Price Comparison
When it comes to pricing, the MoKo 400x300mm DIY PC Case Dust Mesh Filter is significantly cheaper at £12.99 compared to the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler, which retails for £28.79. This means that the cooler comes at a price point more than double that of the dust filter. While the MoKo product serves a functional purpose of dust prevention for your PC, the Thermalright cooler is designed to enhance the performance of your CPU. Therefore, if budget is a primary concern, the MoKo filter offers a more economical choice.
Purpose and Functionality
The MoKo dust mesh filter is designed to provide a protective barrier against dust and debris, ensuring that your computer components remain clean and functional. Its 1mm holes allow for ventilation while effectively preventing the ingress of dust. On the other hand, the Thermalright CPU cooler is engineered for optimal thermal performance. It utilises advanced technologies, including six heat pipes and a dual tower design, to efficiently dissipate heat from the CPU. If your main priority is improving CPU performance, the Thermalright cooler is the better option, while the MoKo filter is ideal for maintaining a dust-free environment.
Material and Build Quality
The MoKo dust mesh filter is made from PVC material, which ensures durability while remaining lightweight for easy installation. It comes with eight magnetic strips, allowing for a hassle-free attachment process. Conversely, the Thermalright cooler features an aluminium heat sink and pure copper components, enhancing its overall thermal conductivity and effectiveness. This difference in materials reflects their intended uses; the MoKo filter is straightforward and practical, while the Thermalright cooler is built for high performance and longevity in cooling capabilities.
Installation Process
Installation of the MoKo dust mesh filter is user-friendly, thanks to its magnetic strips that do not require any drilling. You simply measure, cut, and attach it to your PC case, making it an accessible option for users who may not be tech-savvy. In contrast, the Thermalright CPU cooler requires a bit more effort during installation, as it supports multiple CPU socket types (Intel and AMD) and comes with various mounting plates and fasteners. While both products aim to enhance your computer setup, the MoKo filter is more convenient for quick installation, whereas the Thermalright cooler may require more technical skill.
Cooling and Airflow
The Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler excels in cooling performance with a maximum airflow of 66.17 CFM and a noise level of ≤25.6 dB(A) during operation. This ensures that it effectively manages CPU temperatures even under high loads. In contrast, the MoKo filter does not directly cool components but rather facilitates airflow while preventing dust accumulation. The filter’s design, featuring 1mm holes, helps maintain adequate ventilation without significantly restricting airflow. Thus, if cooling performance is your priority, the Thermalright cooler is the superior choice.
Aesthetics and Design
The Thermalright cooler not only focuses on performance but also incorporates aesthetic features with its ARGB lighting. This allows users to customise the look of their build, adding a visual appeal that many gamers and PC builders appreciate. Meanwhile, the MoKo dust mesh filter is functional without any additional aesthetic elements, focusing purely on practicality. If a visually striking setup is important to you, the Thermalright cooler offers a better design that enhances the overall look of your computer.
Brand Reputation
Thermalright boasts over 20 years of experience in the development of computer accessories, earning a solid reputation in both domestic and international markets. This pedigree gives consumers confidence in the performance and reliability of their products. MoKo, while reputable, is primarily known for its practical solutions, including the dust mesh filter. For users prioritising brand history and trust in performance, Thermalright’s established presence in the cooling market may sway their decision.
Which should you buy?
Choosing between the MoKo 400x300mm DIY PC Case Dust Mesh Filter and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific needs. If you are looking for an affordable solution to keep your computer free from dust, the MoKo filter at £12.99 is an excellent choice. However, if your goal is to enhance CPU performance and aesthetics, the Thermalright cooler, priced at £28.79, offers superior cooling capabilities and ARGB lighting. Assess your priorities—cleanliness and budget versus performance and style—to make the best decision for your setup.
