Price Comparison

The Thermalright Peerless Assassin 120 SE V3 CPU Air Cooler is priced at $35.90, while the Thermaltake Gravity i3 is significantly cheaper at $17.79, making it about 50% less expensive. This price difference could be a crucial factor for budget-conscious consumers looking for effective cooling solutions. The Thermalright model offers advanced features and higher performance capabilities, but if cost is a primary concern, the Thermaltake model presents a highly attractive option for users with lower power requirements.

Cooling Performance

In terms of cooling performance, the Thermalright Peerless Assassin boasts a dual-tower design with dual PWM fans that can reach speeds of up to 2000 RPM, providing a maximum air volume of 70.84 CFM. This design is optimized for dissipating heat effectively, making it suitable for higher-end CPUs. On the other hand, the Thermaltake Gravity i3, with its 92mm fan, offers a maximum airflow of 56.84 CFM at a lower fan speed range of 1200 to 3500 RPM. While both coolers can handle their respective CPU power levels, the Thermalright unit is designed for more intense cooling needs, making it the better choice for high-performance setups.

Noise Levels

Noise levels are an important consideration for many PC builders. The Thermalright Peerless Assassin has an operating noise level of up to 29.8 dB(A), which is relatively quiet given its cooling capabilities. Conversely, the Thermaltake Gravity i3 operates at a higher noise level of 36.5 dB(A). Although the Gravity i3 is designed to be low noise with its 7-bladed fan, it may not be as quiet under load compared to the Thermalright. This difference could be significant for users who prioritize a silent computing environment.

Design and Build Quality

When examining design, the Thermalright Peerless Assassin features a robust double-tower structure with a full aluminum heatsink cover and six heat pipes, emphasizing durability and efficiency. Its sleek black anodized finish adds an aesthetic appeal. In contrast, the Thermaltake Gravity i3 has a compact, low-profile design, measuring just 2.58 inches in height, making it suitable for smaller cases. While both coolers are constructed from aluminum, the Thermalright’s advanced design and materials lend it a more premium feel, ideal for users seeking both style and performance.

Installation Process

Installation can significantly affect user experience. The Thermalright Peerless Assassin comes with mounting accessories for both Intel and AMD platforms, requiring the use of the original backplate for AMD installations. This could complicate the installation process slightly for some users. On the other hand, the Thermaltake Gravity i3 is touted for its quick and easy installation, specifically optimized for LGA 1700 and 1851 socket types. For those who prefer a straightforward setup, the Gravity i3 provides a user-friendly experience without the need for complex adjustments.

Compatibility

Compatibility is another critical factor in choosing a CPU cooler. The Thermalright Peerless Assassin supports a wide range of sockets, including Intel LGA 1700, 1150, 1151, and AMD AM4/AM5, ensuring versatility for different builds. The Thermaltake Gravity i3, while compatible with the Intel 1851 and 1700 sockets, has a more limited application, primarily targeting lower power processors with a cooling capacity of 95W. Users with higher-end CPUs may find the Thermalright cooler to be a more suitable option due to its broader compatibility and enhanced cooling capabilities.

Warranty

Warranty offerings can provide peace of mind for consumers. The Thermalright Peerless Assassin does not explicitly state a warranty period in the provided data, which may leave some buyers uncertain about long-term reliability. The Thermaltake Gravity i3, however, comes with a solid 2-year warranty, indicating the brand's confidence in its product's durability. For consumers who value warranty coverage, the Thermaltake option may stand out as the more secure choice.

Which should you buy?

Deciding between the Thermalright Peerless Assassin 120 SE V3 and the Thermaltake Gravity i3 ultimately depends on your specific needs. If you require high-performance cooling for a powerful CPU and are willing to invest more, the Thermalright model is an excellent choice, offering superior airflow, quieter operation, and enhanced compatibility. However, if you're looking for a budget-friendly, compact cooler for a low-power processor, the Thermaltake Gravity i3 is a compelling option at a fraction of the price. Evaluate your requirements to make the best decision for your setup.
