Overview of the Thermalright Peerless Assassin 120 SE V2 and ASUS Prime LC 360 ARGB

The Thermalright Peerless Assassin 120 SE V2 is priced at C$54.90, while the ASUS Prime LC 360 ARGB is significantly more expensive at C$159.99. This price difference sets the stage for distinct market segments and user needs, with the Peerless Assassin catering to budget-conscious users seeking effective air cooling, and the ASUS Prime appealing to those who prefer liquid cooling solutions with advanced aesthetics.

The Thermalright Peerless Assassin offers a robust cooling performance with its 6 heat pipes and dual fans, while the ASUS Prime boasts a high-performance design with ARGB lighting and a 360mm radiator for superior heat dissipation. This article will delve into their features, ease of installation, performance, aesthetics, and overall value to help you decide which cooler best suits your needs.

Cooling Performance

Cooling performance is crucial for maintaining optimal CPU temperatures, and both the Thermalright Peerless Assassin and ASUS Prime LC 360 deliver in their respective ways. The Thermalright model features 6 heat pipes and a TDP of up to 265W, making it capable of handling high-performance CPUs effectively. Its dual 120mm PWM fans can reach a maximum airflow of 88.19 CFM at a noise level of 29.5 dB(A), ensuring efficient cooling during demanding tasks.

In contrast, the ASUS Prime LC 360 uses a larger 360mm radiator that enhances its cooling capabilities by allowing for greater heat dissipation. Though specific airflow ratings for its fans are not provided, the design suggests a strong emphasis on cooling efficiency, especially for overclocked systems. Overall, the ASUS Prime is likely to outperform the Thermalright in extreme scenarios due to its liquid cooling setup, but the latter still offers impressive cooling performance for its price range.

Installation and Compatibility

When it comes to installation, both coolers are designed for compatibility with a range of Intel and AMD sockets. The Thermalright Peerless Assassin includes metal fasteners for Intel LGA 1851/1700/1200/115X and AMD AM4/AM5 platforms, making it versatile for various builds. Its relatively compact size of 125mm x 135mm x 155mm allows it to fit comfortably in most cases.

The ASUS Prime LC 360, however, requires more consideration due to its size. With a larger 360mm radiator, it may not fit in smaller cases. Nonetheless, it is compatible with the same Intel and AMD platforms. The installation process for AIO liquid coolers can be more complex than air coolers, but the ASUS is designed for ease of use, often with pre-applied thermal paste and user-friendly mounting mechanisms. While both coolers are compatible across major platforms, the Peerless Assassin may be easier to install for users with limited experience.

Aesthetics and Design

The design of a CPU cooler can greatly influence the overall look of a PC build, and both the Thermalright Peerless Assassin and ASUS Prime LC 360 have unique aesthetics. The Thermalright features a classic design with an aluminum fin structure and a copper base, which appeals to users who prefer a straightforward, functional appearance.

In contrast, the ASUS Prime LC 360 excels in aesthetics with its futuristic look, highlighted by customizable infinity mirror lenses and ARGB lighting on its fans. This allows users to sync the cooler's lighting with other RGB components in their build, creating a cohesive and visually stunning setup. If aesthetics are a priority, the ASUS Prime clearly stands out with its modern design and lighting features.

Noise Levels

Noise levels can be a significant factor in choosing a CPU cooler, especially for users who value a quiet computing environment. The Thermalright Peerless Assassin operates at a maximum noise level of 29.5 dB(A), which is relatively quiet and suitable for most users. Its dual fans are designed to balance performance and sound, making it a good choice for those who prioritize silence.

On the other hand, while the ASUS Prime LC 360 does not specify its noise levels, liquid coolers generally operate quieter than their air counterparts under load. Users can expect the ASUS to maintain lower noise levels due to the liquid cooling system's efficiency. However, under heavy loads, the fans may ramp up, potentially producing more noise. In terms of noise performance, the Thermalright offers a concrete figure while the ASUS's performance remains more speculative.

Durability and Build Quality

Durability is essential for any cooling solution, and both the Thermalright Peerless Assassin and ASUS Prime LC 360 are built with quality materials. The Peerless Assassin features a combination of aluminum fins and a pure copper base, ensuring efficient heat transfer and long-lasting performance.

The ASUS Prime, with its reinforced, sleeved tubing, enhances durability, particularly in preventing wear and tear over time. Liquid coolers can be susceptible to leaks, but ASUS's design aims to mitigate this risk, offering peace of mind for users. Both coolers are built to last, but the ASUS's design may provide an edge in long-term reliability, particularly for those pushing their systems to the limit.

Price-to-Performance Ratio

Price is a significant consideration when comparing the Thermalright Peerless Assassin and the ASUS Prime LC 360. At C$54.90, the Thermalright offers excellent value for users seeking effective cooling without breaking the bank. Its performance metrics are impressive for the price, making it an ideal choice for budget builds or users who do not require extreme cooling.

In contrast, the ASUS Prime LC 360's price of C$159.99 reflects its advanced features, aesthetics, and superior cooling capabilities. For users looking for high performance and who are willing to invest more for liquid cooling and RGB aesthetics, the ASUS may justify its price. Ultimately, the best choice depends on your budget and specific cooling needs.

Which should you buy?

Deciding between the Thermalright Peerless Assassin 120 SE V2 and ASUS Prime LC 360 ARGB largely hinges on your cooling requirements, aesthetic preferences, and budget. If you're seeking a cost-effective air cooler that offers strong performance, the Thermalright is an excellent option. Conversely, if you're willing to invest more for superior cooling performance, aesthetics, and advanced features, the ASUS Prime is the clear choice. Each cooler has its strengths, making them suited to different user needs and preferences.
