Price Comparison

When it comes to price, the GeeekPi Low-Profile Plus CPU Cooler for Raspberry Pi 5 is significantly more affordable, priced at $19.99. In contrast, the Thermalright Peerless Assassin 120 SE CPU Cooler is priced at $49.99, making it about 150% more expensive than the GeeekPi cooler. For budget-conscious consumers or those who only need cooling solutions for compact systems like the Raspberry Pi 5, the GeeekPi offers a compelling option.

Design and Build Quality

The design of the GeeekPi Low-Profile Plus is tailored for compact setups, featuring a low-profile design that is crucial for systems with limited space. It incorporates a four-copper-pipe design along with aluminum fins to enhance heat dissipation. On the other hand, the Thermalright Peerless Assassin is slightly bulkier, measuring 125mm x 135mm x 155mm, and it boasts a double tower design and six heat pipes for superior cooling performance. The solid build quality of both products is apparent, but their intended applications differ significantly, with the Thermalright being better suited for high-performance PCs.

Cooling Efficiency

Cooling efficiency is where the Thermalright Peerless Assassin 120 SE shines, thanks to its six heat pipes and dual 120mm PWM fans that can reach speeds of 1550 RPM. This configuration allows it to deliver a maximum airflow of 66.17 CFM, which is crucial for keeping high-performance CPUs cool during intensive tasks. The GeeekPi Low-Profile Plus, while effective for its intended application, employs a single integrated fan and is designed to activate when CPU temperatures reach 60 degrees Celsius. For users with demanding workloads, the Thermalright cooler is likely the better choice for maintaining optimal temperatures.

Compatibility

Compatibility varies significantly between the two coolers. The GeeekPi Low-Profile Plus is specifically designed for the Raspberry Pi 5, ensuring seamless integration with this microcomputer. Conversely, the Thermalright Peerless Assassin supports a wide array of sockets, including AMD AM4 and AM5 as well as several Intel sockets, making it versatile for different PC builds. This broad compatibility allows users to upgrade their systems without needing to replace their cooler, a significant advantage for PC builders.

Noise Levels

In terms of noise levels, the Thermalright Peerless Assassin operates at a maximum noise level of 25.6 dB(A), which is fairly quiet given its powerful cooling capabilities. The GeeekPi Low-Profile Plus does not specify its noise levels, but it is designed to activate its fan only at higher temperatures, suggesting it may remain quieter during normal operations. For users looking for a silent operation during less intensive tasks, the GeeekPi may offer an edge, while the Thermalright is geared towards those who prioritize cooling performance, even if it may produce more noise under load.

Brand Reputation

Both brands have established a solid reputation in the cooling market, but they cater to different audiences. GeeekPi is primarily known for its products tailored to Raspberry Pi users, focusing on compact and efficient solutions. Thermalright, on the other hand, has been around for over 20 years and is recognized for its high-performance cooling solutions suitable for gamers and PC enthusiasts. Depending on the user's needs—whether for a compact Raspberry Pi setup or a robust gaming rig—brand preference can play a significant role in the decision-making process.

Installation Process

The installation process for each cooler varies significantly due to their design and intended platforms. The GeeekPi Low-Profile Plus is designed for easy installation on the Raspberry Pi 5, which is a straightforward process for users familiar with this microcomputer. In contrast, the Thermalright Peerless Assassin requires more careful consideration regarding compatibility with various Intel and AMD sockets, necessitating the use of specific mounting plates or fasteners. Users may find the installation of the Thermalright cooler to be more complex, especially if they are new to PC building.

Which should you buy?

Ultimately, the choice between the GeeekPi Low-Profile Plus CPU Cooler and the Thermalright Peerless Assassin 120 SE comes down to specific needs and use cases. If you are using a Raspberry Pi 5 and seek an affordable, compact solution, the GeeekPi at $19.99 is an excellent choice. However, for users looking for superior cooling performance in a high-performance PC build, the Thermalright at $49.99 provides exceptional cooling capabilities and versatility. Depending on your budget and requirements, each cooler has its advantages, making them suitable for different types of users.
