Dimension comparison
Price Comparison
When considering price, the Thermalright Peerless Assassin 120 SE CPU Cooler is slightly more expensive at C$48.90 compared to the Thermalright Phantom Spirit 120 SE Black CPU Air Cooler, which retails for C$46.71. This difference of C$2.19 may seem minor, but it can influence budget-conscious buyers. Both coolers are priced competitively in the Canadian market, reflecting their quality and performance. Ultimately, the choice of cooler may come down to the specific features and performance each offers rather than just the price.
Design and Aesthetics
In terms of design, the Thermalright Peerless Assassin 120 SE boasts a dual tower heatsink configuration, which not only enhances its aesthetic appeal but also maximizes heat dissipation. It features beautiful ARGB lighting effects that can add flair to any build. Conversely, the Thermalright Phantom Spirit 120 SE Black has a more understated look with its blackened nano coating and anodized black frosted top. This design prioritizes a sleek, minimalist appearance while still providing excellent functionality. The choice between the two designs will depend on personal preference for either a vibrant or a more subtle aesthetic.
Cooling Performance
Cooling performance is critical for any CPU cooler, and both models excel in this regard. The Peerless Assassin 120 SE is equipped with six 6mm heat pipes using AGHP technology, which enhances heat exchange efficiency. With dual high airflow fans that achieve a maximum airflow of 66.17 CFM and a noise level of 25.6 dB(A), it balances performance and sound levels well. The Phantom Spirit 120 SE, however, features seven 6mm heat pipes with an upgraded AGHP technology, ensuring effective heat dissipation and a service life of up to 20,000 hours. The combination of a finely carved copper base and an all-aluminium fin design suggests a strong focus on maximizing cooling performance, making it a formidable competitor.
Compatibility
Compatibility is an essential factor for any CPU cooler. The Thermalright Peerless Assassin 120 SE supports a wide range of Intel sockets, including LGA1150 through LGA1851, as well as AMD AM4 and AM5. However, it requires the original motherboard’s backplate for AMD installations, which is not included. On the other hand, the Phantom Spirit 120 SE Black also accommodates a similar range of Intel and AMD sockets, making it equally versatile. Both coolers are designed to fit most modern builds, but users should ensure compatibility with their specific motherboards before making a purchase.
Installation Process
The installation process can vary between CPU coolers, and both models aim to simplify this for users. The Peerless Assassin 120 SE utilizes an SS2 install system, which is intended for ease of installation. It also comes with a metal pressure plate on the heatsink for improved contact with the CPU. The Phantom Spirit 120 SE, meanwhile, provides corresponding mounting plates and fasteners for different CPU socket types, along with installation instructions that can be followed easily. Both coolers are designed to facilitate a straightforward setup process, but the Peerless Assassin's dedicated install system may appeal more to less experienced builders.
Noise Levels
Noise levels can significantly impact user experience, especially in a quiet environment. The Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a cooler of its performance caliber. This makes it suitable for gaming or working in silence. The Phantom Spirit 120 SE, while not specifying a decibel level, is designed with S-FDB bearings that promise a long service life and potentially quieter operation. Users who prioritize silence might gravitate towards the Peerless Assassin, given its explicit noise rating.
Durability and Lifespan
Durability is a key consideration when investing in a CPU cooler. The Peerless Assassin 120 SE is built with a robust aluminum and copper construction, designed to withstand the rigours of continuous operation. Its heat pipes are soldered onto a copper base, enhancing longevity. The Phantom Spirit 120 SE stands out with its mention of an industrial service life of up to 20,000 hours, bolstered by high-quality materials like PBT + PC for strength. Both coolers are built to last, but the Phantom Spirit's emphasis on longevity may provide added peace of mind for buyers seeking durability.
Which should you buy?
Ultimately, the choice between the Thermalright Peerless Assassin 120 SE and the Thermalright Phantom Spirit 120 SE Black comes down to individual preferences and specific needs. If aesthetic appeal and slightly better cooling performance are top priorities, the Peerless Assassin may be the better choice. However, if durability and a more understated design are more appealing, the Phantom Spirit presents a compelling alternative. Both coolers have their strengths, and either can provide excellent cooling performance for a variety of builds.
