Overview of the Noctua NF-A8 PWM and Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler

The Noctua NF-A8 PWM and Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler are two distinct cooling solutions catering to different needs and preferences. The Noctua NF-A8 PWM, priced at £24.59, is a compact 80mm fan aimed at quiet operation, while the Thermalright Peerless Assassin 120 SE, at £28.79, is a larger air cooler designed for more demanding CPU cooling. While both products have their merits, they serve different purposes in the realm of cooling technology.

Design and Build Quality

The design and build quality of a cooling solution can significantly impact its performance and user experience. The Noctua NF-A8 PWM features a premium construction that is especially suited for compact PC cases. Its 80x80x25 mm size makes it ideal for small form factor builds, providing efficient airflow without taking up excessive space. On the other hand, the Thermalright Peerless Assassin 120 SE boasts a larger footprint with dimensions of 125x135x155 mm. This design accommodates dual fans and advanced heat pipe technology, ensuring superior cooling performance. Both products exhibit high-quality build standards, but the choice hinges on the user’s case size and cooling requirements.

Noise Levels

Noise is a critical consideration for many PC builders, and both fans excel in this area but in different capacities. The Noctua NF-A8 PWM achieves a maximum noise level of just 17.7 dB(A), making it one of the quietest fans available. This low noise output is particularly advantageous for users seeking a silent computing environment. In contrast, the Thermalright Peerless Assassin 120 SE has a higher noise level, reaching up to 25.6 dB(A). While this is still acceptable for most users, it does indicate that the Noctua fan is the preferable choice for those prioritising quiet operation.

Cooling Performance

When it comes to cooling performance, size often matters. The Thermalright Peerless Assassin 120 SE is equipped with two PWM fans that can achieve an airflow of 66.17 CFM, facilitating excellent heat dissipation. Its advanced AGHP technique and six heat pipes ensure that it maintains optimal CPU temperatures even under heavy loads. In contrast, the Noctua NF-A8 PWM's airflow is tailored more for smaller applications, which means it may not cool as effectively as the larger Thermalright model in high-performance scenarios. Therefore, for users with high-performance CPUs, the Thermalright cooler stands out for its superior cooling capabilities.

Compatibility

Compatibility of a cooler with different CPU sockets is essential for seamless integration into various builds. The Noctua NF-A8 PWM is a versatile fan that can serve as an intake or exhaust in compact cases, making it suitable for a wide range of setups. However, it lacks the dedicated CPU mounting that the Thermalright Peerless Assassin 120 SE offers. The Thermalright cooler is compatible with a variety of Intel and AMD sockets, including Intel 115X, 1200, 1700, and AMD AM4, AM5. This broad compatibility makes it a more flexible option for users building or upgrading their systems.

Installation Process

The ease of installation can greatly influence a user’s experience with a cooling product. The Noctua NF-A8 PWM comes with anti-vibration mounts, fan screws, and other accessories, which simplify the installation process. However, due to its compact size, the installation may not be as complex as that of larger coolers. In contrast, the Thermalright Peerless Assassin 120 SE, with its dual tower design, may require a more careful installation approach, but it includes metal fasteners for better mounting stability. Users should weigh the installation complexity against their comfort level with component assembly.

Aesthetics

Aesthetics can play a crucial role in a PC build, especially for those who prefer a visually appealing setup. The Noctua NF-A8 PWM has a classic brown and beige design that may not suit everyone’s taste, although it is widely regarded for its understated elegance. In contrast, the Thermalright Peerless Assassin 120 SE features colourful ARGB lighting, adding a modern touch that can enhance the visual appeal of a gaming rig. Users looking for a cooler that adds a vibrant look to their build may prefer the Thermalright model.

Price Comparison

Price is always a significant factor when choosing between products. The Noctua NF-A8 PWM is priced at £24.59, making it a cost-effective choice for users seeking a reliable and quiet fan. The Thermalright Peerless Assassin 120 SE, at £28.79, is slightly more expensive but offers a more comprehensive cooling solution with its dual fans and advanced features. While both options are competitively priced, potential buyers should consider their specific needs to determine if the additional cost of the Thermalright cooler justifies its enhanced performance.

Which should you buy?

Deciding between the Noctua NF-A8 PWM and the Thermalright Peerless Assassin 120 SE ultimately hinges on your cooling requirements and system configuration. If you are building a compact PC and prioritise quiet operation, the Noctua NF-A8 PWM is an excellent choice, with its low noise levels and compact size. However, if you require stronger cooling performance for a high-end CPU and are willing to invest a bit more, the Thermalright Peerless Assassin 120 SE, with its dual fans and advanced cooling technology, is the better option. Both products have their strengths, so consider factors like case size, noise tolerance, and aesthetic preference to make the best choice for your build.
