Introduction to Thermalright CPU Coolers
In the realm of CPU cooling solutions, Thermalright has established itself as a reputable brand with over 20 years of experience. This article compares two of their popular models: the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler and the Thermalright AXP120-X67 Black ARGB Low Profile CPU Air Cooler. With prices at C$46.90 and C$38.79 respectively, we'll delve into their specifications, performance, and overall value.
Design and Dimensions
The Thermalright Peerless Assassin 120 SE features a double tower design with dimensions of 125mm x 135mm x 155mm, making it a robust option for those seeking high-performance cooling. In contrast, the AXP120-X67 is designed for tight spaces, boasting a low profile height of just 67mm, with overall dimensions of 123.5mm x 120mm x 67mm. The compact design of the AXP120-X67 allows it to fit into smaller cases, which is a significant advantage for users with limited space. This makes the AXP120-X67 more versatile for various setups, while the Peerless Assassin shines in larger builds requiring superior cooling capabilities.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin 120 SE offers a maximum air flow of 66.17 CFM with a noise level not exceeding 25.6 dB(A). The dual tower design and six heat pipes contribute to its impressive TDP range of 120 to 245W, making it suitable for high-performance CPUs. On the other hand, the AXP120-X67 also employs six heat pipes and achieves an air flow of 59 CFM, but with a slightly higher noise level of 26.1 dB(A). While both coolers utilize the AGHP technique to manage heat effectively, the Peerless Assassin stands out with a higher cooling capacity, making it the better choice for overclocking scenarios.
Fan Specifications
The Thermalright Peerless Assassin is equipped with two PWM fans, each spinning at 1500 RPM, whereas the AXP120-X67 features a single PWM fan that operates at a slightly higher speed of 1800 RPM. However, the lower profile fan on the AXP120-X67 is only 15mm thick, compared to the 25mm thickness of the fans on the Peerless Assassin. This thin design helps maintain low noise levels but may compromise on overall air flow and cooling efficiency. The choice between these fans ultimately depends on your preference for noise versus cooling performance, but the Peerless Assassin has the edge in air flow and larger fan size.
Installation and Compatibility
Both coolers offer compatibility with a range of Intel and AMD sockets. The Peerless Assassin supports Intel 115X/1200/1700 and AMD AM4 sockets, while the AXP120-X67 is compatible with a broader range of Intel sockets including 1700, 1150, and 2066, as well as AMD AM4. Installation is made easier for both models thanks to the included metal fasteners designed for various platforms. However, the Peerless Assassin’s dual tower design may require more space during installation, while the slim profile of the AXP120-X67 allows for easier manoeuvrability in cramped cases.
Aesthetics and ARGB Features
Aesthetically, both coolers come with ARGB lighting, enhancing the visual appeal of any build. The Peerless Assassin boasts colourful and gorgeous ARGB light effects, which can create an eye-catching ambiance in your setup. The AXP120-X67 also features ARGB but comes with a dedicated 5V 3-pin ARGB port for easy connectivity. While both models offer stylish designs, the choice boils down to personal preference regarding the intensity and style of the RGB effects.
Pricing and Value for Money
The Thermalright Peerless Assassin 120 SE is priced at C$46.90, while the AXP120-X67 is more budget-friendly at C$38.79. The price difference of C$8.11 could be justified by the superior cooling performance, larger size, and dual fan setup of the Peerless Assassin. However, for users with smaller cases or those who do not plan to overclock, the AXP120-X67 provides excellent value with its lower price point and sufficient cooling capabilities for regular use.
User Experience and Feedback
Feedback on both coolers has generally been positive, with users praising the cooling performance of the Peerless Assassin, especially in high-load situations. Its ability to handle high TDP makes it a favourite among gamers and overclockers. Meanwhile, the AXP120-X67 is appreciated for its compact size and efficiency in smaller builds, making it a solid choice for users who prioritize space over extreme performance. Both models reflect Thermalright’s commitment to quality, but user preferences will vary based on individual needs and system configurations.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE and the AXP120-X67 largely depends on your specific requirements. If you need a high-performance cooler with greater cooling capacity for overclocking and larger builds, the Peerless Assassin, priced at C$46.90, is worth the investment. However, for those with space constraints or who are looking for a more budget-friendly option, the AXP120-X67 at C$38.79 offers adequate cooling performance and versatility. Ultimately, both coolers are solid choices, but your final decision should be guided by your cooling needs, case dimensions, and budget.
