Overview of Thermalright CPU Coolers

The Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Thermalright AXP120-X67 Low Profile CPU Air Cooler are both designed to deliver efficient cooling solutions for CPU enthusiasts. With a brand reputation built over 20 years in the market, Thermalright has established itself as a reliable name in CPU cooling solutions. The Assassin X 120R SE V2 retails for C$23.59, while the AXP120-X67 is priced at C$36.90, making the former a more budget-friendly option.

Design and Dimensions

In terms of design, the Assassin X 120R SE V2 stands at a height of 148mm, which makes it suitable for medium-sized computer cases without obstructing the overall memory installation. On the other hand, the AXP120-X67 boasts a more compact height of 67mm, ideal for low-profile setups where space is limited. The dimensions of the AXP120-X67 are 123.5mm in length and 120mm in width, making it a versatile choice for smaller builds.

Cooling Performance

Cooling performance is a focal point for both coolers. The Assassin X 120R SE V2 features a PWM fan with a maximum airflow of 66.17 CFM and operates at a noise level of 25.6 dB(A), while the AXP120-X67 has a slightly lower maximum airflow of 59 CFM and a marginally higher noise level of 26.1 dB(A). The Assassin X 120R SE V2 can achieve a maximum fan speed of 1550 RPM, compared to the AXP120-X67's maximum speed of 1800 RPM. Despite the AXP120-X67's higher RPM, the Assassin X 120R SE V2 provides a better airflow-to-noise ratio, making it a more efficient choice for quiet operation.

Compatibility

Both coolers boast impressive compatibility with various CPU sockets. The Assassin X 120R SE V2 supports a wide range of Intel sockets including LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, and LGA1700, as well as AMD sockets such as AM4 and AM5. In comparison, the AXP120-X67 supports Intel sockets including LGA1700, LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA2011, and LGA2066, alongside AMD AM4. This makes both coolers highly versatile, but the AXP120-X67 offers support for additional Intel sockets, giving it a slight edge in compatibility.

Build Quality and Materials

Quality and longevity are vital when it comes to CPU coolers. The Assassin X 120R SE V2 utilises a heat pipe design with 4×6mm heat pipes, applying AGHP technology to prevent the inverse gravity effect. It also uses S-FDB bearings, ensuring a service life of up to 20,000 hours. Meanwhile, the AXP120-X67 features 6×6mm heat pipes and a full electroplating reflow welding process for enhanced durability. The use of aluminum fins on a copper base further optimises heat dissipation. While both products demonstrate quality construction, the AXP120-X67's slightly advanced materials and techniques may offer better long-term reliability.

Fan Specifications

The fans are a crucial aspect of both coolers' performance. The Assassin X 120R SE V2 utilises a 120mm fan with a thickness of 25mm, while the AXP120-X67 also employs a 120mm fan but is slimmer at 15mm. Despite the difference in thickness, the AXP120-X67's fan can achieve a higher RPM of 1800, compared to the Assassin's 1550 RPM. However, the additional thickness of the Assassin's fan may contribute to better airflow and cooling under sustained loads, particularly in standard setups.

Noise Levels

Noise levels are an important consideration for users looking for a quiet computing experience. The Assassin X 120R SE V2 is rated at a noise level of 25.6 dB(A), while the AXP120-X67 has a noise level of 26.1 dB(A). Although both are relatively quiet, the Assassin X 120R SE V2 has a slight advantage, making it the better choice for those sensitive to noise. This lower noise level, combined with its higher airflow, positions it well for users seeking a balance between performance and quiet operation.

Which should you buy?

Deciding between the Thermalright Assassin X 120R SE V2 and the Thermalright AXP120-X67 ultimately depends on your specific needs. The Assassin X 120R SE V2 is a more affordable option at C$23.59, offering superior airflow and quieter operation, making it a great choice for standard builds. Conversely, the AXP120-X67, priced at C$36.90, is ideal for compact cases where space is a premium and offers a broader compatibility range. If you value quiet performance and airflow, the Assassin X 120R SE V2 is the better pick. However, for users with smaller setups who require low-profile cooling, the AXP120-X67 would be the suitable choice.
