Overview of the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler

The Thermalright Assassin X 120R is priced at $24.90, making it an attractive entry point for those looking for solid CPU cooling performance. It features a digital screen top cover that displays vital information about CPU and GPU temperatures and usage, enhancing user experience and functionality. The cooler is compatible with a variety of sockets including Intel LGA 1851/1700/115X/1200 and AMD AM4/AM5, providing versatility for different builds.

This model boasts a height of 151mm and utilizes a 120mm PWM fan that can reach speeds of up to 2000 RPM, combined with four heat pipes to effectively dissipate heat. The design not only enhances thermal performance but also incorporates aesthetic elements with its ARGB lighting, making it a visually appealing addition to any setup.

Overview of the Thermalright AXP120-X67 Low Profile CPU Air Cooler

The Thermalright AXP120-X67 is priced at $27.99, presenting a slightly higher investment compared to the Assassin X 120R. This low-profile CPU cooler stands at only 67mm, making it an excellent choice for compact builds or cases with limited space. It features a 120mm PWM fan capable of operating at speeds up to 1800 RPM, providing a balance between cooling efficiency and noise levels, which can reach a maximum of 26.1 dB(A).

With six heat pipes and a design that addresses the inverse gravity effect, the AXP120-X67 promises reliable thermal management in various orientations. Its compatibility extends to Intel's LGA 1700/115X series and AMD's AM4 sockets, ensuring a broad range of compatibility for modern CPUs.

Design and Aesthetics

The design of the Thermalright Assassin X 120R is characterized by its digital screen top cover, which not only serves a functional purpose by displaying real-time temperature data but also adds a modern touch to your PC setup. The cooler features a sleek aluminum finish and ARGB lighting that can sync with your motherboard, creating a visually cohesive environment that enhances aesthetic appeal.

In contrast, the Thermalright AXP120-X67, while more understated, is designed for functionality. Its low-profile height makes it less obtrusive, particularly in cramped spaces, and it retains a clean look with a focus on practicality. Although it lacks the digital features of the Assassin X 120R, its solid construction and efficient airflow design make it a reliable choice for users prioritizing performance over flashy appearances.

Cooling Performance

The cooling performance of the Thermalright Assassin X 120R is impressive, with a fan speed of up to 2000 RPM and an airflow rating of 70.84 CFM. This ensures efficient heat dissipation, making it suitable for high-performance CPUs under load. The four heat pipes enhance its ability to transfer heat away from the CPU, maintaining optimal temperatures during demanding tasks.

On the other hand, the Thermalright AXP120-X67, with its six heat pipes, also offers competitive cooling performance, although with a slightly lower airflow rating of 59 CFM. While it operates at a lower maximum RPM of 1800, its design effectively manages heat, especially in tight spaces. Users can expect reliable cooling, though the performance might not match the higher airflow capabilities of the Assassin X 120R under extreme conditions.

Noise Levels

Noise levels are a crucial consideration for many PC builders. The Thermalright Assassin X 120R operates at a maximum noise level of 29.8 dB(A) when under full load, which is relatively quiet for a cooler of its performance caliber. This makes it suitable for users who prefer a quieter working environment, especially in gaming or content creation scenarios.

In comparison, the AXP120-X67 excels in this category, with a maximum noise level of only 26.1 dB(A). This means it operates even more quietly, making it an excellent choice for users who are particularly sensitive to noise, like those building a home theater PC or a silent workstation.

Installation and Compatibility

Both coolers offer straightforward installation processes, but the Thermalright Assassin X 120R stands out with its wide compatibility across multiple platforms, supporting both Intel and AMD sockets. It comes with installation accessories and a guide, ensuring that users can set it up without significant hassle.

The AXP120-X67 also provides solid compatibility and includes metal fasteners for both Intel and AMD platforms. However, its low-profile design might limit compatibility with certain cases, particularly those that are not specifically designed for compact components. Users need to consider their case specifications carefully when opting for this cooler.

Price and Value Comparison

When comparing prices, the Thermalright Assassin X 120R is priced at $24.90, making it about 11% cheaper than the AXP120-X67, which retails for $27.99. This price difference may influence buyers who are looking for effective cooling solutions without breaking the bank.

Both models offer great value in terms of performance, but the Assassin X 120R's additional features, such as the digital screen and higher airflow, might justify its slightly lower price for those who prioritize enhanced functionality and aesthetics in their builds.

Which should you buy?

Choosing between the Thermalright Assassin X 120R and the AXP120-X67 ultimately depends on your specific needs and preferences. If you are looking for a cooler with advanced features like a digital display and ARGB lighting, along with superior airflow and cooling performance, the Assassin X 120R is the better choice at $24.90.

However, if you need a low-profile solution that operates quietly and fits in tighter spaces, the AXP120-X67, priced at $27.99, could be the ideal fit. Both offer great cooling capabilities, but your choice should align with your budget, case compatibility, and aesthetic preferences.
