Overview

When it comes to CPU coolers, the Thermalright Peerless Assassin 120 Black and the Thermaltake Gravity i3 cater to different needs and budgets. The Peerless Assassin is priced at $38.90, while the Gravity i3 is significantly cheaper at $17.79, making it about 54% less expensive. This price difference reflects the distinct features and cooling capabilities of each model, making them suitable for various types of users.

Design and Build Quality

The Thermalright Peerless Assassin boasts a robust design with a twin-tower configuration and six heat pipes, enhancing its cooling efficiency. It measures 125mm x 135mm x 157mm, making it a substantial cooler that not only looks impressive but also demonstrates high-performance capabilities. In contrast, the Thermaltake Gravity i3 has a low-profile design at just 2.58 inches tall, making it ideal for compact builds. Although its dimensions make it less imposing, its aluminum construction maintains decent durability. While the build quality of both coolers is solid, the Peerless Assassin's design is more complex and likely offers superior thermal performance.

Cooling Performance

The Thermalright Peerless Assassin excels in cooling performance, with a total heat dissipation area of 9600 cm² and a TDP rating of 245W. Its dual TL-C12B PWM fans, operating at a speed of 1500 RPM, provide an airflow of 66.17 CFM, ensuring efficient heat removal during high loads. On the other hand, the Thermaltake Gravity i3 is optimized for lower power processors, rated for a cooling power of 95W. Its 92mm fan can achieve a maximum airflow of 56.84 CFM, which, although effective for lower-end CPUs, falls short when compared to the Peerless Assassin's capabilities. Thus, if you require robust cooling performance, the Peerless Assassin is the clear leader.

Noise Levels

When it comes to noise levels, the Thermalright Peerless Assassin operates at a maximum noise level of 25.6 dB(A), making it relatively quiet during operation. This is impressive considering its larger size and higher airflow. In comparison, the Thermaltake Gravity i3 has a higher noise output of 36.5 dB, especially at full fan speed. Although the Gravity i3's noise level is acceptable for a budget cooler, it may become noticeable under load. Therefore, if quiet operation is a priority, the Peerless Assassin is the better choice.

Compatibility

The Thermalright Peerless Assassin supports a wide range of CPU sockets, including Intel's LGA 1150, 1151, 1155, 1156, 1200, 1700, 2066, and AMD's AM4/AM5. This extensive compatibility ensures that it can fit a variety of systems, making it a versatile option for users. Meanwhile, the Thermaltake Gravity i3 is specifically designed for Intel's LGA 1700 and 1851 sockets. While it caters well to users with these specific socket types, its limited compatibility may restrict its appeal to those with different setups.

Installation Process

Both coolers offer straightforward installation processes, but the Thermaltake Gravity i3 has an edge in this category. Its low-profile design and compact size allow for quick and easy installation, making it user-friendly for those new to building PCs. The Thermalright Peerless Assassin, while not overly complicated to install, has a more intricate setup due to its larger size and dual tower design. Thus, if ease of installation is a significant factor for you, the Gravity i3 presents a more accessible option.

Warranty and Support

The Thermaltake Gravity i3 comes with a two-year warranty, providing users with peace of mind regarding its longevity and performance. In contrast, specific warranty details for the Thermalright Peerless Assassin are not mentioned, which may leave potential buyers uncertain about long-term support. A solid warranty can significantly influence purchasing decisions, especially for budget-conscious consumers. Therefore, the Gravity i3 has a slight advantage in this regard, as it explicitly offers warranty coverage.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 Black and the Thermaltake Gravity i3 ultimately comes down to your specific needs and budget. If you require high-performance cooling with excellent thermal capabilities and are willing to invest more, the Peerless Assassin is the superior option. On the other hand, if you are looking for a budget-friendly solution for low-power processors with a simpler installation process, the Gravity i3 is an excellent choice. Each cooler serves its purpose well, ensuring users can find a suitable option based on their individual requirements.
