Overview of the Thermalright Peerless Assassin 120 SE and NZXT Kraken Plus 240
The Thermalright Peerless Assassin 120 SE is priced at £26.90, while the NZXT Kraken Plus 240 comes in at £97.97. This significant price difference sets the stage for a comparison of their performance and features. The Thermalright model is an air cooler designed for efficient heat dissipation, while the NZXT is a liquid cooler boasting advanced features aimed at high-performance cooling. Understanding these differences will help potential buyers make an informed decision based on their cooling needs and budget.
Cooling Performance
When it comes to cooling performance, the NZXT Kraken Plus 240 excels with its high-flow Turbine pump designed for efficient and low-noise operation. This model is particularly effective under heavy workloads, making it ideal for gamers and content creators who push their CPUs to the limit. In contrast, the Thermalright Peerless Assassin 120 SE utilises a double tower design with six heat pipes, which also provides strong cooling capabilities. However, its maximum fan speed of 1550 RPM and airflow of 66.17 CFM suggest it may not match the raw cooling power of liquid cooling systems like the Kraken Plus 240.
Noise Levels
Noise levels are an essential consideration for many users. The NZXT Kraken Plus 240 features a Zero RPM Mode that allows fans to stop completely during low loads, promoting silent operation. This feature can significantly enhance the user experience in quiet environments. Meanwhile, the Thermalright Peerless Assassin 120 SE operates at a noise level of ≤25.6 dB(A). While this is relatively quiet, it does not offer the same level of silent performance under varying loads as the NZXT, especially in scenarios where maximum cooling is required.
Installation Process
Installation ease is a crucial factor for many DIY PC builders. The NZXT Kraken Plus 240 is designed for quick setup, featuring pre-applied thermal paste and a single breakout cable, which helps reduce cable clutter. This streamlined installation process can save time and frustration. On the other hand, the Thermalright Peerless Assassin 120 SE comes equipped with metal fasteners for both Intel and AMD platforms, ensuring good compatibility. However, the installation may not be as straightforward as that of the NZXT, especially for those unfamiliar with air coolers.
Design and Aesthetics
Aesthetics play a significant role in PC builds, and the NZXT Kraken Plus 240 has a modern edge with its custom LCD screen. This feature allows users to display real-time system temperatures, animated GIFs, or custom images, adding a personal touch to the setup. In contrast, the Thermalright Peerless Assassin 120 SE has a more utilitarian design, focusing on functionality over flair. While it may lack the visual appeal of the NZXT, its robust build and double tower design may appeal to those prioritising performance over looks.
Compatibility
Both coolers offer wide compatibility with modern CPU sockets. The NZXT Kraken Plus 240 supports the latest AMD and Intel CPU sockets, including AM5 and LGA 1851. This ensures that it can easily fit into most contemporary builds. The Thermalright Peerless Assassin 120 SE is equally versatile, supporting a range of Intel sockets (LGA1150/1151/1155/1156/1200/1700/1851) and AMD sockets (AM4 AM5). This broad compatibility makes both options suitable for various builds, from budget systems to high-performance machines.
Brand Reputation
Brand reputation can impact purchasing decisions, and both Thermalright and NZXT have established themselves in the cooling market. Thermalright has over 20 years of experience, specialising in CPU air-cooling solutions and gaining a loyal following. Conversely, NZXT is known for its innovative designs and user-friendly products, making it a favourite among gamers and PC enthusiasts. The choice between these brands may come down to personal preference and past experiences with their products.
Price Consideration
The price difference between the two coolers is substantial, with the Thermalright Peerless Assassin 120 SE priced at £26.90 and the NZXT Kraken Plus 240 at £97.97. This significant variance may influence your decision, especially if you're on a budget. While the Thermalright offers solid performance for its price, the NZXT provides advanced features and superior cooling capabilities that may justify its higher cost for users needing top-tier performance.
Which should you buy?
Deciding between the Thermalright Peerless Assassin 120 SE and the NZXT Kraken Plus 240 hinges on your specific needs and budget. If you seek an affordable, reliable air cooler, the Thermalright is an excellent choice, offering strong cooling performance at a fraction of the price. However, if you require high-performance cooling for intensive tasks and value additional features like a custom LCD screen and silent operation, the NZXT Kraken Plus 240 is worth the investment. Ultimately, your decision will reflect your cooling requirements, aesthetic preferences, and financial considerations.
