Dimension comparison
Overview of the Products
In this comparison, we examine the Thermalright Peerless Assassin 140 Black CPU Cooler and the Laptop Cooling Fan by Yoidesu. The former is priced at C$54.90, while the latter is significantly more affordable at C$20.83. Although both products aim to enhance cooling performance, their target applications and design features differ greatly.
Design and Build Quality
The Thermalright Peerless Assassin 140 Black CPU Cooler is constructed with a twin-tower design featuring pure copper heat pipes and aluminium fins, optimizing heat dissipation. Its height of 158mm allows it to fit well in larger cases while accommodating high-profile memory and graphics cards. Conversely, the Laptop Cooling Fan is designed with portability in mind, made from durable aluminum alloy and ABS material. Its lightweight construction ensures it won't add significant burden to your laptop. While the Peerless Assassin targets high-performance cooling for desktop CPUs, the Laptop Cooling Fan is tailored for specific ASUS laptop models.
Cooling Performance
The cooling performance of the Thermalright Peerless Assassin is impressive, boasting dual PWM fans that can reach speeds of 1500 RPM. This cooler can deliver an air volume of 66.17 CFM, making it highly effective for dissipating heat generated by high-performance CPUs. On the other hand, the Laptop Cooling Fan operates at a lower capacity, utilising a 4-pin connector for power, which enables it to enhance cooling but lacks the high airflow numbers of the Thermalright product. It aims to reduce temperatures in laptops but is not designed to handle the same thermal loads as a dedicated CPU cooler.
Compatibility
Compatibility is another critical factor in this comparison. The Thermalright Peerless Assassin is versatile, supporting various CPU sockets including Intel's LGA1150 to LGA1851 and AMD's AM4/AM5. This makes it suitable for a wide range of desktop builds. In contrast, the Laptop Cooling Fan is specifically designed for certain ASUS TUF Gaming models, limiting its application to those compatible laptops. If you're looking for a cooler that can serve various desktop setups, the Peerless Assassin is the clear winner.
Installation Process
The installation of the Thermalright Peerless Assassin is supported by an all-metal fastener system, which simplifies the mounting process. It includes a Y-type adapter cable for connecting the dual fans, ensuring efficient operation. The Laptop Cooling Fan, meanwhile, is marketed as easy to install, requiring minimal effort to connect and operate. However, this simplicity does not compare to the comprehensive installation support offered by the Peerless Assassin, particularly for various desktop configurations.
Noise Levels
Noise levels are crucial for users who prefer a quieter computing environment. The Thermalright Peerless Assassin operates with a noise level of ≤25.6 dB(A), which is relatively quiet for a cooling solution of its size and power. In contrast, the Laptop Cooling Fan does not specify a noise rating, but its smaller size and lower airflow suggest it may operate quietly as well. However, without specific data, it’s hard to make a definitive comparison.
Price-to-Performance Ratio
At C$54.90, the Thermalright Peerless Assassin offers a robust cooling solution suitable for high-performance CPUs, making it a worthwhile investment for gamers and professionals who require effective cooling. The Laptop Cooling Fan, priced at C$20.83, serves as a budget-friendly option for casual users needing additional cooling for their laptops. While the lower price of the Laptop Cooling Fan makes it appealing, the Peerless Assassin’s superior cooling performance justifies its higher price point for serious users.
Target Audience
The Thermalright Peerless Assassin 140 Black CPU Cooler targets gamers, overclockers, and PC builders who demand top-tier cooling performance for their desktop systems. Its advanced features and compatibility with a wide range of CPU sockets cater to enthusiasts looking to push their hardware to the limit. On the other hand, the Laptop Cooling Fan is designed for casual users who own specific ASUS TUF Gaming laptops and wish to improve their device's thermal management without substantial investment. Each product serves a distinct audience with varying needs.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 140 Black CPU Cooler and the Laptop Cooling Fan ultimately depends on your specific requirements. If you are a gamer or a PC enthusiast seeking high performance and compatibility with various desktop CPUs, the Peerless Assassin is the better choice despite its higher price. However, if you own a compatible ASUS laptop and are looking for an economical solution to improve cooling, the Laptop Cooling Fan offers a practical and budget-friendly alternative. Consider your cooling needs and system compatibility before making a decision.
