Overview of the Products
The GeeekPi Low-Profile Plus CPU Cooler for Raspberry Pi 5 is priced at $19.99, while the Thermalright Peerless Assassin 120 Black CPU Air Cooler comes in at $38.90, making it approximately 17% more expensive than the GeeekPi. Both coolers cater to different user needs, one focusing on compact compatibility for Raspberry Pi, and the other offering robust cooling solutions for a variety of Intel and AMD processors.
Design and Build Quality
The GeeekPi Low-Profile Plus CPU Cooler features a sleek, compact design aimed at high-performance computing in tight spaces. Its four-copper-pipe design enhances thermal performance, making it ideal for Raspberry Pi 5 users. In contrast, the Thermalright Peerless Assassin boasts a dual-tower design with a total effective heat dissipation area of 9600 cm², suggesting a focus on extensive cooling capability. This cooler's black-painted aluminum fin construction not only improves aesthetics but also contributes to its heat dissipation performance, showcasing a higher-end build quality.
Cooling Performance
Cooling performance is a critical factor, and both coolers excel in their respective domains. The GeeekPi's integrated fan activates at 60 degrees Celsius, ensuring that the Raspberry Pi maintains optimal operating temperatures. Meanwhile, the Thermalright Peerless Assassin, equipped with two PWM fans, reaches a maximum airflow of 66.17 CFM, allowing it to cool CPUs with a thermal design power (TDP) of up to 245W. This significant difference in cooling capacity highlights the Thermalright's suitability for high-performance desktops, whereas the GeeekPi is tailored for compact systems.
Compatibility
In terms of compatibility, the GeeekPi Low-Profile Plus is specifically designed for the Raspberry Pi 5, making it a straightforward choice for users of this platform. On the other hand, the Thermalright Peerless Assassin supports a variety of CPU socket types, including Intel's LGA 1700 and 115X series, as well as AMD's AM4 and AM5. This broad compatibility makes the Thermalright a versatile option for users looking to upgrade their cooling solution across different builds.
Installation Process
The installation process for both coolers is designed with user convenience in mind. The GeeekPi's setup is simple and efficient, allowing Raspberry Pi users to easily attach the cooler without complex procedures. Conversely, the Thermalright Peerless Assassin comes with metal fasteners for both Intel and AMD platforms, ensuring a secure fit. However, the dual-tower design may require more careful handling during installation compared to the more straightforward design of the GeeekPi.
Noise Levels
Noise levels are an important consideration for many users. The GeeekPi's fan is designed to turn on only when necessary, which helps in minimizing noise during idle periods. The Thermalright Peerless Assassin, with its dual fans operating at a noise level of 25.6 dB(A), aims to provide effective cooling while maintaining a relatively quiet operation. Users who prioritize silence may find the GeeekPi's design preferable, while those seeking superior cooling performance might opt for the Thermalright, accepting slightly higher noise levels.
Price Comparison
The price difference between the two products is notable, with the GeeekPi Low-Profile Plus at $19.99 and the Thermalright Peerless Assassin at $38.90. This nearly $19 increase represents about a 95% price difference. For users on a budget or those specifically using a Raspberry Pi 5, the GeeekPi offers an appealing solution. However, for those needing advanced cooling for high-end CPUs, the investment in the Thermalright may be justified due to its superior features.
Which should you buy?
Choosing between the GeeekPi Low-Profile Plus CPU Cooler and the Thermalright Peerless Assassin 120 Black CPU Air Cooler ultimately depends on your specific needs. If you're a Raspberry Pi 5 user looking for an affordable, compact cooling solution, the GeeekPi at $19.99 offers excellent value. However, if you're an enthusiast with higher performance requirements and need compatibility with a range of Intel and AMD CPUs, the Thermalright at $38.90 provides superior cooling capabilities and versatility. Your decision should reflect your computing needs and budget constraints.
