Noctua NF-A4x20 PWM vs Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler

Overview of the Products

The Noctua NF-A4x20 PWM and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler are two distinct cooling solutions catering to different needs. The Noctua fan, priced at £18.40, is designed primarily for compact spaces, while the Thermalright cooler, retailing at £28.79, targets users seeking robust CPU cooling performance.

Design and Build Quality

The design of the Noctua NF-A4x20 PWM is focused on efficiency and quiet operation, featuring a premium quiet fan measuring 40x40x20 mm. It is specifically crafted for 1U servers and similar devices. In contrast, the Thermalright Peerless Assassin 120 SE ARGB boasts a larger design, measuring 125x135x155 mm, and includes dual PWM fans. The aesthetic appeal is enhanced by its colourful ARGB lighting, making it a suitable choice for those who value visual flair in their builds.

Cooling Performance

When it comes to cooling performance, the Noctua NF-A4x20 PWM can reach a maximum speed of 5000 RPM, producing a noise level of just 14.9 dB(A). This makes it one of the quietest options available, ideal for noise-sensitive environments. On the other hand, the Thermalright Peerless Assassin 120 SE achieves a maximum fan speed of 1500 RPM with a higher noise level of up to 25.6 dB(A). While both fans are efficient, the Noctua fan excels in silent operation, whereas the Thermalright cooler is designed for more substantial airflow.

Compatibility and Installation

The Noctua NF-A4x20 PWM is versatile in its compatibility, making it suitable for various applications, including routers and NAS devices. It comes with an anti-vibration mount and an OmniJoin adaptor set, ensuring easy installation. The Thermalright Peerless Assassin 120 SE is also compatible with a range of sockets, including Intel and AMD platforms. It includes metal fasteners for secure installation, but its larger size may require more careful planning during setup compared to the compact Noctua fan.

Noise Levels

Noise levels are critical when considering cooling solutions. The Noctua NF-A4x20 PWM stands out with a maximum noise level of only 14.9 dB(A), which is almost inaudible, making it perfect for quiet office environments or home theatres. In contrast, the Thermalright Peerless Assassin 120 SE operates at a maximum noise level of 25.6 dB(A). While this is still relatively quiet, it may be noticeable in silent settings. The Noctua fan's design prioritises silent cooling, making it a favourite among users who are sensitive to noise.

Price Comparison

Price-wise, the Noctua NF-A4x20 PWM is more affordable at £18.40 compared to the Thermalright Peerless Assassin 120 SE, which costs £28.79. This represents a price difference of £10.39, making the Noctua fan a more budget-friendly option for those who do not require extensive CPU cooling capabilities. However, if users are looking for a cooling solution that can handle higher thermal loads, the investment in the Thermalright product may justify its higher price.

Target Audience

The Noctua NF-A4x20 PWM is designed for users needing a compact and quiet fan solution, particularly in tight spaces like servers or NAS devices. Its focus on low noise and compact size makes it ideal for professionals in office environments. Conversely, the Thermalright Peerless Assassin 120 SE is tailored to gamers and PC builders looking for an effective cooling solution for high-performance CPUs. Its dual fan setup and aesthetic features cater to users who prioritise both performance and style in their builds.

Which should you buy?

Choosing between the Noctua NF-A4x20 PWM and the Thermalright Peerless Assassin 120 SE boils down to your specific needs. If you require a compact, ultra-quiet solution for smaller devices, the Noctua fan at £18.40 is the optimal choice. However, for those seeking superior cooling performance for high-end CPUs, the Thermalright cooler, despite its higher price of £28.79, offers significant benefits with its dual fans and effective heat dissipation. Each product has its strengths, making your decision dependent on the intended application and personal preferences.
