Thermalright Assassin X 120R SE V2 CPU Air Cooler vs Thermalright AXP90 X47 Full Low Profile CPU Cooler

Overview of Thermalright Products

In the landscape of CPU coolers, the Thermalright Assassin X 120R SE V2 and the Thermalright AXP90 X47 are both compelling options. The Assassin X 120R SE V2 is priced at C$23.59, while the AXP90 X47 comes in at C$43.39. Despite both products being manufactured by Thermalright, their designs and intended use cases differ significantly, making them suitable for various build requirements.

Design and Size

The design and size of a cooler can significantly impact its compatibility with different builds. The Assassin X 120R SE V2 stands at a height of 148mm, making it suitable for medium-sized computer cases. In contrast, the AXP90 X47 is a low-profile cooler with a height of just 47mm, making it ideal for compact builds like HTPCs and ITX setups. This substantial difference in height means that while the Assassin X 120R SE V2 can accommodate larger cases, the AXP90 X47 fits in spaces where traditional coolers cannot.

Cooling Performance

When it comes to cooling performance, the Assassin X 120R SE V2 boasts a fan airflow of 66.17 CFM at a maximum speed of 1550 RPM, which is higher than the AXP90 X47's 42.58 CFM at a fan speed of 2700 RPM. However, the AXP90 X47’s design focuses on low profile efficiency, achieving a noise level of 22.4 dB(A), slightly quieter than the Assassin's ≤25.6 dB(A). Thus, while the Assassin X 120R SE V2 offers better airflow, the AXP90 X47 excels in terms of noise levels, making it a quieter choice.

Technology Features

Both coolers utilize Thermalright’s AGHP technology, which involves the use of 4×6mm heat pipes to enhance heat dissipation. This technique effectively combats the inverse gravity effect, ensuring both coolers perform well in various orientations. The AXP90 X47 enhances this with a secondary welding process on heat pipes and fins, purportedly doubling its cooling effect. This additional technology may give the AXP90 X47 an edge in thermal performance despite its smaller fan size.

Fan Specifications

The fan specifications differ markedly between the two coolers. The Assassin X 120R SE V2 features a standard 120mm PWM fan, while the AXP90 X47 is equipped with a smaller 92mm PWM fan. The larger fan on the Assassin cooler allows for more robust airflow, which might be essential for higher-performance CPUs. Conversely, the smaller fan on the AXP90 X47 is tailored for quieter operation, making it a better choice for users prioritizing low noise over maximum cooling potential.

Compatibility

Both coolers offer broad compatibility with various CPU sockets. The Assassin X 120R SE V2 supports Intel sockets including LGA1150 through LGA1700 and AMD AM4/AM5. The AXP90 X47 also provides support for a similar range of sockets, including Intel LGA1150/1151/1155/1156/1200 and AMD AM4/AM5. This compatibility ensures that both coolers can fit into a wide range of systems, though users with specific CPU models may need to check the mounting plates provided.

Build Quality and Materials

Quality and materials are crucial for ensuring durability and performance. The Assassin X 120R SE V2 is constructed with industrial-grade PBT + PC material, while the AXP90 X47 features a pure copper radiator. The use of pure copper in the AXP90 X47 may offer better heat transfer properties, while the materials used in the Assassin X 120R SE V2 ensure that it can withstand regular usage over time. Users looking for longevity may prefer the additional heat conduction benefits of the AXP90 X47.

Pricing and Value

The pricing of these coolers reflects their intended market segments. The Assassin X 120R SE V2 is significantly more affordable at C$23.59, while the AXP90 X47 is priced at C$43.39. This C$19.80 difference may lead budget-conscious buyers to lean towards the Assassin model, especially for builds that can accommodate its size. However, the AXP90 X47 justifies its higher price with its low-profile design and advanced cooling technology, appealing to users with specific needs.

Which should you buy?

Choosing between the Thermalright Assassin X 120R SE V2 and the AXP90 X47 largely depends on your specific use case. If you have a medium-sized case and prioritize airflow and cooling performance, the Assassin X 120R SE V2 is a strong contender. On the other hand, if you are looking for a compact, quieter solution for a small form factor build, the AXP90 X47 may be the better choice despite its higher price. Ultimately, both coolers reflect Thermalright's commitment to quality and performance, catering to different segments of CPU cooling needs.
