Overview of the Thermalright Peerless Assassin 140 Black CPU Cooler
The Thermalright Peerless Assassin 140 Black CPU Cooler stands out for its high-performance cooling capabilities and versatility. Priced at C$54.90, this cooler features a twin-tower design with symmetrical fins and six pure copper heat pipes, which are engineered to provide enhanced heat dissipation. Its dual 1500 RPM fans can generate an impressive airflow of 66.17 CFM while maintaining a noise level of just 25.6 dB(A), making it an excellent choice for users who value both performance and quiet operation.
This cooler’s height of 158mm makes it compatible with a range of cases, particularly large and medium-sized chassis, while its all-metal fasteners and SS2 buckle system facilitate easy installation. With broad compatibility across various Intel and AMD platforms, the Peerless Assassin is designed to meet the needs of many users looking to improve their CPU cooling.
Overview of the Thermalright Phantom Spirit 120 CPU Cooler
The Thermalright Phantom Spirit 120 CPU Cooler is priced slightly lower at C$47.90, making it a more budget-friendly option. This cooler incorporates the AGHP technology, which features a 7x6mm heat pipe designed to manage heat effectively in both vertical and horizontal orientations. The Phantom Spirit boasts a height of 157mm, allowing it to fit comfortably in a wide variety of chassis, similar to its counterpart.
This model uses a combination of anodized black frosted aluminum and a finely crafted pure copper base, enhancing its thermal conductivity. Additionally, the S-FDB bearings ensure a long service life, rated at up to 20,000 hours. The Phantom Spirit also includes a Y-type adapter for easy fan connection, highlighting its user-friendly design.
Cooling Performance Comparison
In terms of cooling performance, the Thermalright Peerless Assassin 140 Black leads with its dual 1500 RPM fans and a maximum airflow of 66.17 CFM. This significant airflow capacity is crucial for maintaining optimal CPU temperatures during high-demand tasks. The presence of six heat pipes further enhances its heat dissipation capabilities, making it a powerful contender in the CPU cooler market.
Conversely, the Thermalright Phantom Spirit 120, while effective, has a different cooling approach with its single fan design. Although the specific airflow of the Phantom Spirit is not provided, its design focuses on efficient heat transfer through the AGHP technology. The combination of its aluminum heatsink and copper base allows it to perform adequately, but it may lag behind the Peerless Assassin in high-performance scenarios where maximum cooling is essential.
Noise Levels and Acoustic Performance
When considering noise levels, the Thermalright Peerless Assassin 140 Black operates at a noise value of 25.6 dB(A), making it relatively quiet, even under load. This low noise output is a significant advantage for users seeking a cooler that doesn't disrupt their working environment or gaming experience.
On the other hand, the Thermalright Phantom Spirit 120 does not specify its noise levels, but given its focus on efficient design, it can be expected to operate quietly as well. However, without concrete figures, it’s difficult to make a direct comparison. Users prioritizing a quieter setup may lean towards the Peerless Assassin, knowing it has been explicitly rated for low noise, which can be a decisive factor for many.
Physical Dimensions and Compatibility
The Thermalright Peerless Assassin 140 Black measures 140mm in length, 157mm in width, and 158mm in height, making it a robust option for larger cases. Its compatibility spans across various Intel and AMD platforms, including LGA1700 and AM4 sockets, ensuring that it can cater to a wide range of builds.
The Thermalright Phantom Spirit 120 is slightly smaller, with dimensions of 125mm in length, 135mm in width, and 157mm in height. While it also offers compatibility with Intel and AMD sockets, its lesser size may appeal to users with space constraints. Both coolers are designed to fit most modern cases, but the choice may ultimately depend on specific build requirements and space availability.
Installation Process
Installation is made straightforward with both coolers, but the Thermalright Peerless Assassin 140 Black boasts a more comprehensive mounting system with its all-metal fasteners and SS2 buckle system. This design allows for easier and more secure installation across various CPU socket types, which can be an essential factor for DIY builders.
The Thermalright Phantom Spirit 120 is also user-friendly, featuring a Y-type fan connector to simplify the setup process. However, it may not offer the same level of versatility as the Peerless Assassin in terms of compatibility and ease of installation, particularly for users unfamiliar with CPU cooler setups.
Price Comparison and Value for Money
The Thermalright Peerless Assassin 140 Black is priced at C$54.90, while the Thermalright Phantom Spirit 120 comes in at C$47.90. The price difference of C$7.00 reflects the additional features and performance capabilities of the Peerless Assassin. For users focused on maximum cooling performance and versatility, the higher price may justify the investment.
In contrast, the Phantom Spirit offers a more economical choice without compromising on essential features. It caters to budget-conscious consumers who still desire an effective cooling solution. The decision between the two will largely depend on individual priorities regarding performance versus budget.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 140 Black and the Thermalright Phantom Spirit 120 ultimately depends on your specific needs and preferences. If superior cooling performance, quieter operation, and broader compatibility are your primary concerns, the Peerless Assassin is the clear choice. Its advanced design and features make it a strong contender for high-performance builds.
However, if you are looking for a more budget-friendly option that still delivers solid performance and a user-friendly installation process, the Phantom Spirit is an excellent alternative. It successfully balances price and functionality, catering well to average users and those with limited budgets. Thus, your choice should align with your cooling demands and financial considerations.
