Overview of the Thermaltake Gravity i3

The Thermaltake Gravity i3 is designed specifically for the Intel LGA 1700 socket, making it a compatible choice for newer Intel processors. Priced at C$20.90, this cooler offers a low-profile design, standing at just 2.58 inches in height, which is ideal for compact builds or cases with limited space. Its air flow rating of 31.343 CFM at a noise level of only 21.3 decibels ensures a quiet cooling experience while maintaining adequate performance.

The Gravity i3 also features a 7-bladed low noise fan that promotes efficient air circulation. Installation is made easy with a quick and straightforward process, which is beneficial for users who may not be comfortable with complex setups. Additionally, it comes with a 2-year warranty, adding a layer of assurance regarding its reliability.

Overview of the Thermalright Assassin X 120 SE

The Thermalright Assassin X 120 SE is a more robust option that supports a wider range of CPU sockets, including Intel's LGA 115X, 1200, 1700, and AMD's AM4. With a price tag of C$25.59, it brings superior performance features to the table. The cooler boasts an air flow rating of 66.17 CFM, significantly higher than the Gravity i3, which can enhance thermal performance, especially under heavier CPU loads.

Weighing in at 0.645 kg and measuring 125mm in length and 148mm in height, it fits well within medium-sized computer cases. The Assassin X is equipped with PWM fans that run at a speed of 1550 RPM, allowing for efficient cooling while maintaining a noise level of 25.6 dB(A). Its design incorporates advanced AGHP technology, which optimizes heat dissipation and makes it suitable for CPUs with a thermal design power (TDP) of up to 225W.

Cooling Performance

When comparing cooling performance, the Thermalright Assassin X 120 SE clearly takes the lead with an air flow of 66.17 CFM, more than double that of the Thermaltake Gravity i3’s 31.343 CFM. This higher air flow rating signifies the ability to move more air through the cooler, which can be crucial for maintaining lower temperatures during intense gaming sessions or heavy computational tasks.

While the Gravity i3 offers a quieter operation at 21.3 dB(A), the Assassin X operates at a slightly higher noise level of 25.6 dB(A). However, the trade-off in noise level may be worth it given the superior cooling efficiency of the Assassin X. For users seeking maximum cooling performance, particularly in overclocked setups, the Thermalright cooler's capabilities are hard to overlook.

Compatibility and Installation

In terms of compatibility, the Thermaltake Gravity i3 is limited to Intel's LGA 1700 socket, making it an excellent choice for users with compatible processors. Its ease of installation is another strong point, allowing users to set it up quickly without hassle, which is a significant advantage for novice builders.

On the other hand, the Thermalright Assassin X 120 SE offers broader compatibility, supporting both Intel and AMD sockets. This versatility makes it an appealing choice for users who may switch platforms in the future. The installation also benefits from metal fasteners, ensuring a secure fit across different CPU types. This adaptability, combined with its more complex cooling technology, makes the Assassin X a more future-proof investment.

Design and Aesthetics

Both coolers feature practical designs suited for their intended purposes, but they do differ in aesthetics. The Thermaltake Gravity i3’s low-profile design may be more appealing in compact builds, where space is a premium. Its simplicity aligns well with minimalist setups, emphasizing functionality without overwhelming the visual space.

Conversely, the Thermalright Assassin X 120 SE presents a more robust and industrial appearance, which may attract users looking for a cooler that also serves as a statement piece within their builds. Its larger size and aluminum heat sink materials contribute to a more substantial look, which can complement a range of gaming and high-performance rigs.

Noise Levels

Noise levels are an important consideration for many users, particularly those who value a quiet computing environment. The Thermaltake Gravity i3 operates at a commendably low noise level of 21.3 dB(A), making it an excellent choice for quiet builds or office environments.

The Thermalright Assassin X 120 SE, while slightly noisier at 25.6 dB(A), still falls within an acceptable range for most users. The higher air flow and cooling capacity may justify the increased noise for those who prioritize performance over silence. Ultimately, the choice between these two coolers may hinge on whether users prefer a quieter operation or enhanced cooling efficiency, especially during demanding tasks.

Price to Performance Ratio

When it comes to price, the Thermaltake Gravity i3 is the more budget-friendly option at C$20.90, making it an attractive choice for users who need basic cooling for their Intel LGA 1700 setups. However, the Thermalright Assassin X 120 SE, priced at C$25.59, offers significantly better cooling performance and versatility, justifying the slightly higher cost.

In terms of performance per dollar, the Assassin X provides more value for users who require better cooling solutions, particularly in gaming or high-performance applications. The additional investment is likely to pay off in extended component longevity and improved thermal management, making it a compelling option for serious gamers and PC builders.

Which should you buy?

Choosing between the Thermaltake Gravity i3 and the Thermalright Assassin X 120 SE ultimately depends on your specific needs and preferences. If you require an affordable, compact cooler with quiet operation for an Intel LGA 1700 setup, the Thermaltake Gravity i3 is an excellent choice. However, for users seeking superior cooling performance and versatility across multiple CPU platforms, the Thermalright Assassin X 120 SE is worth the additional investment. It stands out with its higher air flow, broader compatibility, and robust design, making it a formidable option for serious gaming and high-performance computing.
