Dimension comparison
Brand Overview
Both the Thermalright Phantom Spirit 120 EVO CPU Cooler and the Thermalright Peerless Assassin 140 Black CPU Cooler are produced by Thermalright, a well-established brand with over 20 years in the cooler market. This Taiwanese brand is known for its focus on the research and development of computer accessories, ensuring a solid reputation for quality and performance. The Phantom Spirit is priced at C$56.51, while the Peerless Assassin is slightly cheaper at C$54.90, making both options competitive in terms of affordability.
Cooling Performance
In terms of cooling performance, the Thermalright Peerless Assassin 140 Black boasts superior heat dissipation capabilities due to its twin-tower design and dual fans. With a maximum fan speed of 1500 RPM and dual configurations, it effectively disperses heat from the CPU across its large aluminum fins. Conversely, the Phantom Spirit 120 EVO features a single fan with a maximum speed of 2150 RPM, designed to drive heat effectively but with a smaller cooling surface area. While both coolers are efficient, the Peerless Assassin’s dual-fan system and larger dimensions suggest it may handle higher thermal loads better.
Design and Build Quality
When it comes to design, the Peerless Assassin 140 Black has a more robust build with its twin-tower structure and symmetrical mecha-shaped fins, measuring 140mm in length and 158mm in height. This design allows for an increased cooling surface area, which is beneficial for heat dissipation. In comparison, the Phantom Spirit 120 EVO has a more compact design at 125mm in length and 157mm in height, making it suitable for smaller cases. Both coolers are constructed from durable materials: the Phantom Spirit utilises aluminum and a finely crafted pure copper base, while the Peerless Assassin incorporates a pure copper base with aluminum fins, promoting longevity and performance.
Noise Levels
In terms of noise levels, the Thermalright Peerless Assassin 140 Black operates at a maximum noise level of 25.6 dB(A), which is relatively quiet and suitable for most users. The Phantom Spirit 120 EVO does not specify its noise levels, but with a higher fan speed of 2150 RPM, it could potentially produce more noise under load. For users who prioritise a silent operation, the Peerless Assassin may have the edge due to its dual fans operating at a lower RPM.
Installation and Compatibility
The installation process for both coolers is designed to be user-friendly. The Peerless Assassin 140 Black includes all-metal fasteners with a versatile SS2 buckle system, ensuring compatibility with a wide range of CPU models and making installation easier. The Phantom Spirit 120 EVO also features a Y-type adapter cable for fan connection, providing flexibility. Both coolers support various Intel and AMD sockets, but the Peerless Assassin's more comprehensive compatibility with high-profile memory and graphics cards can be advantageous for those with larger builds.
Aesthetic Appeal
Aesthetic design may also play a significant role in your decision. The Phantom Spirit 120 EVO features a stylish ARGB fan design, enhancing the visual appeal of a gaming rig. In contrast, the Peerless Assassin 140 Black, while functional, has a more utilitarian appearance with its twin-tower layout. If aesthetics are crucial for your build, the Phantom Spirit may offer a more visually striking option, especially with its customizable lighting features.
Price Consideration
Price is an important factor when comparing these two coolers. The Thermalright Phantom Spirit 120 EVO is priced at C$56.51, slightly higher than the Peerless Assassin 140 Black, which is available for C$54.90. While the price difference is minimal, the value offered by each cooler in terms of performance and features should be considered. The Peerless Assassin, with its superior cooling capability and dual fans, may justify its price in terms of performance, while the Phantom Spirit's aesthetic and compact design may appeal to different user preferences.
Which should you buy?
Ultimately, the decision between the Thermalright Phantom Spirit 120 EVO and the Thermalright Peerless Assassin 140 Black hinges on your specific needs and preferences. If you prioritise superior cooling performance and a larger heat dissipation area, the Peerless Assassin is the better choice, especially given its dual-fan configuration and effective heat management features. However, if aesthetics, a slightly smaller footprint, and a higher fan speed appeal to you, the Phantom Spirit 120 EVO offers a compelling option. Both coolers are well-made and cater to different segments of the market, ensuring that users can find a product that fits their unique requirements.
