Dimension comparison
Overview of the Products
In this comparison, we’ll look at the Thermalright Peerless Assassin 120 CPU Air Cooler and the Thermaltake Gravity i3 Intel LGA 1700 Cocket. The Thermalright model is priced at C$51.39, while the Thermaltake model is significantly more affordable at C$20.90. This price difference suggests that the Thermalright cooler may offer superior performance or features, but we will explore each product's specifications and capabilities to determine their respective merits.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin 120 stands out with its impressive heat dissipation area of 9600 cm² and a thermal design power (TDP) rating of 245W. This makes it suitable for high-performance CPUs under heavy loads. In contrast, the Thermaltake Gravity i3 offers a lower air flow rate of 31.343 CFM, which is considerably less than the Thermalright cooler's capabilities. The Peerless Assassin's dual tower design and six heat pipes are engineered to provide optimal cooling efficiency, making it a better choice for gamers or content creators who push their CPUs to the limit.
Design and Compatibility
The design differences between the two coolers are notable. The Thermalright Peerless Assassin 120 features an offset asymmetric layout that allows for unrestricted installation, even in tight spaces. This design also helps leave room for memory chips, which is a crucial consideration for many builds. On the other hand, the Thermaltake Gravity i3 has a low-profile design with a height of only 2.58 inches, making it a great option for compact builds. However, the Gravity i3 is only compatible with Intel's LGA 1700 socket, limiting its versatility compared to the Thermalright cooler, which supports multiple Intel and AMD sockets.
Noise Levels
Noise levels can be a significant factor when choosing a CPU cooler. The Thermalright Peerless Assassin 120 operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for its performance capabilities. Meanwhile, the Thermaltake Gravity i3 is even quieter, with a noise level of just 21.3 dB. This lower noise output may appeal to users who prioritize a silent working environment, but it comes at the cost of cooling performance. Therefore, while the Gravity i3 is quieter, it may not provide the same level of cooling efficiency as the Peerless Assassin.
Installation Process
Installation ease is another aspect to consider. The Thermalright Peerless Assassin 120 comes with metal fasteners for both Intel and AMD platforms, ensuring a straightforward installation process. Its design accommodates various CPU socket types, providing flexibility for users. The Thermaltake Gravity i3 boasts a quick and easy installation, which is beneficial for those who prefer a hassle-free setup. However, its limited compatibility with only the Intel 1700 socket may restrict some users. Thus, while both coolers are designed for easy installation, the Peerless Assassin offers broader compatibility.
Aesthetics and RGB Features
The Thermalright Peerless Assassin 120 features vibrant ARGB lighting effects, enhancing the visual appeal of any build. The high-brightness LED atomizing fan blades not only provide aesthetic value but also create a synchronized lighting model controlled via the motherboard, making it an attractive option for gamers or users who enjoy customizable lighting. In comparison, the Thermaltake Gravity i3 does not mention any RGB features and presents a more utilitarian design focused on functionality over aesthetics. For users who value the look of their gaming rig, the Thermalright model is clearly the more appealing choice.
Warranty and Longevity
Warranty can often be a reflection of a product's reliability. The Thermalright Peerless Assassin 120 does not specify a warranty period, which may raise concerns about its long-term durability. Conversely, the Thermaltake Gravity i3 comes with a two-year warranty, providing peace of mind for buyers. This warranty suggests that Thermaltake stands behind the longevity of their product, making it a safer option for budget-conscious consumers. However, the lack of warranty specifics for the Peerless Assassin makes it difficult to gauge its long-term reliability.
Price Consideration
The price difference between the two coolers is significant, with the Thermalright Peerless Assassin 120 retailing for C$51.39 and the Thermaltake Gravity i3 at C$20.90. This nearly C$30 gap raises questions about value for money. While the Peerless Assassin offers higher performance and features, the Gravity i3 provides a cost-effective solution for users with less demanding cooling needs. For those on a budget or who require a less powerful solution, the Gravity i3 may represent better value, despite its limitations in cooling performance and compatibility.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 and the Thermaltake Gravity i3 ultimately depends on your specific needs and budget. If you require superior cooling performance, compatibility across multiple platforms, and are willing to invest more, the Thermalright Peerless Assassin 120 is the clear winner. However, if you are looking for a budget-friendly, quieter option for a compact build and primarily use Intel's LGA 1700 socket, the Thermaltake Gravity i3 may suffice. Assess your requirements carefully to make the best choice for your CPU cooling needs.
