Overview of the Thermalright Assassin King 120 SE and Thermaltake Gravity i3

The Thermalright Assassin King 120 SE is a robust air cooler priced at $19.82, while the Thermaltake Gravity i3 is a more compact solution available for $17.79, making it about 11% cheaper. Both coolers aim to deliver effective thermal management, but they cater to different needs and preferences, particularly in terms of size, cooling performance, and compatibility.

Design and Build Quality

The Thermalright Assassin King 120 SE features a traditional tower cooler design with dimensions of 120mm x 73mm x 148mm, making it suitable for medium-sized cases. Its aluminum heat sink and S-FDB bearing fan contribute to a high-quality build. In contrast, the Thermaltake Gravity i3 adopts a low-profile design, measuring just 65.4mm in height. This makes it particularly appealing for compact builds where space is at a premium, while still providing solid cooling performance.

Cooling Performance

In terms of cooling capability, the Thermalright Assassin King 120 SE stands out with an airflow of 66.17 CFM and a maximum fan speed of 1550 RPM, ensuring efficient heat dissipation. The fan operates at a noise level of 25.6 dB(A), which is relatively quiet. On the other hand, the Thermaltake Gravity i3 offers a maximum airflow of 56.84 CFM with a fan speed ranging from 1200 to 3500 RPM, but it operates at a noise level of 36.5 dB(A), which is noticeably louder. This difference in fan performance may influence your decision based on whether you prioritize cooling efficiency or quieter operation.

Compatibility

The Thermalright Assassin King 120 SE supports a broader range of CPU sockets including Intel LGA 115X, 1200, 1700, and AMD AM4, making it versatile for various builds. In contrast, the Thermaltake Gravity i3 is specifically designed for Intel LGA 1851 and 1700 sockets, which may limit its usability if you're considering an AMD setup. This compatibility factor is crucial for builders who want to ensure their cooler will fit their specific processor.

Installation Process

Both coolers are designed for straightforward installation. The Thermalright Assassin King 120 SE comes with metal fasteners for easy mounting on both Intel and AMD platforms. The Thermaltake Gravity i3 prides itself on its quick and easy installation process, which is beneficial for users who may want to set up their systems quickly. However, the versatility of the Assassin King 120 SE in supporting multiple platforms may make it a more favorable option for users with varied setups.

Aesthetic Appeal

Aesthetic considerations play a role in many builders' choices. The Thermalright Assassin King 120 SE features colorful ARGB lighting effects, appealing to users who want to enhance their system’s visual appeal. In contrast, the Thermaltake Gravity i3 has a more understated black finish with a simple design. Users who prioritize aesthetics may lean towards the Assassin King 120 SE, while those who prefer a minimalist look might opt for the Gravity i3.

Warranty and Lifespan

Both coolers boast impressive longevity. The Thermalright Assassin King 120 SE is designed for an industrial service life of up to 20,000 hours, benefiting from high-quality materials. The Thermaltake Gravity i3, while also durable, has a fan lifetime of about 40,000 hours, which is significantly longer, albeit with the caveat that its noise levels are higher. This aspect may affect long-term satisfaction, depending on how much noise is tolerable in your working environment.

Price Consideration

The Thermalright Assassin King 120 SE retails for $19.82, while the Thermaltake Gravity i3 is priced at $17.79, making it about 11% cheaper. This price difference may be a deciding factor for budget-conscious buyers, especially considering that both products offer solid performance within their own categories. If cost is your primary concern, the Thermaltake Gravity i3 offers a compelling option, whereas the Thermalright Assassin King 120 SE provides additional features and versatility for a slightly higher price.

Which should you buy?

Ultimately, the decision between the Thermalright Assassin King 120 SE and the Thermaltake Gravity i3 hinges on your specific needs. If you're looking for a cooler with superior airflow, broad compatibility, and aesthetic features like ARGB lighting, the Thermalright Assassin King 120 SE is the better option. However, if you need a compact, budget-friendly solution primarily for Intel processors with a straightforward installation process, the Thermaltake Gravity i3 is a solid choice. Consider your system requirements and personal preferences to determine which cooler aligns best with your build.
