Overview of the Products
The Thermalright Peerless Assassin 120 SE CPU Cooler is priced at $49.99, while the Thermaltake Gravity i3 is significantly less expensive at $17.79, making it about 64% cheaper than its competitor. Both coolers cater to different user needs, with the Thermalright offering a more robust cooling solution, while the Thermaltake focuses on compactness and ease of installation for lower power processors. This comparison will delve into their features, compatibility, performance, and overall value.
Cooling Performance
The Thermalright Peerless Assassin 120 SE boasts a dual-fan design with a maximum fan speed of 1550 RPM and an airflow rate of 66.17 CFM. This configuration is engineered for high-performance cooling, making it suitable for demanding CPUs. In contrast, the Thermaltake Gravity i3 has a single 92mm fan with a maximum airflow of 56.84 CFM, which may suffice for less demanding tasks but limits its efficiency with high-performance CPUs. Users seeking superior cooling will likely prefer the Thermalright, while those with lower power requirements may find the Thermaltake adequate.
Design and Size
When it comes to design, the Thermalright Peerless Assassin 120 SE measures 125x135x155 mm, which makes it a larger cooler that could pose compatibility challenges in compact cases. The Thermaltake Gravity i3, on the other hand, stands at a height of just 65.4 mm, offering a low-profile design that is particularly advantageous for smaller builds. This difference in size is crucial for users with limited space, as the Gravity i3 can fit into tighter configurations without obstructing other components.
Noise Levels
The Thermalright Peerless Assassin 120 SE operates at a noise level of ≤25.6 dB(A), making it relatively quiet during operation. In contrast, the Thermaltake Gravity i3 has a noise level of 36.5 dBa, which is noticeably higher. Users prioritizing a quiet computing environment would likely favor the Thermalright cooler, while the Thermaltake's noise level might be acceptable in less noise-sensitive setups.
Installation Process
The installation process for both coolers differs significantly. The Thermalright Peerless Assassin 120 SE comes equipped with metal fasteners for both Intel and AMD platforms, but requires users to check their case and motherboard compatibility due to its size. The Thermaltake Gravity i3 is designed for quick and easy installation, specifically optimized for LGA 1700 and 1851 sockets. Its low-profile design further simplifies the installation process, making it a more user-friendly option for beginners or those seeking a hassle-free setup.
Compatibility
Compatibility is a crucial factor when selecting a CPU cooler. The Thermalright Peerless Assassin 120 SE supports a wide range of sockets, including Intel LGA 1700, 1150, 1151, 1152, 1200, and 1851, as well as AMD AM4 and AM5. This extensive compatibility makes it a versatile choice for users with various system configurations. The Thermaltake Gravity i3, while focused on Intel users, only supports LGA 1700 and 1851 sockets. Therefore, if you plan to upgrade your CPU in the future, the Thermalright cooler offers greater flexibility.
Brand Reputation
Thermalright has built a strong reputation over its 20 years in the market, particularly recognized within enthusiast circles for its high-performance cooling solutions. The brand has garnered a loyal following, and its products often receive favorable reviews. Thermaltake, while also respected, primarily targets budget-conscious consumers and those with simpler cooling needs. This brand reputation can influence purchasing decisions, as users may lean towards the Thermalright Peerless Assassin 120 SE for its proven track record in performance.
Price Comparison
The price difference between the Thermalright Peerless Assassin 120 SE at $49.99 and the Thermaltake Gravity i3 at $17.79 is substantial, with the latter being approximately 64% cheaper. This drastic price gap reflects the varying target audiences of the two products. The Thermalright is designed for users seeking high-end cooling performance, while the Thermaltake caters to those looking for a budget-friendly solution. Ultimately, the choice will depend on the user's specific cooling requirements and budget constraints.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE and the Thermaltake Gravity i3 ultimately depends on your cooling needs and system compatibility. If you're looking for superior cooling performance, extensive compatibility, and quieter operation, the Thermalright is the clear winner, despite its higher price tag. However, if you're on a budget and need a compact cooler for low-power Intel CPUs, the Thermaltake Gravity i3 serves as a solid choice. Consider your specific requirements and preferences to make the best decision for your setup.
