Overview of the Products
The Thermalright Assassin X 120 SE ARGB CPU Air Cooler is priced at C$24.29, while the Thermaltake Gravity i3 Intel LGA 1700 Cocket is more budget-friendly at C$20.90. Both products cater to users seeking efficient CPU cooling solutions, but they differ significantly in design and performance features.
Thermalright has established a notable reputation over its 20 years in the market, focusing on a variety of computer accessories. In contrast, Thermaltake offers a more compact solution with its Gravity i3, specifically designed for Intel's LGA 1700 socket. This comparison will delve into their respective features, design, performance, and value for money.
Design and Build Quality
The Thermalright Assassin X 120 SE features a more robust build, measuring 125mm in length, 71mm in width, and 148mm in height, with a weight of 0.645kg. This design incorporates advanced materials and a larger heat sink, which is crucial for efficient thermal management. It is equipped with metal fasteners compatible with both Intel and AMD platforms.
On the other hand, the Thermaltake Gravity i3 has a low-profile design with a height of just 2.58 inches, making it an excellent choice for compact builds. This design may limit its cooling capacity compared to the more extensive Thermalright cooler, but it enhances compatibility with smaller cases. Each product thus appeals to different user needs based on case size and cooling requirement.
Cooling Performance
In terms of cooling performance, the Thermalright Assassin X 120 SE boasts a maximum airflow of 66.17 CFM and a noise level of ≤25.6 dB(A), which means it can effectively cool high-performance CPUs while maintaining a quiet operation. Its 4×6mm heat pipes utilize AGHP technology, allowing it to handle TDPs ranging from 125W to 225W.
Conversely, the Thermaltake Gravity i3 provides an airflow of 31.343 CFM, which is significantly lower than its competitor. Its 7-bladed low-noise fan operates at a noise level of 21.3 decibels, making it a good choice for quiet environments. While it is effective for lower TDP CPUs, it may struggle with higher-performance components, limiting its appeal to users with demanding cooling needs.
Installation Process
The installation process is straightforward for both products, though they cater to different user preferences. The Thermalright Assassin X 120 SE comes with mounting hardware for both Intel and AMD processors, ensuring broad compatibility. Its installation is designed for users who may be familiar with CPU coolers, although the larger size may require more space.
The Thermaltake Gravity i3 promotes quick and easy installation, making it ideal for beginners or those looking for a hassle-free setup. Its compatibility is specifically geared towards the Intel 1700 socket, which simplifies the process for users with compatible CPUs. This ease of installation can be a strong selling point for those who prefer convenience over extensive customization.
Noise Levels
Noise levels are an important consideration when selecting a CPU cooler, and both products perform well in this regard. The Thermalright Assassin X 120 SE operates at a maximum noise level of ≤25.6 dB(A), which is relatively quiet and suitable for most environments. The use of S-FDB bearings contributes to its long service life and quiet operation, appealing to users who prioritize a silent computing experience.
In comparison, the Thermaltake Gravity i3 features a noise level of 21.3 decibels, making it slightly quieter than its competitor. This marginal difference may appeal to users who are particularly sensitive to noise. However, it is essential to note that the lower airflow of the Gravity i3 could result in less effective cooling, especially under load, which might lead to increased fan speed and noise over time.
Warranty and Reliability
Reliability is an essential consideration for CPU coolers, and both products offer different warranty periods. The Thermalright Assassin X 120 SE does not specify a warranty, which may leave potential buyers uncertain about long-term support. However, its robust build and materials suggest a strong reliability profile.
On the other hand, the Thermaltake Gravity i3 comes with a 2-year warranty, providing peace of mind for consumers. This warranty indicates the manufacturer's confidence in the product's durability and performance. For users who value warranty coverage, this could be a deciding factor in choosing the Gravity i3 over the Assassin X 120 SE.
Price Comparison
Price is always a crucial factor in any product decision, and the Thermalright Assassin X 120 SE is priced at C$24.29, while the Thermaltake Gravity i3 is slightly cheaper at C$20.90. The difference of C$3.39 may not seem substantial, but it reflects the varying features and capabilities of each cooler.
The higher price of the Thermalright product can be justified by its superior cooling performance, larger airflow, and advanced technology, making it suitable for high-performance builds. In contrast, the more affordable Thermaltake Gravity i3 offers essential cooling functionality for budget-conscious users or those with lower thermal requirements.
Which should you buy?
When choosing between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermaltake Gravity i3 Intel LGA 1700 Cocket, your choice should be guided by your specific needs. If you require superior cooling performance and are willing to spend a bit more, the Thermalright Assassin X 120 SE is the better option with its robust specifications and compatibility with high-TDP CPUs.
However, if you are looking for a cost-effective solution for a compact build and primarily use lower-powered CPUs, the Thermaltake Gravity i3 offers excellent value with its quiet operation and ease of installation. Ultimately, your decision should hinge on your cooling requirements, case size, and budget considerations.
