Introduction to the Comparison
When selecting a CPU cooler, cooling efficiency, compatibility, and aesthetics play significant roles. In this article, we will compare the Thermalright Peerless Assassin 120 SE CPU Cooler and the CPU Cooler Wraith Prism RGB LED Lighting. Priced at C$48.90 and C$40.99 respectively, each offers unique features aimed at different user needs and preferences.
Design and Build Quality
The Thermalright Peerless Assassin 120 SE features a dual tower heatsink made from aluminum and copper, providing a robust and efficient cooling solution. Its dimensions are 125mm x 135mm x 155mm, which allows for a significant heat exchange surface area. In contrast, the Wraith Prism employs an aluminum heatsink with a copper core, but its design is simpler. While the Peerless Assassin is built for high performance with six 6mm heat pipes, the Wraith Prism utilizes a single 95mm RGB fan that offers a maximum rotational speed of 3600 RPM. This indicates that the Peerless Assassin is likely to handle higher thermal loads more effectively.
Cooling Performance
Cooling performance is crucial, especially when overclocking or under heavy workloads. The Thermalright Peerless Assassin 120 SE is equipped with two high-performance ARGB fans that deliver a rated airflow of 66.17 CFM and operate at a fan speed of 1550 RPM. In comparison, the Wraith Prism’s fan can switch between 3000 RPM and 3600 RPM, providing flexibility in cooling performance. However, the overall airflow capability of the Wraith Prism is not specified, which leaves some uncertainty about its comparative efficiency. The Peerless Assassin is designed with six heat pipes to facilitate rapid heat exchange, potentially giving it an edge in sustained thermal performance.
Aesthetics and RGB Features
Aesthetics are an important consideration for many PC builders. The Thermalright Peerless Assassin 120 SE features colorful ARGB light effects that enhance its visual appeal, making it an attractive choice for those who enjoy RGB lighting. The Wraith Prism also includes RGB LED lighting, controlled via a USB header cable, allowing for programmable effects when paired with compatible motherboards. While both coolers offer appealing designs, the more comprehensive RGB capabilities of the Wraith Prism may cater to users looking for extensive customisation options.
Compatibility
Compatibility with various CPU sockets is essential for ensuring a hassle-free installation. The Thermalright Peerless Assassin 120 SE supports a wide range of Intel sockets, including LGA 1150, 1151, 1155, 1156, 1200, 1700, and AMD AM4/AM5. However, it requires the original motherboard's backplate for installation on AM4 and AM5, which some users may find inconvenient. On the other hand, the Wraith Prism is compatible with numerous AMD socket types, including AM5, AM4, AM3, AM2, and others. Its compatibility with standard brackets pre-installed on most motherboards makes it easier to install without additional components.
Noise Levels
Noise levels are an important factor to consider when selecting a CPU cooler, as a quieter operation enhances the overall user experience. The Thermalright Peerless Assassin 120 SE has a rated noise level of ≤25.6 dB(A), which indicates a relatively quiet operation during use. Conversely, while the Wraith Prism does not specify its noise levels, the higher maximum RPM of its fan (3600 RPM) may suggest that it could produce more noise under load. Users prioritizing a quiet computing environment may prefer the Peerless Assassin based on its lower noise rating.
Price and Value
The Thermalright Peerless Assassin 120 SE is priced at C$48.90, while the Wraith Prism is slightly more affordable at C$40.99. The price difference of C$7.91 reflects the differences in build quality, cooling performance, and features. The Peerless Assassin offers a dual-tower design, superior airflow, and a quieter operation, which may justify its higher price for users who require top-tier cooling performance. On the other hand, the Wraith Prism provides a solid option for budget-conscious buyers who still desire decent performance and RGB features.
User Experience and Installation
User experience includes not only product performance but also installation ease. The installation of the Thermalright Peerless Assassin 120 SE might require additional attention due to the need for the original motherboard's backplate for AMD installations. In contrast, the Wraith Prism’s compatibility with standard pre-installed motherboard brackets could facilitate a more straightforward setup process. Users who value quick and easy installation may find the Wraith Prism more appealing, despite its potentially lower cooling performance.
Which should you buy?
In determining which CPU cooler to purchase, consider your specific needs. If you seek superior cooling performance, quieter operation, and extensive compatibility with various Intel sockets, the Thermalright Peerless Assassin 120 SE is the better choice at C$48.90. However, if budget constraints and ease of installation are more critical, the CPU Cooler Wraith Prism at C$40.99 offers adequate performance and appealing RGB features. Ultimately, your decision should align with your performance requirements, aesthetic preferences, and budget considerations.
