Overview of Thermalright Assassin King 120 SE White ARGB CPU Air Cooler
The Thermalright Assassin King 120 SE White ARGB CPU Air Cooler is priced at $19.82, making it an attractive option for budget-conscious consumers. This cooler features five heat pipes and is designed to provide efficient cooling for a variety of CPU sockets, including Intel LGA1700 and AMD AM4/AM5. Its dimensions are 120mm in length, 73mm in width, and it stands 148mm tall. The cooler utilizes a PWM fan, the TL-C12CW-S, which spins at a maximum speed of 1550 RPM and can generate air flow of up to 66.17 CFM with a noise level of 25.6 dB(A). The ARGB lighting adds an aesthetic touch, appealing to users who value visual components in their builds.
Overview of Thermalright AXP120-X67 Low Profile CPU Air Cooler
The Thermalright AXP120-X67 Low Profile CPU Air Cooler is priced higher at $27.99, approximately 41% more than the Assassin King. Designed for users with space constraints, this cooler has a total height of just 67mm, making it suitable for compact builds. It features six heat pipes and is compatible with a wide range of Intel and AMD sockets, including LGA 1700 and AM4. The TL-C12015 PWM fan operates at a maximum speed of 1800 RPM and provides an air flow of 59 CFM, with a noise level of 26.1 dB(A). This cooler's aluminum and copper construction aims to enhance thermal performance while maintaining a low profile.
Cooling Performance Comparison
In terms of cooling performance, the Thermalright Assassin King 120 SE offers a maximum air flow of 66.17 CFM, compared to 59 CFM from the AXP120-X67. This means the Assassin King could potentially offer better cooling efficiency in optimal conditions. The five heat pipes of the Assassin King also contribute to its cooling capabilities, allowing it to handle thermal loads effectively. However, the AXP120-X67's six heat pipes may provide a slight advantage in heat dissipation, especially in smaller cases where airflow can be limited. Both coolers utilize advanced AGHP techniques to combat gravity effects, but the Assassin King has a slight edge in airflow, which is critical for performance.
Noise Levels and Acoustic Performance
When it comes to noise, the Thermalright Assassin King 120 SE operates at a noise level of 25.6 dB(A), making it a quieter option compared to the AXP120-X67, which has a noise level of 26.1 dB(A). While the difference is marginal, users seeking a quieter computing environment may prefer the Assassin King for its slightly lower noise output. The PWM fans in both coolers are engineered for efficient cooling while minimizing noise, but the Assassin King's fan appears to achieve a fine balance of performance and quiet operation, making it suitable for both gaming and professional use.
Aesthetic Appeal and Build Quality
The Thermalright Assassin King 120 SE features ARGB lighting, providing a customizable and visually appealing option for users who enjoy RGB setups. This can enhance the overall aesthetics of a gaming rig or a build focused on visual design. On the other hand, the AXP120-X67 maintains a more understated look, focusing primarily on performance rather than lighting effects. Both coolers are constructed with quality materials, including aluminum and copper, ensuring durability and efficient heat transfer. However, if aesthetics are a priority, the Assassin King's ARGB feature could be a deciding factor for many users.
Installation and Compatibility
Both coolers are designed for easy installation and wide compatibility. The Thermalright Assassin King 120 SE supports a variety of Intel and AMD sockets, including LGA1700 and AM4/AM5, making it versatile for many builds. Its dimensions of 120(L) x 73(W) x 148(H)mm allow it to fit comfortably in most mid-sized cases. Conversely, the AXP120-X67's low-profile design (120(L) x 120(W) x 67(H)mm) makes it particularly suitable for compact builds, where space is at a premium. Both coolers come with the necessary mounting hardware for easy setup, but the AXP120-X67 may be more appealing for users with smaller cases.
Price Considerations
With the Thermalright Assassin King 120 SE priced at $19.82 and the AXP120-X67 at $27.99, there is a noticeable price difference of about $8.17. This makes the Assassin King approximately 29% cheaper than its counterpart. For budget-conscious users or those looking for the best value for money, the Assassin King presents a compelling choice, especially given its competitive performance metrics. However, those who require a low-profile cooler might find the additional cost of the AXP120-X67 justifiable for its unique advantages.
Which should you buy?
Choosing between the Thermalright Assassin King 120 SE and the AXP120-X67 ultimately depends on your specific needs and budget. The Assassin King offers superior airflow, a lower price, and aesthetic RGB features, making it a great choice for standard builds. Conversely, the AXP120-X67 is ideal for compact setups due to its low-profile design and is slightly more powerful in terms of heat pipe count. If space is not an issue and you want a budget-friendly, visually appealing cooler, go for the Assassin King. However, if you prioritize a low-profile design and are willing to spend a bit more, the AXP120-X67 is worth considering.
