The difference of C$2.61 may seem minimal, but it reflects the distinct features and designs of both products. For budget-conscious buyers, the Assassin X 120 SE offers a compelling option without sacrificing quality.
Design and Aesthetics
The Thermalright AXP90 X36 boasts a sleek, low-profile design, ideal for compact builds where space is limited. In contrast, the Thermalright Assassin X 120 SE features a more traditional tower design, which can appeal to users looking for a striking appearance enhanced by its ARGB lighting. The choice between these two designs ultimately depends on personal preference and the specific requirements of your PC case.
Cooling Performance
Cooling performance is essential for maintaining optimal CPU temperatures, and both coolers deliver impressive results. The Thermalright Assassin X 120 SE is designed for TDP (Thermal Design Power) of 125 to 225W, making it suitable for a wide range of CPUs, while the AXP90 X36's cooling capabilities are not explicitly stated. However, the Assassin X 120 SE's use of 4×6mm heat pipes and efficient PWM fans indicates superior cooling efficiency, especially in high-performance scenarios.
Noise Level
Noise levels can significantly impact user experience, especially in quiet environments. The Thermalright Assassin X 120 SE operates at a maximum noise level of 25.6 dB(A), making it a quiet option for users who prioritise a serene computing experience. The AXP90 X36 does not specify its noise levels, leaving potential buyers in the dark regarding its acoustic performance. Thus, if silence is golden for you, the Assassin X 120 SE may be the better choice.
Compatibility
Compatibility is a crucial factor when selecting a CPU cooler. The Thermalright Assassin X 120 SE supports a wide range of sockets, including Intel’s 115X, 1200, 1700, and AMD's AM4. This extensive compatibility ensures that it will work with a variety of systems, making it a versatile option. The AXP90 X36 does not provide specific compatibility details, which could limit its appeal to users with particular CPU setups.
Build Quality and Durability
Build quality can affect the longevity and reliability of CPU coolers. The Thermalright Assassin X 120 SE is engineered with industrial-grade materials and features S-FDB bearings, which contribute to a service life of up to 20,000 hours. This durability is an essential consideration for users who want a cooler that will last through multiple builds or upgrades. The AXP90 X36's build quality remains unspecified, leaving uncertainties regarding its long-term performance.
Brand Reputation
Thermalright has established itself as a reputable brand with over 20 years of experience in the industry. Known for its focus on research and development in computer accessories, Thermalright has garnered a loyal following among enthusiasts. Both the AXP90 X36 and the Assassin X 120 SE benefit from this brand reputation. However, the Assassin X 120 SE’s detailed specifications and features might appeal more to users looking for a dependable choice backed by proven technology.
Which should you buy?
Ultimately, the choice between the Thermalright AXP90 X36 Black Low Profile CPU Air Cooler and the Thermalright Assassin X 120 SE ARGB CPU Air Cooler hinges on your specific needs. If aesthetics and robust cooling performance are your primary concerns, the Assassin X 120 SE is the superior option, especially given its lower price of C$24.29 and extensive compatibility. However, if you require a low-profile design for a compact build and are willing to compromise on some specifications, the AXP90 X36 at C$26.90 could still meet your needs.
