Thermalright AXP90 X47 Full Low Profile CPU Cooler, vs Thermalrlght Peerless Assassin 120 SE CPU Air

Overview of the Products

In this comparison, we will look at the Thermalright AXP90 X47 Full Low Profile CPU Cooler and the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler. The AXP90 X47 is priced at $33.99, while the Peerless Assassin 120 SE is slightly cheaper at $32.90, making it about 17% less expensive. Both coolers cater to different needs, with the AXP90 X47 focusing on compactness and the Peerless Assassin 120 SE providing a more robust cooling solution.

Design and Build Quality

The Thermalright AXP90 X47 features an ultra-compact low-profile design, measuring only 47mm in height. This makes it an ideal choice for small builds and ITX cases. It incorporates a pure copper base for excellent heat conductivity, while the 92mm PWM fan ensures low noise levels at 22.4 dB(A). In contrast, the Thermalrlght Peerless Assassin 120 SE boasts a larger footprint, with dimensions of 125mm x 135mm x 155mm. It uses an aluminum heatsink cover and features six heat pipes, which enhance its structural integrity and cooling efficiency. Both coolers are well-built, but their designs cater to different user preferences and case sizes.

Cooling Performance

When it comes to cooling performance, the Thermalrlght Peerless Assassin 120 SE is designed to outperform the AXP90 X47. The Peerless Assassin features dual 120mm TL-C12C PWM fans that deliver a rated airflow of 66.17 CFM, significantly higher than the 42.58 CFM provided by the AXP90 X47’s single 92mm fan. Additionally, the Peerless Assassin utilizes AGHP technology to enhance heat exchange, making it a better choice for users with high-performance CPUs. However, for those with compact builds or limited space, the AXP90 X47 still offers decent performance for its size.

Noise Levels

In terms of noise levels, the AXP90 X47 operates quietly with a maximum noise level of 22.4 dB(A), making it suitable for users who prioritize a silent computing experience. The Thermalrlght Peerless Assassin 120 SE, while still relatively quiet, has a maximum noise level of 25.6 dB(A) due to its larger and more powerful fans. This difference may be negligible for some users, but those sensitive to noise might prefer the quieter operation of the AXP90 X47. Ultimately, the choice between these two coolers may come down to how much noise the user is willing to tolerate for increased cooling performance.

Installation and Compatibility

Both coolers offer compatibility with a range of CPU sockets, including Intel's LGA 1150, 1151, 1200, and 1700, as well as AMD’s AM4 and AM5. However, installation can vary. The AXP90 X47 features a more straightforward design that is easier to install in tight spaces, making it an excellent choice for users with compact cases. On the other hand, the Peerless Assassin 120 SE uses an SS2 installation system that requires careful attention to ensure proper contact with the CPU, alongside the original motherboard's backplate for AM4 and AM5 installations. Users should consider their comfort level with installation complexity when choosing between these two coolers.

Aesthetic Appeal

Aesthetically, the Thermalrlght Peerless Assassin 120 SE has an edge with its anodized brushed black top cover and dual-fan setup, which provides a more modern and appealing look. The AXP90 X47, while sleek in its low-profile design, lacks the visual impact of a dual-fan cooler. For users who value the appearance of their builds, the Peerless Assassin may be more appealing. However, the AXP90 X47's compactness can also be considered a design advantage for minimalist setups.

Price-to-Performance Ratio

The Thermalright AXP90 X47 is priced at $33.99, while the Thermalrlght Peerless Assassin 120 SE costs $32.90. Given their respective performances, the Peerless Assassin offers a better price-to-performance ratio due to its superior cooling capabilities and additional features. However, for those who require a compact cooler and are working within a smaller case, the AXP90 X47’s price may justify its performance for specific use cases. Ultimately, the choice will depend on whether the user prioritizes size or cooling performance.

Which should you buy?

Choosing between the Thermalright AXP90 X47 Full Low Profile CPU Cooler and the Thermalrlght Peerless Assassin 120 SE CPU Air Cooler largely depends on your specific needs. If you have a compact case and prioritize a low noise level, the AXP90 X47 is a solid choice. However, for users looking for superior cooling performance and aesthetics, the Peerless Assassin 120 SE is the better option despite its slightly larger size and higher noise level. Both coolers are excellent in their own right, making the decision highly dependent on the user's particular requirements.
