro-engraved copper base. Its compact size of 125mm x 110mm x 135mm allows it to fit into smaller cases without sacrificing performance. On the other hand, the Phantom Spirit stands taller at 125mm x 135mm x 154mm and adopts a dual-tower design with an anodized black frosted finish. This not only enhances its aesthetic appeal but also increases the effective heat dissipation area. Both coolers have a sleek look, but the Phantom Spirit's design may attract users looking for a more robust and visually impactful cooler.
Cooling Performance
The cooling performance of the Peerless Assassin is driven by its six 6mm heat pipes and a 120mm PWM fan that operates at 1500 RPM, providing airflow of 66.87 CFM with a noise level of 25.6 dB(A). In contrast, the Phantom Spirit incorporates seven 6mm heat pipes and dual TL-C12B V2 PWM fans that also spin at 1500 RPM but slightly lower airflow at 66.17 CFM. While both coolers utilize AGHP technology to combat the inverse gravity effect, the additional heat pipe in the Phantom Spirit may offer marginally better thermal performance, especially during heavy loads.
Noise Levels
Both coolers operate at a comparable noise level of 25.6 dB(A), which is relatively quiet for CPU coolers. This ensures that users will not experience excessive noise during operation, making both options suitable for quiet builds. The use of S-FDB bearings in both models contributes to their longevity, boasting an industrial life of up to 20,000 hours. Therefore, noise levels are not a differentiating factor between the two coolers; both perform admirably in this category.
Installation and Compatibility
The Peerless Assassin is designed to support a wide range of CPU socket types, including Intel's LGA1150, LGA1151, LGA1200, and AMD's AM4 and AM5. Its installation kit comes with the necessary mounting plates and instructions for various platforms. The Phantom Spirit also supports the same socket types and includes similar mounting hardware. However, it is noted that AMD installations require the use of the original motherboard backplane, which could complicate the installation for some users. Overall, both coolers provide solid compatibility but may differ slightly in installation ease.
Durability and Build Quality
Both coolers emphasize durability through high-quality materials. The Peerless Assassin is constructed with aluminum and features a fully plated heat pipe for effective heat dissipation. The Phantom Spirit, however, utilizes an advanced soldering process and high-grade PBT + PC materials, which may provide a more robust build. The blackened nano coating on the Phantom Spirit adds extra protection against wear. While both coolers are built to last, the Phantom Spirit's construction may offer slightly better resilience over time.
Price and Value
At $34.39, the Peerless Assassin provides excellent value for budget-conscious consumers who still want solid cooling performance. In contrast, the Phantom Spirit is priced at $39.90, which reflects its additional features, such as dual fans and a taller design. The price difference of about $5.51 could be justified for users seeking enhanced cooling capabilities and aesthetics. However, budget-minded users may find the Peerless Assassin to be a more attractive option without sacrificing too much performance.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Mini Black and the Thermalright Phantom Spirit 120 SE Black ultimately depends on your specific needs and preferences. If you're looking for a more affordable option that still delivers solid performance, the Peerless Assassin is a great choice at $34.39. However, if aesthetics, dual-fan cooling, and slightly improved thermal performance are more important to you, the Phantom Spirit at $39.90 may be worth the extra investment. Both coolers are capable, but your decision should hinge on your budget and cooling requirements.
