Price Comparison
The Thermalright Peerless Assassin 120 SE CPU Cooler is priced at $49.99, while the Thermaltake Gravity i2 is significantly cheaper at $12.78, making it about 74% less expensive. This drastic price difference reflects the varying target markets of these coolers. The Peerless Assassin is designed for more demanding cooling requirements, suitable for higher-end CPUs, while the Gravity i2 focuses on low-power processors. If budget is your primary concern, the Gravity i2 offers a compelling option, especially for users with less intensive cooling needs.
Cooling Performance
The Thermalright Peerless Assassin 120 SE boasts enhanced cooling capabilities thanks to its dual 120mm PWM fans that reach a speed of 1550 RPM and provide an air flow of 66.17 CFM. This makes it well-suited for users who require efficient cooling for high-performance CPUs. In contrast, the Thermaltake Gravity i2 features a 92mm fan that delivers an air flow of 31.343 CFM, which is adequate for low power CPUs but may not suffice for more demanding tasks. Therefore, if peak cooling performance is your goal, the Peerless Assassin stands out as the better choice.
Noise Level
In terms of noise levels, the Thermalright Peerless Assassin operates at a maximum noise level of 25.6 dB(A), which is relatively quiet given its powerful cooling capabilities. On the other hand, the Thermaltake Gravity i2 is slightly quieter with a noise level of 21.3 decibels. If noise is a critical factor for you, especially in a compact or sound-sensitive environment, the Gravity i2 may be the more appealing option. However, the cooling performance of the Peerless Assassin justifies its slightly higher noise output.
Design and Size
The Thermalright Peerless Assassin has a larger footprint, measuring 125(L)x135(W)x155(H) mm, which may limit its compatibility with smaller cases. Conversely, the Thermaltake Gravity i2 features a low-profile design, making it more versatile for compact builds. Its smaller size allows for easier installation and better clearance for components around the CPU socket. If you’re working with a tight space or a smaller PC case, the Gravity i2's design will likely be more accommodating.
Installation
Both coolers are designed for easy installation, but they cater to different user needs. The Thermalright Peerless Assassin comes with metal fasteners compatible with various Intel and AMD platforms, ensuring a secure fit. However, it requires the use of the motherboard's built-in backplane for AMD installation. In contrast, the Thermaltake Gravity i2 promises a quick and easy installation, making it user-friendly for those who may not have extensive experience with CPU coolers. For novice builders, the Gravity i2 may present a less intimidating installation process.
Brand Reputation
Thermalright has built a solid reputation over its 20 years in the market, particularly within the gaming and performance communities. Their focus on high-quality CPU coolers is evident in the Peerless Assassin. On the other hand, Thermaltake is also well-regarded, especially for their stylish designs and user-friendly products. This brand comparison may sway customers depending on their loyalty or past experiences with either brand. Ultimately, both brands offer reliable products, but Thermalright is often preferred for performance-focused builds.
Compatibility
The Thermalright Peerless Assassin supports a broader range of CPU sockets, including Intel LGA 1700, 1150, 1151, 1200, and AMD AM4/AM5. This makes it versatile for users planning to upgrade or switch platforms in the future. In contrast, the Thermaltake Gravity i2 is optimized specifically for Intel sockets, namely LGA 1200, 1156, 1155, 1150, and 1151, which may limit its longevity for users who might switch to AMD processors. If you anticipate changing your hardware setup, the Peerless Assassin offers greater compatibility.
Which should you buy?
In conclusion, your choice between the Thermalright Peerless Assassin 120 SE and the Thermaltake Gravity i2 largely depends on your specific needs and budget. If you’re looking for superior cooling performance and compatibility with a wider range of CPUs, the Peerless Assassin is worth the investment at $49.99. However, if you need a cost-effective solution for a low-power processor and prefer a quieter, more compact option, the Gravity i2 at $12.78 stands out as an excellent choice. Ultimately, evaluate your cooling requirements, budget, and system compatibility to make the best decision for your build.
