Dimension comparison
Price Comparison
The Thermalright Assassin X 120 SE CPU Air Cooler is significantly more affordable than the CPU Cooler Wraith Prism, priced at C$25.59 compared to C$40.99. This difference of C$15.40 makes the Thermalright a more budget-friendly option for those looking to upgrade their cooling system without overspending. The pricing reflects the brands' positioning in the market, with Thermalright being a well-established name in CPU cooling solutions for over 20 years. On the other hand, the Wraith Prism targets users who may be willing to pay a premium for aesthetics and additional features like RGB lighting.
Design and Build Quality
The Thermalright Assassin X 120 SE features a robust design with an aluminum heat sink complemented by metal fasteners suitable for both Intel and AMD platforms. In contrast, the CPU Cooler Wraith Prism also has an aluminum heatsink but is enhanced with a copper core and copper heat pipes, which may provide better thermal conductivity. The choice of materials in both products indicates a focus on durability and performance, but the Wraith Prism's copper core could offer improved heat dissipation capabilities. The Assassin X measures 125mm in length and 148mm in height, making it suitable for medium-sized cases, while the Wraith Prism is designed to fit a broader range of AMD sockets with a pre-installed bracket, simplifying installation.
Cooling Performance
The Thermalright Assassin X 120 SE boasts a maximum airflow of 66.17 CFM and operates at a noise level of 25.6 dB(A), delivering effective cooling while maintaining a quiet environment. Its PWM fan operates at a maximum speed of 1550 RPM, striking a balance between performance and noise. The Wraith Prism, on the other hand, features a 95mm fan capable of speeds ranging from 3000 RPM to 3600 RPM. This higher RPM range suggests that the Wraith Prism could potentially offer superior cooling performance, especially under high-load conditions, although it might come with increased noise levels given the higher speeds.
Compatibility
The Thermalright Assassin X 120 SE has broad compatibility, supporting multiple Intel socket types (115X/1200/1700/17XX) and AMD's AM4 socket. This wide array of supported sockets makes it versatile for various builds. The Wraith Prism is compatible with an even wider range of AMD sockets, including AM5, AM4, AM3, AM2, FM2, and several others, making it an excellent choice for users with older systems. However, it does not support Intel sockets, which could limit its appeal to users with mixed-platform setups.
Installation Process
The installation process for the Thermalright Assassin X 120 SE is straightforward, as it comes with metal fasteners designed for both Intel and AMD platforms. This makes it easier for users to install without needing additional mounting kits. The Wraith Prism also simplifies installation with its standard bracket, which is pre-installed on most motherboards. However, it does not come with a cooler, which could be a downside for those who prefer a complete package. This consideration may affect the overall user experience during installation.
Aesthetics and Features
In terms of aesthetics, the Wraith Prism has a distinct advantage with its RGB LED lighting, allowing users to customize their build's look. This feature can enhance the overall visual appeal of a gaming rig or high-performance workstation. The Thermalright Assassin X 120 SE, while effective, does not include RGB features, focusing instead on performance and practicality. If visual customization is a priority, the Wraith Prism may be the preferred choice despite its higher price point.
Noise Levels
When it comes to noise levels, the Thermalright Assassin X 120 SE operates at a maximum of 25.6 dB(A), which is relatively quiet and ideal for users who prioritize a silent working environment. In contrast, the Wraith Prism’s fan speed can reach up to 3600 RPM, which may result in louder operation, especially under heavy loads. While both coolers are designed to manage temperatures effectively, the Thermalright Assassin X is likely to be the quieter option, making it suitable for users who work in noise-sensitive environments.
Which should you buy?
Choosing between the Thermalright Assassin X 120 SE and the CPU Cooler Wraith Prism depends on your specific needs and preferences. The Thermalright Assassin X is a budget-friendly cooler with great performance and low noise levels, making it an excellent choice for general users and those with a focus on quiet operation. On the other hand, the Wraith Prism offers superior compatibility with AMD sockets, enhanced cooling potential, and aesthetic features like RGB lighting, making it ideal for gamers and users looking to build visually appealing systems. Ultimately, if performance and price are your main concerns, the Thermalright Assassin X is the winner; however, if you prioritise aesthetics and compatibility with AMD systems, the Wraith Prism may be worth the extra investment.
