Overview of the Thermalright Peerless Assassin 140 Black and ASUS Prime LC 360 ARGB
When it comes to CPU cooling, both the Thermalright Peerless Assassin 140 Black and the ASUS Prime LC 360 ARGB offer distinct advantages tailored to different user needs. The Peerless Assassin is a tower cooler priced at C$54.90, while the ASUS Prime LC 360 ARGB is an all-in-one liquid cooler available for C$159.99. Understanding their unique features can help you make an informed decision based on your cooling requirements and budget.
Cooling Performance
The cooling performance of both products is a significant factor to consider. The Thermalright Peerless Assassin features a twin-tower design with pure copper heat pipes and dual PWM fans that can reach a speed of 1500 RPM. This configuration allows for effective heat dissipation, with a maximum air volume of 66.17 CFM. In contrast, the ASUS Prime LC 360 ARGB is equipped with a specially designed CPU contact area that enhances heat dissipation and comes with high-performance ARGB fans. While both coolers provide excellent cooling capabilities, the Peerless Assassin is built with a more traditional air cooling approach, whereas the ASUS model leverages liquid cooling technology, which can typically offer superior performance in demanding scenarios.
Installation Process
Installation is another critical aspect where both coolers differ significantly. The Thermalright Peerless Assassin is compatible with a wide range of CPU sockets, including Intel’s LGA1150 to LGA1851 and AMD’s AM4 and AM5. Its design features all-metal fasteners and a user-friendly installation process. On the other hand, the ASUS Prime LC 360 ARGB is also compatible with AMD (AM4 and AM5) and Intel (LGA) sockets, but its all-in-one liquid cooling setup may require more careful handling during installation due to the need for mounting the radiator. While both coolers offer straightforward installation, the Peerless Assassin may be more accessible for users who prefer a traditional air cooler.
Aesthetic Appeal
The aesthetic features of the coolers present another point of comparison. The ASUS Prime LC 360 ARGB stands out with futuristic aesthetics, including customizable infinity mirror lenses that can enhance the look of your build, especially for gamers or those who appreciate RGB lighting. In contrast, the Thermalright Peerless Assassin, while functional and effective, does not offer the same level of visual flair. Its design is more utilitarian, focusing on performance rather than aesthetics. If you value visual appeal in your PC build, the ASUS cooler is the clear winner.
Noise Levels
Noise levels are a crucial consideration for users who desire a quiet computing experience. The Thermalright Peerless Assassin operates at a noise level of ≤25.6 dB, which is relatively quiet for a dual-fan air cooler. The ASUS Prime LC 360 ARGB does not specify its noise levels, but liquid coolers generally operate more quietly than their air counterparts due to the absence of high-speed fans. However, the lack of a defined noise metric makes it difficult to compare directly. If minimal noise is a priority, the Peerless Assassin provides a concrete specification to consider.
Price and Value
Price is often a decisive factor when selecting a CPU cooler. The Thermalright Peerless Assassin is priced at a budget-friendly C$54.90, making it an attractive option for those looking for effective cooling without breaking the bank. Conversely, the ASUS Prime LC 360 ARGB, at C$159.99, is significantly more expensive but offers advanced features like liquid cooling and aesthetic customization. Evaluating the value of each cooler depends on your specific cooling needs and budget; the Peerless Assassin offers excellent performance for its price, while the ASUS model provides additional features that justify its higher cost.
Compatibility
Compatibility is another area where both coolers excel. The Thermalright Peerless Assassin supports a wide range of CPU sockets, making it versatile for various builds. It is compatible with several Intel and AMD sockets, ensuring that most users can use it without issues. The ASUS Prime LC 360 ARGB also supports the latest AMD and Intel sockets, making it equally versatile. However, users should consider their specific motherboard and case dimensions, particularly with the larger radiator required for the ASUS cooler. Both options provide solid compatibility, but installation space and system requirements should be factored in.
Which should you buy?
Deciding between the Thermalright Peerless Assassin 140 Black and the ASUS Prime LC 360 ARGB ultimately comes down to your individual needs and preferences. If you are looking for an effective, budget-friendly air cooler with solid performance and lower noise levels, the Thermalright Peerless Assassin at C$54.90 is a great choice. However, if you prioritize aesthetics, advanced cooling performance, and are willing to invest more for liquid cooling technology, the ASUS Prime LC 360 ARGB at C$159.99 may be the better option. Each cooler excels in its respective category, so consider what features matter most to you before making a purchase.
