Cooling Performance Comparison
The cooling performance of the Thermalright Peerless Assassin 120 Vision MAX is superior due to its dual-tower design and higher fan speed of 2150 RPM, compared to the Assassin X 120R SE V2's 1550 RPM. The Peerless model offers an airflow of 69 CFM, while the Assassin X provides a maximum airflow of 66.17 CFM. This translates to a noticeable difference in cooling efficiency, especially for high-performance CPUs during intensive tasks.
Additionally, the Peerless cooler's six heat pipes and nickel-plated copper base enhance thermal conductivity, making it more effective at dissipating heat. The notable noise level of both coolers shows that the Assassin X operates slightly quieter at 25.6 dB(A) compared to the Peerless at 27 dB(A), but the cooling performance of the latter may justify the slight increase in operational noise.
Design and Aesthetics
When it comes to design, the Thermalright Peerless Assassin 120 Vision MAX stands out with its modern aesthetic, featuring a magnetic top cover that houses a vibrant 5-inch LCD screen. This display not only enhances the visual appeal but also allows users to monitor system parameters in real time, which is a significant advantage for tech enthusiasts.
In contrast, the Assassin X 120R SE V2 has a more straightforward design, focusing on functionality rather than flashy features. Its RGB PWM fan offers some customization for lighting, but it lacks the interactive display found in the Peerless model. Users looking for a cooler that combines performance with aesthetics may prefer the Peerless, while those seeking a more minimalistic approach may lean toward the Assassin X.
Installation and Compatibility
Both coolers are designed for easy installation and support a wide range of CPU sockets. The Thermalright Assassin X 120R SE V2 offers compatibility with Intel's LGA1150/1151/1155/1156/1200/1700/1851 and AMD's AM4/AM5 sockets. Similarly, the Peerless model supports the same socket types, ensuring that users can install either cooler on a variety of builds.
The Assassin X cooler has a height of 148mm, making it suitable for medium-sized cases, while the Peerless is slightly taller at 164mm, designed for standard ATX cases. Both coolers come with the necessary mounting hardware, and their installation processes are straightforward, appealing to both novice and experienced builders.
Noise Levels
In terms of noise levels, the Thermalright Assassin X 120R SE V2 operates at a quieter 25.6 dB(A), making it an excellent choice for users who prioritize a silent computing experience. The Peerless Assassin, while still relatively quiet at 27 dB(A), produces slightly more noise due to its higher RPM and dual-fan design.
For users who plan to run their systems under heavy loads, the additional cooling performance of the Peerless may outweigh the marginal increase in noise. However, for casual users or those with quieter setups, the Assassin X may be preferable for its quieter operation.
Price Comparison
The price difference between the two coolers is quite significant. The Thermalright Assassin X 120R SE V2 is priced at $16.59, making it about 71% cheaper than the Thermalright Peerless Assassin 120 Vision MAX, which costs $57.69.
