Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler vs Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler

Introduction to CPU Coolers

When choosing a CPU cooler, two compelling options from Thermalright stand out: the Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler. Both coolers offer unique features tailored to different needs, making them suitable for a variety of builds. The AXP90-X47 is priced at £41.90, while the Peerless Assassin 120 SE is more budget-friendly at £28.79.

Design and Size

The design and size of a cooler are pivotal in determining its compatibility and performance. The Thermalright AXP90-X47 features a compact size of 94.5×95×47mm, making it an excellent choice for small form factor builds such as ITX and HTPC systems. In contrast, the Thermalright Peerless Assassin 120 SE is larger, measuring 125mm in length, 135mm in width, and 155mm in height. While the larger size of the Peerless Assassin allows for better cooling potential with its dual fans, it may pose compatibility issues in tighter spaces.

Cooling Performance

Cooling performance is critical for maintaining optimal CPU temperatures. The AXP90-X47 utilises a 92mm PWM fan that achieves a maximum airflow of 42.58 CFM and operates at a noise level of 22.4 dB(A). On the other hand, the Peerless Assassin 120 SE employs two 120mm PWM fans, delivering a maximum airflow of 66.17 CFM. This higher airflow capacity, combined with a noise level of up to 25.6 dB(A), suggests that while the Peerless Assassin may be louder, it offers superior cooling performance, especially for overclocked CPUs.

Installation and Compatibility

Ease of installation and compatibility with various CPU sockets is essential for any cooler. The AXP90-X47 supports a wide range of Intel and AMD sockets, including Intel LGA 1700 and AMD AM4/AM5, making it versatile for different builds. It is designed to prevent memory limitations due to its low profile. In comparison, the Peerless Assassin also supports multiple sockets, including Intel 115X and AMD AM4/AM5, and comes with metal fasteners for easy installation. However, its larger size may limit compatibility with some compact cases.

Noise Levels

Noise levels play a significant role in user experience, particularly for those who prefer a quieter environment. The AXP90-X47 operates at a maximum noise level of 22.4 dB(A), making it a silent performer in low to moderate workloads. The Peerless Assassin 120 SE, while still relatively quiet, can reach noise levels of up to 25.6 dB(A) under load, which may be noticeable in quieter settings. Therefore, if silence is a priority, the AXP90-X47 may be the more suitable choice.

Aesthetics and Features

Aesthetics can enhance the overall look of your build, and here the Peerless Assassin 120 SE has a distinct advantage. It features ARGB lighting, adding a vibrant touch to any system. The AXP90-X47, while functional, does not offer any lighting features, making it less visually appealing for users who prioritise aesthetics. Both coolers boast the AGHP technique, which improves cooling performance by solving the inverse gravity effect, but the visual flair of the Peerless Assassin may attract gamers and modders more.

Brand Reputation and Reliability

Thermalright is a well-respected brand in the cooling industry, boasting over 20 years of experience. Both products reflect the brand's commitment to quality and performance. The popularity of Thermalright in both domestic and international markets enhances consumer confidence in both the AXP90-X47 and the Peerless Assassin 120 SE. Reliability is likely to be consistent across both models, but the Peerless Assassin's dual fan setup may provide an edge in longevity and cooling efficiency.

Which should you buy?

Choosing between the Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific needs. If you're building a compact system and prioritising low noise levels, the AXP90-X47 at £41.90 is an excellent choice. However, if you desire superior cooling performance, aesthetic appeal, and are willing to trade off some noise for those benefits, the Peerless Assassin 120 SE at £28.79 offers great value. Assess your build's requirements and choose accordingly for the best performance and user experience.
