Overview of the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler
The Thermalright Assassin X 120R Digital ARGB Black CPU Cooler is priced at $24.90 and offers a robust cooling solution with a digital screen for monitoring system parameters. It features a unique design that combines heat dissipation with an aesthetic appeal, making it an attractive option for gamers and PC enthusiasts alike.
This cooler stands out due to its top cover digital screen that displays CPU temperature, usage, and graphics card metrics. With a height of 151mm, it's designed to fit in most cases while providing ample cooling performance through its aluminum construction and a high-speed fan that operates at 2000RPM. Its compatibility with various Intel and AMD sockets enhances its versatility, making it suitable for a wide range of builds.
Overview of the Thermalright AXP90 X36 Low Profile ITX CPU Cooler
In contrast, the Thermalright AXP90 X36 Low Profile ITX CPU Cooler is a compact option priced at $20.39, making it about 17% cheaper than the Assassin X 120R. With a total height of only 36mm, this cooler is specifically designed for small form factor builds, providing an excellent cooling solution without taking up too much space.
This cooler utilizes four 6mm heat pipes and a slim PWM fan that produces minimal noise levels of 22.4 DBA, ensuring a quieter operation. Its all-metal platform with a corrosion-resistant nickel plating enhances durability, while its adaptability to both Intel and AMD sockets makes it a flexible choice for ITX builds. The AXP90 X36 prioritizes space efficiency without compromising on cooling performance.
Cooling Performance Comparison
When it comes to cooling performance, the Thermalright Assassin X 120R Digital ARGB excels with its robust design that features a 2000RPM fan and a large heat dissipation area due to its 151mm height. This allows it to efficiently manage heat even under heavy workloads, making it suitable for high-performance gaming and demanding applications.
On the other hand, the AXP90 X36, while offering decent cooling with its four heat pipes, operates at a lower maximum RPM and is designed for smaller builds. Its cooling performance is sufficient for most ITX systems but may not match the sheer cooling power of the Assassin X 120R in more demanding scenarios. Thus, for users prioritizing performance in a standard case, the Assassin X 120R is likely the better choice.
Noise Levels and Operation
Noise levels are crucial for many users, especially those who value a quiet computing experience. The Thermalright AXP90 X36 operates at a quieter noise level of 22.4 DBA, which is significantly lower than the Assassin X 120R's maximum operational noise of 29.8 DBA. This makes the AXP90 X36 more suitable for environments where minimal noise is a priority, such as home offices or quiet gaming setups.
However, the Assassin X 120R's noise level is still relatively low and manageable, particularly given its higher cooling capacity. Users who require intense cooling performance might find the slight trade-off in noise acceptable, especially during high-load scenarios. Ultimately, if absolute silence is a goal, the AXP90 X36 is the clear winner.
Aesthetic Appeal and Design Features
The aesthetic features of the Thermalright Assassin X 120R Digital ARGB make it a standout choice for users who appreciate visual flair in their builds. The digital screen not only provides real-time monitoring of CPU and GPU stats but also enhances the overall look of a gaming rig. Its design integrates well with modern setups, especially those that feature RGB lighting.
In contrast, the AXP90 X36 leans towards a more utilitarian design. While it may lack the visual elements of the Assassin X 120R, its compact size and solid build quality make it an excellent choice for users who prioritize function over form. The aesthetic difference will come down to personal preference—whether the user values performance metrics display and RGB lighting or a sleek, minimalistic profile.
Installation and Compatibility
Both coolers offer good compatibility with a range of Intel and AMD sockets, but their installation processes may vary. The Assassin X 120R supports a broader range of Intel sockets, including LGA 1851 and 1700, alongside AMD's AM4 and AM5. Its larger size does mean that users will need to ensure sufficient space within their cases.
The AXP90 X36's low-profile design makes it exceptionally easy to integrate into compact builds, which can be a significant advantage for users focused on ITX systems. It supports the same Intel and AMD sockets, but its smaller footprint allows for easier installation in tighter spaces. Thus, for those prioritizing ease of installation in small form factors, the AXP90 X36 is preferable.
Price Comparison
Price is always a significant factor when making a purchasing decision. The Thermalright Assassin X 120R is priced at $24.90, while the AXP90 X36 is more budget-friendly at $20.39. This pricing difference of about $4.51 makes the AXP90 X36 an attractive choice for users looking to save money without sacrificing too much on performance.
While the Assassin X 120R offers advanced features like a digital display, the AXP90 X36's lower price and compact design can appeal to budget-conscious consumers or those who do not require extensive cooling capabilities. The price point may sway users depending on their specific needs and system requirements.
Which should you buy?
Choosing between the Thermalright Assassin X 120R Digital ARGB and the AXP90 X36 ultimately depends on your specific needs and preferences. If you require superior cooling performance, aesthetic appeal, and real-time monitoring features, the Assassin X 120R is the better option despite its higher price. Conversely, if you're looking for a cost-effective, compact solution for a small form factor build, the AXP90 X36 is an excellent choice that offers solid performance with less noise. Consider your system's requirements and your budget to make the best decision for your cooling needs.
