Overview of Thermalright AXP90 X53

The Thermalright AXP90 X53 is a low-profile cooler designed for compact builds, priced at C$45.99. With a height of just 53mm, it is particularly suited for small form factor cases. The cooler features a 92mm slim PWM fan capable of reaching speeds up to 2700 RPM, which significantly enhances its cooling performance despite its small size.

Thermalright has incorporated its AGHP technology into the AXP90 X53, effectively doubling heat transfer efficiency. This advanced design addresses the inverse gravity effect, making it versatile for both vertical and horizontal orientations. Broad compatibility with Intel and AMD CPU sockets, including LGA1700 and AM4, ensures that it can fit a wide range of motherboards, making it a flexible choice for various builds.

Overview of Thermalright Assassin X 120R

The Thermalright Assassin X 120R is a larger CPU cooler, retailing at C$32.90, which offers a more robust cooling solution with a height of 151mm. This cooler is equipped with a 120mm fan that operates at a speed of 2000 RPM, providing a solid airflow of 70.84 CFM while maintaining a noise level of up to 29.8 dB(A).

The Assassin X 120R features a sleek design with an ARGB lighting system that syncs with compatible motherboards for a visually appealing setup. Its construction includes symmetrical aluminum fins that enhance heat dissipation, making it suitable for more extensive gaming rigs. This cooler also supports both Intel and AMD platforms, making it a versatile option for users looking to upgrade their CPU cooling.

Cooling Performance Comparison

When it comes to cooling performance, the Thermalright AXP90 X53 offers a maximum fan speed of 2700 RPM, while the Assassin X 120R has a maximum speed of 2000 RPM. This gives the AXP90 X53 an edge in raw airflow potential, but the Assassin X 120R compensates with its larger fan size and increased surface area, offering 70.84 CFM of airflow.

While the AXP90 X53 is designed for low-profile setups, making it effective in small spaces, the Assassin X 120R excels in larger builds where its height can be accommodated. This makes the AXP90 X53 ideal for ITX builds, while the Assassin X 120R is better suited for ATX cases that can support its larger dimensions.

Noise Levels

In terms of operational noise, the Thermalright AXP90 X53 operates quietly, with no specified noise level mentioned in its features, which suggests a focus on silent operation. On the other hand, the Assassin X 120R has a maximum noise level of 29.8 dB(A), which is relatively moderate for a cooling fan of its size and performance.

If you prioritise silence in your build, the AXP90 X53 may be more appealing due to its slim design and emphasis on quiet operation. However, the Assassin X 120R offers a balance of performance and aesthetics with its ARGB lighting, which may justify the slightly higher noise level for users looking for both functionality and style.

Compatibility

The Thermalright AXP90 X53 boasts broad compatibility with various CPU sockets, including Intel’s LGA1700 and AMD’s AM4 and AM5. This makes it a practical choice for users building compact systems with diverse hardware configurations.

In comparison, the Assassin X 120R also supports multiple sockets, including Intel's 14th and 15th Gen CPUs and AMD Ryzen 7000 series. Both coolers come with installation accessories to facilitate set-up, but the AXP90 X53's low profile may allow it to fit in more compact cases, while the Assassin X 120R is limited by its height, making it better suited for standard or larger cases.

Aesthetics and Design

The design of the Thermalright AXP90 X53 is functional, emphasizing its low profile for small builds. It lacks the aesthetic embellishments that some users might prefer. In contrast, the Assassin X 120R incorporates ARGB lighting, which not only enhances the visual appeal but also allows for synchronization with motherboard lighting.

The digital screen on the Assassin X 120R adds an extra layer of interactivity, providing users with visual feedback on temperatures and performance. This focus on aesthetics makes the Assassin X 120R a more attractive option for users who value the look of their build, while the AXP90 X53 prioritises functionality and compactness.

Price Comparison

The Thermalright AXP90 X53 is priced at C$45.99, while the Assassin X 120R is available for a more budget-friendly C$32.90. This price difference may make the Assassin X 120R more appealing to those looking for a cost-effective solution without sacrificing performance.

However, it is essential to consider the specific needs of your build. If you require a low-profile cooler for a compact ITX setup, the AXP90 X53 may justify its higher price. Conversely, for larger builds where aesthetics and a more robust cooling capacity are necessary, the Assassin X 120R offers excellent value for its price.

Which should you buy?

Choosing between the Thermalright AXP90 X53 and the Thermalright Assassin X 120R largely depends on your specific needs. If you’re building a compact ITX system and require a low-profile cooler that excels in tight spaces, the AXP90 X53 is the right choice, offering superior airflow at a slightly higher price.

However, if you are looking for a more traditional cooling solution with enhanced aesthetics and solid performance for a standard ATX build, the Assassin X 120R stands out, especially with its lower price point and additional features like ARGB lighting. Ultimately, weigh your priorities—whether it’s size, performance, aesthetics, or cost—to make the best choice for your setup.
