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

The Thermalright Assassin X 120R Digital ARGB Black CPU Cooler is priced at $22.90, offering a robust cooling solution with a performance-level fan speed of 2000 RPM. It features a digital screen on its top cover, enhancing both functionality and aesthetics. This cooler is designed to support various CPU sockets, including AM4, AM5, and Intel's LGA1700/1851/1150/1151/1200. With its 151mm height, it provides effective heat dissipation while being compatible with most PC cases.

Overview of Thermalright AXP90 X36 Low Profile ITX CPU Cooler

The Thermalright AXP90 X36 Low Profile ITX CPU Cooler comes at a lower price of $20.39, making it about 7% cheaper than its competitor. This cooler is designed for low-profile builds, boasting a total height of only 36mm, which is ideal for compact spaces. It is compatible with AMD’s AM4 and AM5, as well as Intel’s LGA1150/1151/1200/1700/1851 sockets. Its compact design does not compromise on quality, featuring a nickel plating process for corrosion resistance.

Cooling Performance Comparison

In terms of cooling performance, the Thermalright Assassin X 120R excels with its 2000 RPM fan speed, which is notable for delivering efficient heat dissipation. Its four heat pipes utilize AGHP technology, enhancing thermal transfer and reducing the impact of gravity. On the other hand, the AXP90 X36, while it has a lower maximum noise level of ≤22.4 DBA, operates at a lower performance level and is designed for compact builds. This means the Assassin X 120R is better suited for high-performance applications, while the AXP90 X36 is more appropriate for small form factor systems.

Design and Aesthetics

The Thermalright Assassin X 120R features an appealing digital ARGB design, allowing users to synchronize the cooler’s lighting effects with their motherboard. This adds a visual flair to any build, particularly for users who prioritize aesthetics. In contrast, the AXP90 X36 focuses on functionality over looks, with a more utilitarian design. While it may not have the same visual impact, its compact size and low profile make it a practical choice for ITX builds where space is limited.

Noise Levels

The Thermalright Assassin X 120R includes silicone corner pads to minimize noise during operation, but its higher RPM can lead to increased noise levels compared to the AXP90 X36. The AXP90 X36, rated at a maximum noise level of ≤22.4 DBA, is designed to be quieter, making it a suitable option for users seeking a silent computing experience. It's crucial to weigh the importance of cooling performance against noise levels when choosing between these two coolers.

Installation and Compatibility

Both the Thermalright Assassin X 120R and AXP90 X36 are designed for easy installation, but they cater to different needs. The Assassin X 120R, with its 151mm height, fits in most cases and is compatible with a wide range of sockets, making it versatile for various builds. Conversely, the AXP90 X36 is specifically intended for low-profile cases, measuring only 36mm in height. This makes it a standout option for users with space constraints, but it may not be suitable for builds requiring high cooling performance.

Price Comparison

The Thermalright AXP90 X36 is priced at $20.39, making it a more cost-effective choice compared to the Assassin X 120R at $22.90. This price difference of about $2.51 (approximately 11%) could influence budget-conscious consumers. While the Assassin X 120R offers enhanced cooling capabilities, for users with limited budgets or specific low-profile needs, the AXP90 X36 presents a compelling option without breaking the bank.

Which should you buy?

Choosing between the Thermalright Assassin X 120R and the AXP90 X36 ultimately depends on your specific needs. If you prioritize cooling performance and aesthetics, the Assassin X 120R is the better option, especially for high-performance systems. However, if you require a compact, low-profile cooler for an ITX build or are looking for a more budget-friendly solution, the AXP90 X36 is a strong contender. Each cooler has its strengths, so consider your build's requirements to make the best choice.
