Price Comparison
When comparing the prices of the Thermalright Peerless Assassin 140 Black CPU Cooler and the Thermalright Aqua Elite 120 V3 Liquid CPU Cooler, the Aqua Elite is notably more affordable at C$41.75, whereas the Peerless Assassin is priced at C$54.90. This reflects a price difference of C$13.15, making the Aqua Elite a more budget-friendly option for those looking to enhance their CPU cooling without breaking the bank. The price point may be a crucial factor for budget-conscious consumers who desire effective cooling solutions.
Cooling Performance
In terms of cooling performance, the Thermalright Peerless Assassin features a dual-tower design with dual high-performance fans that can reach up to 1500 RPM and deliver an airflow of 66.17 CFM. This design promotes superior heat dissipation through its twin-tower body and six pure copper heat pipes. Conversely, the Aqua Elite employs a liquid cooling system that also boasts a 120mm ARGB fan, achieving similar fan speeds and airflow but with the additional benefits of liquid cooling efficiency. The Peerless Assassin's robust air cooling design may appeal to those preferring conventional methods, while the liquid cooling of the Aqua Elite could provide quieter operation and better sustained performance under load.
Installation Process
The installation process for both coolers is designed to be straightforward, but they differ significantly in approach. The Peerless Assassin comes with all-metal fasteners and a variety of mounting kits to ensure compatibility across multiple CPU sockets, making installation relatively easy with proper instructions. In contrast, the Aqua Elite includes a fan hub to simplify cable management and comes pre-installed with the fan on the cold row. This means users can avoid manual installation of the fan, potentially reducing setup time. Both coolers support a wide range of AMD and Intel socket types, adding flexibility for users with different CPU setups.
Noise Levels
Noise levels are a critical consideration for many PC builders, and both coolers perform admirably in this regard. The Thermalright Peerless Assassin operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for a dual-fan air cooler. The Aqua Elite matches this performance, with its dual fans also rated at a maximum noise level of 25.6 dBA. This parity in noise levels means that consumers can expect quiet operation from both cooling solutions, making either a suitable choice for a silent build.
Build Quality
Both the Thermalright Peerless Assassin and the Aqua Elite exhibit impressive build quality, but they utilize different materials and designs. The Peerless Assassin features a twin-tower aluminum body with pure copper heat pipes, promoting excellent heat dissipation and durability. On the other hand, the Aqua Elite incorporates a black aluminium fin heat sink along with a protective mesh water pipe, enhancing its longevity and reliability as a liquid cooling solution. While the Peerless Assassin focuses on a classic air cooling design, the Aqua Elite leverages modern liquid cooling technology to offer a different approach to CPU thermal management.
Aesthetics and RGB Features
Aesthetic appeal is increasingly important to many PC builders, and both coolers offer distinct visual enhancements. The Aqua Elite features ARGB lighting that synchronizes with the motherboard for a vibrant lighting effect, providing not only cooling but an impressive visual display. In contrast, the Peerless Assassin does not mention RGB features, focusing instead on its efficient cooling capabilities. Users prioritizing aesthetics may prefer the Aqua Elite for its customizable lighting options, while those who favour a more traditional look might lean towards the Peerless Assassin.
Compatibility
Compatibility is an essential aspect when selecting a CPU cooler, and both products are designed to accommodate a wide range of CPU sockets. The Thermalright Peerless Assassin supports Intel sockets, including LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA1700, and LGA1851, as well as AMD’s AM4 and AM5. Similarly, the Aqua Elite is compatible with a variety of Intel and AMD sockets, including LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA2011, LGA2066, and LGA1700, along with AM4 and AM5. This broad compatibility ensures that users of both products can find suitable mounting solutions for their systems.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 140 Black CPU Cooler and the Thermalright Aqua Elite 120 V3 Liquid CPU Cooler ultimately depends on individual priorities and preferences. If you are looking for a more budget-friendly option with solid performance and straightforward installation, the Aqua Elite at C$41.75 stands out. However, for those who prefer a robust air cooling solution with excellent heat dissipation capabilities, the Peerless Assassin at C$54.90 is a strong contender. Each cooler has its unique advantages, so your decision should hinge on whether you prioritise cost, cooling method, aesthetics, or specific installation needs.
