Additionally, the Peerless cooler's dual-tower design, combined with its dual fans, allows for more effective heat dissipation. This results in a fan speed that, although lower at 1850 RPM compared to the Assassin X's 2000 RPM, still provides superior cooling due to its design and air volume. Therefore, for overclocking or high-performance CPUs, the Peerless model is the clear winner.
Noise Levels and Efficiency
When it comes to noise levels, the Assassin X 120R operates at a maximum of ≤ 29.8 dB(A), while the Peerless Assassin 120 is quieter, operating at ≤ 25.6 dB(A). Despite the lower fan speed of the Peerless model, its dual fans and advanced design contribute to more efficient cooling at lower noise levels. This makes the Peerless ideal for users who prefer a quieter computing environment without compromising on cooling performance. Thus, if noise is a critical factor in your selection, the Peerless Assassin 120 is the better option.
Size and Compatibility
The Thermalright Assassin X 120R has a height of 151mm, making it compatible with most cases, while the Peerless Assassin 120 stands slightly taller at 162mm. This size difference means that the Peerless may have compatibility issues with certain smaller cases. However, both coolers are designed to fit a wide range of Intel and AMD sockets, ensuring that they can accommodate a variety of builds. The slightly larger size of the Peerless model allows for better cooling potential but may require more consideration regarding case compatibility.
Aesthetics and Design Features
Visual appeal is an important consideration for many PC builders, and both coolers offer ARGB lighting features. The Assassin X 120R has a digital screen that enhances its aesthetic, combining performance with style. On the other hand, the Peerless Assassin 120 boasts a magnetic top cover that not only adds to its sleek design but also allows for easy access to the fans. The customizability of the ARGB lighting in both models will appeal to users looking to create a visually cohesive build. However, the unique magnetic cover design of the Peerless provides an innovative touch that may attract more attention.
Installation and User Experience
Both coolers come with installation accessories and are compatible with various Intel and AMD sockets, including Intel LGA 1851/1700/1150/1151/1155/1156/1200 and AMD AM4/AM5. The installation process for both models is user-friendly, with the Assassin X 120R providing a comprehensive manual and video guide. Meanwhile, the Peerless Assassin 120 includes similar instructions, ensuring a smooth setup.
