Price Comparison
When comparing the prices of the Thermalright Peerless Assassin 120 SE CPU Cooler and the Thermalright Aqua Elite 120 V3 Liquid CPU Cooler, the Aqua Elite is the more affordable option at C$41.75, while the Peerless Assassin is priced at C$48.90. This represents a difference of C$7.15, making the Aqua Elite a more budget-friendly choice for those looking to upgrade their cooling solution without breaking the bank. Both products offer excellent performance, but for users who are price-sensitive, the Aqua Elite may be the more appealing option.
Cooling Performance
In terms of cooling performance, the Thermalright Peerless Assassin 120 SE features a dual tower heatsink configuration combined with six 6mm heat pipes. This setup allows for efficient heat dissipation and effective thermal management, which is crucial for high-performance CPUs. The cooler is designed to achieve a maximum airflow of 66.17 CFM with its dual ARGB fans operating at 1550 RPM. On the other hand, the Thermalright Aqua Elite 120 V3 employs a liquid cooling system that includes a fourth generation pump head and a black aluminium fin heat sink. This configuration also offers a maximum airflow of 66.17 CFM, but with a slightly lower fan speed of 1500 RPM. While both coolers provide commendable cooling capabilities, the Peerless Assassin's design may give it an edge in certain high-load scenarios.
Build Quality and Materials
The build quality of both coolers reflects Thermalright's commitment to performance and durability. The Peerless Assassin is constructed with an aluminium and copper heat sink, ensuring robust thermal conductivity and longevity. Its design includes a metal pressure plate and a user-friendly SS2 installation system, which enhances compatibility with various CPU sockets. Conversely, the Aqua Elite features a protective mesh water pipe and a solid one-piece water-cooled design that promises low vibration and high heat dissipation. Both coolers incorporate quality materials that contribute to their effectiveness, but the Peerless Assassin's use of copper may provide superior thermal performance over time.
Fan Noise Levels
Noise levels are an important consideration for users seeking a quiet computing experience. Both the Thermalright Peerless Assassin and the Aqua Elite maintain a rated noise level of 25.6 dB(A), which is quite low for high-performance coolers. This means that users can expect similarly quiet operation from both models, making either choice suitable for those who prioritize silence in their builds. Whether gaming or working on demanding tasks, both coolers aim to deliver efficient cooling without excessive noise, thereby enhancing the user experience.
Aesthetics and RGB Lighting
In the realm of aesthetics, both the Thermalright Peerless Assassin 120 SE and the Aqua Elite 120 V3 feature appealing ARGB lighting effects. The Peerless Assassin boasts two high-performance ARGB fans that provide colorful lighting, which can enhance the overall look of a gaming setup. The Aqua Elite also incorporates ARGB lighting, with the fan and cooling header synchronising with the motherboard for a cohesive lighting experience. Users who appreciate visual flair will find both products attractive, but the Peerless Assassin's dual-fan setup may offer more dynamic lighting options.
Compatibility
Compatibility is a crucial factor when selecting a CPU cooler. The Thermalright Peerless Assassin supports a wide range of Intel sockets, including LGA 1150, 1151, 1155, 1156, 1200, 1700, and 1851, as well as AMD's AM4 and AM5 sockets. However, users need to use the original built-in backplate for installation on AM4 and AM5 boards. The Aqua Elite also offers broad compatibility, supporting AMD's AM4 and AM5, and Intel's LGA 1150, 1151, 1155, 1156, 1200, 2011, 2066, and 1700 sockets. This extensive compatibility ensures that both coolers can fit a variety of builds, making them versatile options for most users.
Installation Process
When it comes to installation, both coolers are designed to be user-friendly. The Thermalright Peerless Assassin features an SS2 installation system that simplifies the process, allowing for an easier setup. It comes with all necessary components but requires the original motherboard backplate for certain AMD installs. The Aqua Elite takes convenience a step further by having its fan pre-installed on the cold row, which can save time during installation. It also includes a fan hub to manage cables neatly, contributing to an aesthetically pleasing build. While both coolers are straightforward to install, users may find the Aqua Elite slightly easier due to its pre-installed components.
Which should you buy?
Deciding between the Thermalright Peerless Assassin 120 SE and the Aqua Elite 120 V3 ultimately depends on your specific needs and preferences. If budget is your primary concern, the Aqua Elite at C$41.75 is the more economical choice and still delivers excellent cooling performance. However, if you are looking for potentially superior thermal efficiency and a more robust cooling solution, the Peerless Assassin at C$48.90 may be worth the extra investment, especially for users with high-performance CPUs. Both coolers offer similar noise levels and aesthetic appeal with ARGB lighting, making either a strong contender for enhancing your cooling setup. Consider your budget, performance needs, and installation preference to make the best choice for your system.
