Overview of the Products
The GeeekPi Low-Profile Plus CPU Cooler for Raspberry Pi 5 is priced at $19.99, while the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler comes in at $32.90. This makes the Peerless Assassin about 64% more expensive than the GeeekPi cooler. Both products serve different platforms, with the GeeekPi specifically designed for the Raspberry Pi 5 and the Thermalrlght suitable for a wider range of CPUs, including Intel and AMD systems.
Design and Build Quality
The GeeekPi cooler features a low-profile design tailored for compact systems, making it ideal for the Raspberry Pi 5. Its aluminum heatsink and four-copper-pipe design enable effective heat dissipation within tight spaces. In contrast, the Thermalrlght cooler boasts a dual-tower configuration and six heat pipes with AGHP technology, which improves thermal performance and compatibility with various components. While the GeeekPi cooler is designed for aesthetic appeal in small setups, the Thermalrlght offers a more robust structure aimed at high-performance builds.
Cooling Performance
In terms of cooling efficiency, the GeeekPi cooler is designed with a direct heat exhaust fan that activates when the CPU temperature reaches 60 degrees Celsius. This feature is essential for maintaining optimal operating temperatures in compact environments. On the other hand, the Thermalrlght Peerless Assassin is equipped with dual 120mm TL-C12C PWM fans, producing impressive airflow of 66.17 CFM and maintaining low noise levels below 25.6 dB. This cooler is better suited for intensive computing tasks, providing superior cooling for high-performance CPUs.
Compatibility
The compatibility of these coolers varies significantly. The GeeekPi cooler is specifically designed to work with the Raspberry Pi 5, ensuring seamless integration with its processor. Meanwhile, the Thermalrlght Peerless Assassin supports a broader range of CPU sockets, including Intel LGA 1700 and AMD AM4/AM5, making it a versatile choice for various builds. However, for installation on AM4 and AM5 motherboards, users must use the original motherboard's built-in backplate, which is not included.
Noise Levels
When it comes to noise levels, the GeeekPi cooler operates silently until the CPU temperature threshold is reached, at which point it activates the fan. The inherent design of the cooler allows for a quieter operation, beneficial for those seeking a silent computing experience. In contrast, the Thermalrlght cooler operates at a maximum noise level of 25.6 dB while delivering high airflow. While this is still relatively quiet, users looking for ultra-silent cooling may prefer the GeeekPi's approach.
Ease of Installation
Installation ease is another crucial factor to consider. The GeeekPi cooler is straightforward to install on the Raspberry Pi 5, designed for user-friendliness in compact setups. On the flip side, the Thermalrlght Peerless Assassin comes with a more complex installation system, including a metal pressure plate and SS2 install system that enhances contact with the CPU. While it may require more effort to install due to its design and compatibility considerations, the Thermalrlght's setup ultimately leads to better performance in larger builds.
Price Comparison
The price difference between the two coolers is noteworthy; the GeeekPi cooler is priced at $19.99, making it a budget-friendly option, while the Thermalrlght cooler is more premium at $32.90. This represents a difference of about $12.91. For users primarily working with a Raspberry Pi 5, the GeeekPi cooler offers excellent value without compromising on essential cooling features. Conversely, those with more demanding computing needs may justify the higher price of the Thermalrlght cooler for its superior performance and compatibility.
Which should you buy?
Choosing between the GeeekPi Low-Profile Plus CPU Cooler and the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler ultimately depends on your specific needs. If you are looking for an affordable, efficient cooling solution for the Raspberry Pi 5, the GeeekPi cooler is an excellent choice at $19.99. However, if you require a more versatile cooler capable of handling high-performance CPUs in a variety of builds, the Thermalrlght cooler, despite its higher price of $32.90, may be the better investment. Ultimately, your decision should hinge on your system requirements and budget constraints.
