Introduction to CPU Coolers
When it comes to cooling your CPU, the right cooler can significantly impact performance and longevity. In this article, we will compare two models from Thermalright: the Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler and the Thermalright AXP90 X47 Full Low Profile CPU Cooler. Each offers unique features and benefits, making them suitable for different builds and user preferences.
Design and Aesthetics
The Thermalright Assassin X 120R features a striking design with a digital ARGB top cover that adds a modern flair to any build. Its 151mm height is designed for compatibility with most cases, combining aesthetics with performance. In contrast, the AXP90 X47 boasts an ultra-compact design, standing at only 47mm tall. This makes it an ideal choice for smaller form factor builds, such as ITX cases, where space is a premium. While the first model focuses on style and heat dissipation, the latter prioritizes a low-profile footprint, catering specifically to compact setups.
Cooling Performance
The cooling capabilities of both products are impressive, but they cater to different needs. The Thermalright Assassin X 120R utilizes a 2000RPM PWM fan and features four heat pipes, enhancing its heat dissipation efficiency. This design ensures effective cooling even under heavy loads. The AXP90 X47, while lower in height, also includes four heat pipes and a 92mm PWM fan that operates quietly at a noise level of 22.4dB(A), making it suitable for users seeking a balance between cooling and noise. The choice between these two coolers largely depends on the thermal demands of your CPU and case configuration.
Noise Levels
Noise output is an important consideration for many PC builders. The Thermalright AXP90 X47 is designed to operate quietly, with a maximum noise level of 22.4dB(A), making it an excellent choice for those who prefer a silent computing environment. On the other hand, the Assassin X 120R, while not specifically rated for noise, utilizes silicone corner pads around the fan to minimize vibrations and noise. Its higher RPM fan may produce more sound under load, which could be a consideration for users sensitive to noise.
Compatibility
Compatibility is a crucial factor when selecting a CPU cooler. The Thermalright Assassin X 120R is compatible with various CPU sockets, including AM4, AM5, and Intel LGA1700/1151/1200, making it versatile for different builds. It is especially suitable for users who are looking to cool high-performance CPUs. Meanwhile, the AXP90 X47 also supports a range of sockets, including Intel LGA 1150/1151/1200/1700 and AMD AM4/AM5. Its low-profile design allows it to fit in smaller cases while still providing excellent cooling potential, making it a strong contender for compact PCs.
Build Quality
Both coolers showcase impressive build quality, but they utilize different materials. The Thermalright Assassin X 120R employs industrial-grade PBT+PC materials, combined with an S-FDB bearing that reduces fan blade shaking. This ensures durability and reliable performance over time. In contrast, the AXP90 X47 features a pure copper base, which enhances heat conductivity and overall cooling efficiency. Additionally, it includes a plating anti-oxidation protective layer to prevent corrosion. While both coolers are well-constructed, the choice may come down to personal preference regarding materials and their associated benefits.
Price Comparison
In terms of pricing, the Thermalright Assassin X 120R is currently priced at $22.90, while the AXP90 X47 is available for $33.99. This makes the Assassin X 120R about 17% cheaper than the AXP90 X47. For budget-conscious consumers or those building multiple systems, the lower price point of the Assassin X 120R may be particularly attractive, especially considering its robust performance capabilities.
User Experience
User experience can vary based on personal needs and system configurations. The Thermalright Assassin X 120R is designed for users who want a balance of aesthetics and performance, with its ARGB lighting and efficient cooling. On the other hand, the AXP90 X47 is tailored for those who prioritize space-saving solutions without compromising on cooling efficiency. Both products have received positive feedback for their performance, but users should consider their specific requirements, such as case size and noise tolerance.
Which should you buy?
In conclusion, choosing between the Thermalright Assassin X 120R and the AXP90 X47 ultimately depends on your individual needs. If you are looking for a cooler that offers excellent performance with stylish aesthetics for a standard case, the Assassin X 120R is the way to go. However, if you need a compact solution for a small form factor build without sacrificing cooling capabilities, the AXP90 X47 stands out as the best option. Both coolers have their strengths, ensuring that there is a suitable choice for a variety of PC setups.
