Design and Aesthetics

The Thermalright Peerless Assassin 120 Vision MAX features a modern design with a striking 5-inch IPS LCD screen, while the Thermalright Assassin X120 Refined SE opts for a classic look. The LCD screen on the Peerless model enhances functionality by providing real-time monitoring of system parameters, making it not only a cooler but also a visual centerpiece in your setup. The Assassin X120, on the other hand, has a more straightforward aluminum heatsink cover that appeals to users who prefer a traditional aesthetic.

The contrast in designs illustrates the different target audiences: the Peerless is aimed at users who enjoy customization and visual flair, while the Assassin X120 caters to those who appreciate simplicity and efficiency.

Cooling Performance

When it comes to cooling efficiency, the Thermalright Peerless Assassin 120 Vision MAX outperforms the Assassin X120. The Peerless model operates at a fan speed of 2150 RPM, generating an airflow of 69 CFM, whereas the Assassin X120 runs at a lower speed of 1550 RPM with an airflow of 66.17 CFM. This translates to about 8% more airflow from the Peerless, which can lead to better thermal performance, particularly in high-load scenarios.

The dual-tower design of the Peerless enhances its cooling capability, making it suitable for overclocking and intense gaming sessions. In contrast, the Assassin X120 is adequate for regular use but may struggle under extreme conditions.

Noise Levels

The Thermalright Assassin X120 Refined SE boasts a maximum noise level of 25.6 dB(A), making it a quieter option compared to the Peerless, which has an operating noise level of 27 dB(A). While the difference is marginal, those particularly sensitive to noise may prefer the Assassin X120 for its quieter operation.

However, the difference in noise levels might not be significant enough to deter users from choosing the Peerless due to its superior cooling performance. Gamers and performance enthusiasts may find the slight increase in noise acceptable for the enhanced thermal management it offers.

Compatibility

Both coolers are designed to support a variety of CPU sockets, making them versatile options for different builds. The Thermalright Assassin X120 is compatible with Intel sockets 1150, 1151, 1155, 1200, 1700, and AMD AM4/AM5, covering a wide range of processors. The Thermalright Peerless Assassin 120 Vision MAX matches this compatibility with support for Intel LGA 1851, 1700, and 115x, as well as AMD AM4/AM5.

This similarity means that both coolers will fit well with most modern setups. The choice between them may therefore come down to performance and design preferences rather than compatibility concerns.

Installation Process

The installation of both coolers is straightforward, as they come equipped with necessary mounting hardware for both Intel and AMD platforms. The Thermalright Assassin X120 features metal fasteners designed for easy installation, while the Peerless Assassin offers a similar experience with its user-friendly design.

However, the Peerless may have a slight edge due to its dual-tower design, which is engineered for better clearance and compatibility with taller RAM heat spreaders. This consideration could simplify the installation process, especially in cases where space is a constraint.

Price Point

The Thermalright Assassin X120 is priced at $17.90, making it about 69% cheaper than the Thermalright Peerless Assassin 120 Vision MAX, which retails for $57.69. This significant price difference may attract budget-conscious buyers who still want reliable cooling performance without breaking the bank.

While the Peerless offers advanced features like the LCD screen and dual-tower design, the value proposition of the Assassin X120 cannot be overlooked, especially for those who prioritize cost over extra features.

Brand Reputation

Thermalright is a well-established brand in the CPU cooling market, with over 20 years of experience. Both products reflect the brand's commitment to quality and innovation. The reputation of Thermalright lends credibility to both coolers, ensuring that users can trust their performance.

While brand reputation is important, the choice between the two models ultimately comes down to individual needs and preferences. Users should consider what features they prioritize most in a CPU cooler.

Which should you buy?

The choice between the Thermalright Assassin X120 Refined SE and the Thermalright Peerless Assassin 120 Vision MAX boils down to your specific needs. If you are looking for a budget-friendly option with reliable performance, the Assassin X120 is an excellent choice at only $17.90. However, if you are willing to invest more for superior cooling performance and modern aesthetics, the Peerless Assassin at $57.69 offers better airflow and innovative features.

Ultimately, for gamers and performance enthusiasts, the extra investment in the Peerless model may be worthwhile for its enhanced cooling capabilities. However, for everyday users or those with budget constraints, the Assassin X120 remains a solid contender.
