Overview of the Products
The Thermalright Peerless Assassin 120 SE CPU Air Cooler is designed for high-performance cooling, while the ELUTENG USB PC Computer Fan offers versatility for various electronic devices. Each product caters to different cooling needs; one is focused on CPU cooling in desktop builds, and the other serves as a supplementary fan for diverse applications.
Price Comparison
The Thermalright Peerless Assassin 120 SE is priced at £26.90, making it a premium choice for CPU cooling solutions. In contrast, the ELUTENG USB PC Computer Fan is significantly more affordable at £16.99. This price difference of £9.91 can be a deciding factor for budget-conscious consumers looking for effective cooling without the need for a dedicated CPU cooler.
Cooling Performance
The Thermalright Peerless Assassin 120 SE boasts impressive performance with dual PWM fans that can achieve an airflow of 66.17 CFM at a noise level of 25.6 dB(A). This cooler is specifically engineered for CPU cooling, utilising advanced AGHP technique with six pure copper heat pipes to ensure efficient heat dissipation. Meanwhile, the ELUTENG USB PC Computer Fan provides a maximum airflow of approximately 56 CFM at a noise level ranging from 25.6 dB to 32.5 dB, making it less powerful for CPU cooling but suitable for general use in various devices.
Design and Build Quality
The Thermalright Peerless Assassin features a robust design with dimensions of 125(L)x135(W)x155(H)mm, and it weighs 0.97kg, indicating a solid build quality ideal for effective heat management. It utilises high-quality materials, including aluminium and copper, which are essential for optimal thermal conductivity. The ELUTENG fan, measuring 14x14x2.5cm, is lightweight and designed with a black metal grill for safety, ensuring durability while maintaining a compact footprint suitable for tight spaces.
Versatility and Compatibility
The ELUTENG USB PC Computer Fan excels in versatility, as it can be connected via USB and used with various devices such as PCs, laptops, gaming consoles, and even projectors. Its three-speed adjustable control allows users to tailor the airflow according to their needs. On the other hand, the Thermalright Peerless Assassin is specifically designed for CPU cooling and supports a wide range of Intel and AMD sockets, making it compatible with various builds but limiting its application to desktop cooling.
Noise Levels
Both fans maintain a relatively low noise output, with the Thermalright Peerless Assassin operating at a maximum noise level of 25.6 dB(A), which is ideal for quiet environments. The ELUTENG fan ranges from 25.6 dB at its lowest speed to 32.5 dB at high speed, making it potentially noisier under certain conditions. This factor is crucial for users who prioritise a silent operation, particularly in home or office settings.
Installation and Setup
The Thermalright Peerless Assassin is designed for easy installation with metal fasteners compatible with multiple CPU platforms. This ease of installation is further enhanced by its double tower cooling design that leaves ample room for RAM, ensuring a hassle-free setup. In contrast, the ELUTENG fan requires a simple plug-and-play USB connection, making it convenient for users who need immediate cooling without extensive setup. However, it is less suited for those looking for a dedicated solution for CPU cooling.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE CPU Air Cooler and the ELUTENG USB PC Computer Fan depends largely on your specific cooling needs. If you require a high-performance cooling solution for a desktop CPU, the Thermalright unit provides superior airflow and compatibility with various sockets, albeit at a higher price. Alternatively, if you're seeking a versatile and budget-friendly cooling option for multiple devices, the ELUTENG fan is an excellent choice, especially for casual use. Ultimately, your decision should align with your cooling requirements, installation preferences, and budget constraints.
