Thermalright Assassin X 120R SE V2 CPU Cooler, 4× vs Thermalright AXP90 X47 Full Low Profile CPU Cooler,

Design and Dimensions

The Thermalright Assassin X 120R SE V2 CPU Cooler is significantly larger than the Thermalright AXP90 X47 Full Low Profile CPU Cooler. The Assassin X 120R has dimensions of 120mm x 71mm x 148mm, while the AXP90 measures just 97mm x 92mm x 47mm. This means the Assassin X 120R stands nearly three times taller than the AXP90, making it a better fit for mid-sized cases but potentially obstructive in compact builds.

The low profile design of the AXP90 makes it ideal for small form factor (SFF) cases, which are becoming increasingly popular among gamers and PC builders seeking portability. Its compact height of only 47mm allows it to fit comfortably in tight spaces, unlike the taller Assassin X 120R, which might limit compatibility with smaller cases.

Cooling Performance

When it comes to cooling performance, the Thermalright Assassin X 120R is equipped with 4 heat pipes and a 120mm PWM fan that operates at a maximum speed of 1550 RPM, delivering an airflow of 66.17 CFM. This is considerably higher than the AXP90's 92mm fan, which provides an airflow of 42.58 CFM at a noise level of 22.4 dB(A).

While the AXP90’s low-profile design sacrifices some cooling efficiency for size, the Assassin X 120R is designed to maximize heat dissipation with its larger fan and heat sink. The noise level of the Assassin X 120R is also rated at ≤25.6 dB(A), which, while slightly louder than the AXP90, still promises a quiet operation, especially under load.

Compatibility

Both coolers are compatible with a variety of Intel and AMD sockets, but the Assassin X 120R offers broader compatibility with additional Intel sockets such as LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, and LGA1700. It also supports the latest AMD AM4 and AM5 sockets. In contrast, the AXP90 supports Intel LGA1150, LGA1151, LGA1200, and LGA1700, along with AMD AM4 and AM5.

This wider compatibility makes the Assassin X 120R a more versatile choice for users who might be building or upgrading systems with different socket types. If you are planning for future upgrades, the Assassin X 120R offers more flexibility in that regard.

Noise Level

The Thermalright Assassin X 120R operates at a maximum noise level of ≤25.6 dB(A), which is relatively quiet for a cooler of its size and performance capabilities. Meanwhile, the AXP90 boasts an even lower noise level of 22.4 dB(A), thanks to its smaller fan operating at lower speeds.

For users who prioritize a silent PC experience, the AXP90 may be the preferable option. However, the difference in noise levels is not substantial enough to be a deciding factor for most users, especially considering the superior cooling performance of the Assassin X 120R.

Build Quality and Features

Both coolers are constructed with quality materials, but the Assassin X 120R features a pure copper base and aluminum heat sink, while the AXP90 is made from pure copper with a plating anti-oxidation protective layer. This means that the AXP90 has enhanced corrosion resistance, which can be an important factor for long-term use.

The Assassin X 120R comes with S-FDB bearings, which help to minimize noise while maximizing cooling performance. It also features addressable RGB lighting, which adds an aesthetic appeal to builds. The AXP90, on the other hand, focuses on compactness and efficiency but lacks RGB features, making it less visually striking.

Price Comparison

The Thermalright Assassin X 120R is priced at $16.59, while the AXP90 is significantly more expensive at $33.99. This means the AXP90 is about 105% more expensive than the Assassin X 120R.

For budget-conscious consumers or those building a system without specific space constraints, the Assassin X 120R offers excellent value for its performance. However, if you are specifically looking for a low-profile cooler and are willing to pay a premium for compactness, the AXP90 might justify its higher price.

User Experience

While both products are well-regarded, the larger size and better cooling capabilities of the Thermalright Assassin X 120R often make it a favorite among users with sufficient case space. The installation is straightforward with mounting kits provided for both Intel and AMD sockets, making it accessible for novice builders.

On the other hand, the AXP90 is praised for its ease of installation in small form factor builds. However, its cooling performance may not meet the needs of high-performance CPUs, which could lead to thermal throttling during intense workloads. Users seeking a balance of performance in compact builds will find the AXP90 a worthy option, though it has its limitations.

Which should you buy?

Choosing between the Thermalright Assassin X 120R and the AXP90 X47 depends heavily on your specific needs. If you prioritize superior cooling performance and compatibility with a wider range of socket types, the Assassin X 120R is the clear winner, especially with its competitive price of $16.59.

Conversely, if you're working with a compact case and need a low-profile solution, the AXP90 may be worth the investment at $33.99, despite its lesser cooling capabilities. Ultimately, the decision hinges on whether you prioritize performance or size in your PC build.
