Overview of the Products
When comparing the Thermalright AXP-120-X67 Black ARGB Low Profile CPU Air Cooler and the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler, both options present unique advantages. The AXP-120-X67 is priced at $32.59, while the Peerless Assassin 120 SE comes in slightly higher at $32.90, making the AXP-120-X67 about 1% cheaper. This slight price difference may influence a budget-conscious buyer, but both coolers offer solid performance features.
Cooling Performance
In terms of cooling performance, the Thermalrlght Peerless Assassin 120 SE has an edge with its dual 120mm TL-C12C PWM fans, which can deliver a maximum airflow of 66.17 CFM at a noise level of 25.6 dB(A). Conversely, the AXP-120-X67 features a single 120mm PWM fan with a maximum airflow of 59 CFM and a noise level of 26.1 dB(A). The Peerless Assassin's dual-fan setup and higher airflow provide better thermal management, especially for overclocked setups or high-performance CPUs.
Design and Build Quality
The design and build quality of both coolers are impressive, yet they differ in their aesthetics and structural design. The AXP-120-X67 has a low-profile design with a total height of 67mm, making it suitable for compact cases. It features an aluminum fin on a copper base and is equipped with six copper heat pipes for efficient heat transfer. On the other hand, the Thermalrlght Peerless Assassin 120 SE has a taller profile of 155mm and a dual-tower heatsink configuration, which enhances its cooling capabilities but may limit compatibility with smaller cases.
Fan Technology
Fan technology plays a crucial role in CPU coolers, and both products leverage PWM fan technology for efficient operation. The AXP-120-X67's TL-C12015B-S fan operates at a speed of 1800 RPM, while the Peerless Assassin's TL-C12C fan runs at 1550 RPM. Despite the lower RPM of the Peerless Assassin, its dual fans compensate by providing a higher overall airflow, which can be beneficial for users needing robust cooling during intensive tasks.
Compatibility
Compatibility is a vital factor for users looking to upgrade their cooling solutions. Both coolers support a wide range of Intel and AMD sockets, including the latest LGA 1700 and AM4/AM5 platforms. The AXP-120-X67 is compatible with various Intel sockets (1700, 1150, 1151, etc.) as well as AMD AM4. The Peerless Assassin 120 SE also supports a similar range but requires users to utilize the motherboard's built-in backplate for installation on AM4 and AM5, which may add an extra step during setup.
Noise Levels
Noise levels are an essential consideration for gamers and professionals alike who prefer a quiet working environment. The Thermalrlght Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A), making it slightly quieter than the AXP-120-X67, which reaches up to 26.1 dB(A). This difference may be minor, but for users sensitive to noise, the Peerless Assassin could be the more appealing option.
Brand Reputation
Both products come from Thermalright, a brand with over 20 years of experience in the cooling market, known for its reliability and performance. The brand's longstanding reputation adds a level of trust for consumers. While both coolers are manufactured by the same company, the Peerless Assassin has gained more attention in the community for its performance and aesthetics, potentially making it a more popular choice among users.
Which should you buy?
Choosing between the Thermalright AXP-120-X67 Black ARGB Low Profile CPU Air Cooler and the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler ultimately depends on your specific needs. If you're looking for a compact solution with a slightly lower price of $32.59 and efficient cooling in a low-profile design, the AXP-120-X67 is a solid choice. However, if you prioritize higher airflow, better cooling performance with dual fans, and don't mind the larger footprint or slightly higher price of $32.90, the Peerless Assassin 120 SE could be the better option. Evaluate your case size, cooling needs, and budget to make the best decision for your build.
