Dimension comparison
Overview of Thermalright CPU Coolers
In the competitive world of CPU coolers, Thermalright has established itself as a reputable brand, boasting over 20 years of development. The two coolers being compared, the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright AXP120-X67 Black ARGB Low Profile CPU Air Cooler, both showcase the brand’s commitment to quality and performance. The Assassin X 120 SE is priced at C$24.29, while the AXP120-X67 comes in at C$38.79, making the former a more budget-friendly option.
Design and Dimensions
The design and dimensions of a CPU cooler can significantly influence its compatibility with various builds. The Thermalright Assassin X 120 SE measures 125(L)x71(W)x148(H)mm, while the AXP120-X67 has slightly smaller dimensions of 123.5(L)x120(W)x67(H)mm. This makes the AXP120-X67 a low-profile cooler, standing at only 67mm tall, which is ideal for compact builds. The weight of the Assassin X 120 SE is 0.645kg, making it relatively lightweight, while the materials used in both coolers—aluminium and copper—contribute to their effective heat dissipation capabilities.
Performance and Cooling Efficiency
Cooling performance is a critical factor for any CPU cooler, and here the two models have distinct characteristics. The Assassin X 120 SE is designed to handle a TDP (Thermal Design Power) of 125 to 225W, which allows it to efficiently cool high-performance CPUs. It features a PWM fan with a maximum airflow of 66.17 CFM and operates at a noise level of 25.6 dB(A). In contrast, the AXP120-X67 is equipped with a PWM fan that delivers a maximum airflow of 59 CFM at a slightly higher noise level of 26.1 dB(A). While both coolers are effective, the Assassin X 120 SE provides a higher airflow rate, suggesting better cooling potential under heavy loads.
Fan Specifications
The fan specifications of a CPU cooler can greatly influence its overall efficiency and noise levels. The Thermalright Assassin X 120 SE features a 120mm fan that operates at a speed of 1550 RPM, while the AXP120-X67's fan spins at 1800 RPM, albeit with a slightly lower airflow. The Assassin X 120 SE's fan achieves a balance of quiet operation and effective cooling with a noise level of 25.6 dB(A). On the other hand, the AXP120-X67, despite its higher RPM, compromises on airflow, demonstrating the delicate trade-off between speed and noise.
Installation and Compatibility
Both coolers are designed for easy installation and compatibility across various platforms. The Thermalright Assassin X 120 SE supports Intel sockets 115X, 1200, 1700, and AMD AM4, while the AXP120-X67 is compatible with a wider array of Intel sockets, including 1700, 1150, 1151, 1155, 1156, 1200, 2011, and 2066. This broader compatibility of the AXP120-X67 may appeal to users with older Intel systems. Both models come with the necessary mounting hardware, ensuring a straightforward installation process, which is crucial for users looking to upgrade their cooling solution without hassle.
Noise Levels
When considering a CPU cooler, noise levels can be a decisive factor, especially for users aiming for a quiet computing experience. The Thermalright Assassin X 120 SE operates at a maximum noise level of 25.6 dB(A), making it a quieter option compared to the AXP120-X67, which reaches up to 26.1 dB(A). While the difference is minimal, it could be noticeable in a silent build. Therefore, users prioritizing a quieter operation may lean towards the Assassin X 120 SE.
Aesthetic Appeal
In addition to performance, aesthetics play a role in a CPU cooler's appeal. Both coolers feature ARGB (Addressable RGB) lighting, allowing users to customize their setups with vibrant colours. The AXP120-X67 boasts a sleek black finish and a low-profile design, which can complement compact builds nicely. The Assassin X 120 SE, while slightly bulkier, also includes ARGB features that enhance its visual appeal.
