Overview of the Products
In this comparison, we will examine the ELUTENG USB PC Computer Fan 140mm and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler. The ELUTENG fan is priced at £16.99, making it a budget-friendly cooling solution, while the Thermalright cooler is more premium at £28.79. Each product serves distinct purposes within the cooling category, with the ELUTENG fan designed for versatile use across various devices, and the Thermalright cooler specifically targeting CPU cooling for gaming and high-performance PCs.
Design and Build Quality
The design of the ELUTENG USB PC Computer Fan is compact and practical, featuring a dual-fan setup that is ideal for cooling multiple devices simultaneously. Each fan has an airflow of about 56CFM and operates at a maximum speed of 1500RPM. The build quality includes a black metal grill guard for safety and durability, making it suitable for use in tight spaces. In contrast, the Thermalright Peerless Assassin 120 SE ARGB boasts a more complex build, featuring six heat pipes and dual PWM fans that provide up to 66.17CFM at similar speeds of 1500RPM. The use of pure copper in its construction enhances its thermal performance, making it a robust option for serious gamers and PC builders.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin clearly outshines the ELUTENG fan. With a maximum airflow of 66.17CFM compared to the ELUTENG's 56CFM, the Thermalright cooler is designed for high-performance CPU cooling, leveraging advanced technology such as the AGHP technique to enhance thermal efficiency. It operates quietly at a noise level of 25.6 dB, similar to the ELUTENG fan's range of 25.6 dB to 32.5 dB. This means that while both products are relatively quiet, the Thermalright cooler is engineered for superior cooling under load, making it more suitable for demanding applications.
Compatibility
The compatibility of the ELUTENG fan is broad, as it connects via USB and can be used with any device that has a USB power supply, including PCs, laptops, and gaming consoles. This flexibility makes it a versatile choice for users looking for a simple cooling solution. On the other hand, the Thermalright Peerless Assassin is specifically designed for CPU cooling and supports various socket types, including Intel's 115X, 1200, 1700, and AMD's AM4 and AM5. This targeted compatibility ensures that it can be easily integrated into most modern desktop systems, although it may not serve as a general-purpose cooling solution like the ELUTENG fan.
Noise Levels
Noise levels are a critical consideration for users concerned about a quiet computing environment. The ELUTENG fan operates within a range of 25.6 dB to 32.5 dB depending on the speed setting. This means that while it can produce more noise at higher speeds, it also allows for quieter operation when needed. In comparison, the Thermalright Peerless Assassin maintains a maximum noise level of 25.6 dB, which is impressive given its higher airflow capacity. For users prioritising a silent operation while gaming or working, the Thermalright cooler may be the more appealing option, providing both performance and quietness.
Use Cases
The intended use cases for these two products differ significantly. The ELUTENG USB fan is perfect for anyone needing additional cooling for devices such as laptops, gaming consoles, and projectors. It is especially useful in tight spaces where airflow is limited. Conversely, the Thermalright Peerless Assassin is tailored for PC builders and gamers who require effective cooling solutions for high-performance CPUs. Its advanced design and higher airflow make it ideal for systems that generate significant heat during intensive tasks like gaming or video editing.
Price Point
Pricing is also a key aspect in this comparison. The ELUTENG USB fan is priced at £16.99, making it an attractive option for those on a budget or for users needing additional cooling without a significant investment. On the other hand, the Thermalright Peerless Assassin, at £28.79, represents a higher initial cost but offers advanced cooling capabilities and is targeted toward serious gamers and PC enthusiasts. The price difference reflects the varying levels of performance and intended use for each product, making it essential for buyers to consider their specific needs.
Which should you buy?
Ultimately, the choice between the ELUTENG USB PC Computer Fan and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler depends on your specific cooling needs. If you require a versatile, budget-friendly cooling solution for various devices, the ELUTENG fan is an excellent choice. However, if you are a gamer or PC builder looking for high-performance CPU cooling with advanced features, the Thermalright cooler is worth the investment. Each product has its strengths, making it essential to evaluate your requirements before making a decision.
