Overview of the Products

The be quiet! Pure Rock Pro 3 Black CPU Air Cooler is a high-performance cooler designed for demanding workstations and gaming setups, while the Thermaltake Gravity i2 is a budget-friendly option optimized for low power processors. With a price difference of about $42.12, the Pure Rock Pro 3 retails for $54.90, whereas the Gravity i2 is priced at only $12.78. This significant price gap reflects the different target audiences and performance capabilities of these two coolers.

Cooling Performance

The Pure Rock Pro 3 is engineered with 6 high-performance 6mm heat pipes and a 120mm PWM fan, delivering exceptional cooling power even under overclocked conditions. Its design ensures that it maintains peak performance for high-demand applications. In contrast, the Gravity i2 uses a 92mm fan with a cooling airflow of 31.343 CFM, which is adequate for low power CPUs. While both coolers aim to keep temperatures down, the Pure Rock Pro 3 is built for more intensive tasks, making it the superior choice for performance-oriented users.

Noise Levels

When it comes to noise, the Gravity i2 operates at a noise level of 21.3 decibels, making it a reasonably quiet option for desktop setups. The Pure Rock Pro 3, while not specified in its noise level, is designed for quiet operation, thanks to its optimized fan blade geometry. Users can expect a quieter performance from both coolers, though the Gravity i2’s lower price point comes with trade-offs in overall cooling capabilities.

Design and Aesthetics

The be quiet! Pure Rock Pro 3 boasts a striking design that combines power with elegance, featuring a compact offset design that enhances compatibility with RAM and VRM coolers. The aesthetic appeal of the Pure Rock Pro 3 is likely to attract users who value both performance and visual impact in their build. On the other hand, the Gravity i2 has a more utilitarian appearance, focusing primarily on function over form, which may not appeal to users looking for a visually striking cooler.

Installation Process

Ease of installation is a standout feature of the Pure Rock Pro 3, which comes with a self-explanatory mounting kit that simplifies the setup process. Its design allows for an offset mounting that is particularly beneficial for users with AMD AM5 CPUs, ensuring the base plate is centered above CPU hotspots. The Gravity i2 also promotes quick and easy installation, but its simpler design may not require as much attention to detail. For users who prioritize straightforward installation, both coolers offer user-friendly experiences, though the Pure Rock Pro 3 may be slightly more advantageous for complex builds.

Compatibility

The Pure Rock Pro 3 supports a wide range of sockets, including AMD AM4 and AM5, as well as Intel LGA 1700, 1150, 1151, and 1200. This broad compatibility makes it a versatile option for various builds. In comparison, the Gravity i2 is limited to Intel LGA 1200, 1156, 1155, 1150, and 1151, making it less flexible for users who might consider switching platforms in the future. Those looking for a cooler that can adapt to different CPUs may find the Pure Rock Pro 3 to be the better investment in the long run.

Warranty and Support

The Gravity i2 comes with a 2-year warranty, offering peace of mind for users who may experience issues with their cooler. However, the warranty information for the Pure Rock Pro 3 is not specified, which could be a drawback for potential buyers seeking longer-term support. Warranty terms can often influence purchasing decisions, and users may want to consider the level of protection each product offers before making a choice.

Which should you buy?

Choosing between the be quiet! Pure Rock Pro 3 and the Thermaltake Gravity i2 ultimately comes down to your specific needs and budget. If you are looking for high performance, superior cooling capabilities, and broad compatibility, the Pure Rock Pro 3 is worth the investment at $54.90. However, if you are on a tighter budget and need a cooler for low power CPUs, the Gravity i2 offers a cost-effective solution at $12.78. Each product has its strengths, so consider your priorities when making a decision.
