Dimension comparison
Brand Overview
Both the Thermalright Peerless Assassin 120 SE CPU Cooler and the Thermalright Phantom Spirit 120 CPU Cooler come from the same reputable brand, Thermalright, which boasts over 20 years of experience in the computer cooling market. This longevity suggests a strong commitment to quality and innovation in their product lines. Thermalright is well-regarded for its extensive range of cooling solutions, including CPU coolers, case fans, and thermal accessories, ensuring you are choosing from a trusted manufacturer.
Design and Build Quality
The Thermalright Peerless Assassin 120 SE features dimensions of 125mm x 135mm x 155mm and incorporates a dual-tower heatsink configuration, maximizing heat exchange surface area. It is crafted from a combination of aluminum and copper, which enhances thermal conductivity. In contrast, the Thermalright Phantom Spirit 120 measures slightly taller at 125mm x 135mm x 157mm and is primarily constructed with aluminum, featuring a finely carved pure copper base. While both coolers demonstrate solid build quality, the Peerless Assassin's dual-tower design may offer superior cooling performance due to its increased surface area.
Cooling Performance
Cooling performance is essential for any CPU cooler, and both products deliver impressive results. The Peerless Assassin is equipped with two high-performance ARGB fans that can reach a fan speed of 1550 RPM, generating a maximum airflow of 66.17 CFM while maintaining a noise level of ≤25.6 dB(A). The Phantom Spirit, on the other hand, benefits from its upgraded AGHP technology with seven 6mm heatpipes, designed to enhance heat dissipation. Although specific airflow figures for the Phantom Spirit are not provided, its construction suggests that it also aims for high efficiency. The Peerless Assassin appears to have a slight edge in terms of airflow capabilities.
Compatibility
Both coolers boast extensive compatibility with various CPU socket types. The Peerless Assassin supports Intel sockets LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1851, along with AMD sockets AM4 and AM5. However, installation on AMD sockets requires the use of the motherboard's built-in backplate, which is not included. The Phantom Spirit matches this compatibility, supporting Intel LGA 1700, 1150, 1151, 1155, 1156, 1200, 2011, 2066, and AMD AM4 and AM5. Both coolers are well-suited for a wide range of systems, making them versatile options for different builds.
Noise Levels
The noise levels of CPU coolers can significantly impact user experience, especially in quiet environments. The Thermalright Peerless Assassin operates at a maximum noise level of ≤25.6 dB(A), which is relatively quiet for a high-performance cooler. The specifics regarding the Phantom Spirit's noise levels are not mentioned, but the use of Stably-FDB bearings suggests a focus on minimizing noise during operation. While the Peerless Assassin provides a quantifiable noise level, the Phantom Spirit's performance in this regard remains uncertain.
Aesthetics and Lighting
Aesthetic appeal is becoming increasingly important for many PC builders, and both coolers offer distinct design elements. The Peerless Assassin features colorful ARGB light effects that can enhance the visual appeal of any build. This cooler's design caters to those who appreciate customizable lighting. In comparison, the Phantom Spirit presents a more understated look with its anodized black frosted top. While it lacks ARGB lighting, its sleek design may appeal to users who prefer a more minimalist aesthetic. Ultimately, the choice between vibrant lighting and subtle elegance depends on personal preference.
Price and Value
When it comes to pricing, the Thermalright Peerless Assassin 120 SE is available for C$48.90, while the Thermalright Phantom Spirit 120 is slightly less expensive at C$47.90. The difference of just C$1 suggests that both options are competitively priced within the market. Given their comparable features and performance capabilities, the value proposition for each cooler is strong. However, potential buyers may consider additional factors such as aesthetics and cooling performance when determining which cooler offers the best value for their specific needs.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE and the Thermalright Phantom Spirit 120 ultimately depends on your specific requirements and preferences. If superior cooling performance and vibrant aesthetics are your priorities, the Peerless Assassin, with its dual-tower design and ARGB lighting, may be the better option. However, if you prefer a more minimalistic design and slightly lower pricing, the Phantom Spirit remains a robust choice. Both coolers offer excellent compatibility and are backed by a reputable brand, making either option a solid investment for your cooling needs.
