Overview of the Thermalright AXP90 X36 Black and Thermalright Assassin X 120R Digital ARGB

The Thermalright AXP90 X36 Black Low Profile CPU Air Cooler and the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler are two distinct offerings from the same brand, catering to different needs. With prices at C$26.90 and C$32.90 respectively, the AXP90 X36 is more budget-friendly, while the Assassin X 120R presents additional features that may justify its higher cost. Each cooler targets users seeking efficient thermal management for their CPUs, but they differ significantly in design and functionalities.

Design and Build Quality

The design of the Thermalright AXP90 X36 is tailored for low-profile applications, making it ideal for compact builds. Its low height allows it to fit in tighter spaces without compromising cooling efficiency. On the other hand, the Assassin X 120R stands taller at 151mm, featuring a symmetrical all-aluminum fin design that enhances its cooling performance. This height provides a larger heat dissipation area, which is critical for high-performance CPUs. While both coolers are robustly built, the AXP90 X36 is designed for size-constrained setups, whereas the Assassin X 120R offers a more substantial presence that may appeal to gamers and enthusiasts.

Cooling Performance

Cooling performance is a key factor when selecting a CPU cooler, and both the AXP90 X36 and the Assassin X 120R excel in this area but in different ways. The AXP90 X36's low-profile design limits its overall cooling capacity compared to the larger Assassin X 120R. The Assassin X 120R boasts a fan speed of 2000 RPM and an air volume of 70.84 CFM, providing powerful cooling and efficiently managing CPU temperatures. Moreover, it has a wind pressure rating of 2.63 MM H2O, demonstrating its ability to push air effectively through its heatsink. Therefore, if maximum cooling performance is a priority, the Assassin X 120R is the superior choice.

Noise Levels

When considering a CPU cooler, noise levels are often a significant concern for users seeking a quieter computing environment. The Thermalright AXP90 X36 does not specify its noise levels, which may imply that it operates quietly, especially given its low-profile design. In contrast, the Assassin X 120R has an operating noise of ≤ 29.8 dB(A), which is relatively quiet for a cooler of its size and performance capability. This means that while both coolers aim for efficient operation, the Assassin X 120R provides a quantifiable metric for users concerned about noise, assuring a calm computing experience.

Aesthetics and RGB Features

Aesthetics can be an important aspect for many users, especially in builds with transparent cases. The Thermalright Assassin X 120R incorporates ARGB (Addressable RGB) lighting, allowing for light synchronisation with the motherboard's 5V 3-pin connector. This feature not only enhances the visual appeal of the cooler but also provides a dynamic lighting experience that can complement other components in a gaming setup. In contrast, the AXP90 X36 lacks any RGB features, making it a more utilitarian choice. Thus, for users prioritising aesthetics alongside functionality, the Assassin X 120R is the clear winner.

Compatibility

Both the Thermalright AXP90 X36 and the Assassin X 120R support a wide range of CPU sockets, making them versatile options for various builds. The Assassin X 120R is explicitly designed to be compatible with Intel's 14th and 15th generation processors, as well as AMD Ryzen 7000 series CPUs, ensuring broad compatibility across different platforms. While the AXP90 X36 is also compatible with various processors, specific details regarding its compatibility are not provided. The Assassin X 120R's detailed compatibility information gives users confidence in their purchasing decision, especially those looking to upgrade their existing systems.

Installation Process

The installation process can often determine the user experience with any CPU cooler. The Thermalright Assassin X 120R comes with installation accessories and instructions to simplify the setup, making it accessible even for less experienced builders. The cooler also mentions the need to use the original backplate of the motherboard for AMD installations, which is an important detail for those with AMD systems. The AXP90 X36, while lacking explicit installation details, is expected to be straightforward given its low-profile design. However, without concrete specifications, users may find the Assassin X 120R's provided support more reassuring.

Price Comparison

In terms of pricing, the Thermalright AXP90 X36 is available at a more economical C$26.90, making it an attractive option for budget-conscious users. The Thermalright Assassin X 120R, priced at C$32.90, reflects its advanced features, such as ARGB lighting and superior cooling performance. Users must consider their specific needs and budget when choosing between these two coolers. If cost is the primary concern and the build allows, the AXP90 X36 is a solid choice, but for those who can invest a bit more for enhanced features, the Assassin X 120R presents good value.

Which should you buy?

In conclusion, the choice between the Thermalright AXP90 X36 Black Low Profile CPU Air Cooler and the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler largely depends on individual needs and preferences. If you require a compact, budget-friendly cooler for a small build, the AXP90 X36 is a sensible choice. Conversely, if you seek superior cooling performance combined with aesthetic appeal and are willing to pay a little extra, the Assassin X 120R is the better option. Ultimately, both coolers have their unique strengths, making them suitable for different types of users in the CPU cooling market.
