Overview of Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler
The Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler is a robust cooling solution priced at C$46.90. It features a dual tower design, which enhances its cooling performance, and is equipped with two PWM fans that provide colourful ARGB lighting effects. With a heat dissipation capability for CPUs with a Thermal Design Power (TDP) of 120 to 245W, this cooler is designed for serious gamers and overclockers looking for efficiency and aesthetics in their builds.
The cooler's dimensions stand at 125mm in length, 135mm in width, and 155mm in height, making it an imposing presence in a case. The use of six pure copper heat pipes along with a copper base ensures effective heat transfer and quiet operation, with noise levels reaching up to 25.6 dB(A). This product demonstrates Thermalright's commitment to high-performance cooling, backed by over 20 years of experience in the industry.
Overview of Noctua NF-A14 PWM
The Noctua NF-A14 PWM is an exceptional fan priced at C$34.95, tailored for versatile applications, including CPU coolers, water cooling radiators, and case ventilation. This premium fan features a 140mm square frame design, which is ideal for a wide range of setups, ensuring compatibility with various cases and cooling solutions.
Operating at a maximum speed of 1500 RPM, the NF-A14 PWM offers a quiet operation with a maximum noise level of 24.6 dB(A). Known for its durability and longevity, this fan has a Mean Time To Failure (MTTF) of over 150,000 hours, making it a reliable choice for long-term use. The fan’s advanced design includes Flow Acceleration Channels and an Advanced Acoustic Optimisation frame, ensuring superior cooling performance while minimizing noise.
Performance Comparison
In terms of performance, the Thermalright Peerless Assassin 120 SE ARGB is designed to handle a higher TDP than the Noctua NF-A14 PWM. With a TDP capability ranging from 120 to 245W, it is ideal for high-performance CPUs, especially those that are overclocked. Conversely, the NF-A14 PWM is a fan rather than a cooler, and while it excels at providing airflow, it does not have a specified TDP rating as it is meant to supplement cooling rather than replace a CPU cooler.
The two PWM fans included with the Peerless Assassin operate at a maximum speed of 1500 RPM, producing a substantial airflow of 66.17 CFM, which is particularly effective in dissipating heat from high-performance CPUs. The NF-A14 PWM, while quieter at 24.6 dB(A), provides a broad speed range of 300-1500 RPM, making it versatile but less powerful in terms of raw airflow compared to the Thermalright.
Noise Levels
When it comes to noise levels, the Noctua NF-A14 PWM has a slight edge over the Thermalright Peerless Assassin 120 SE ARGB. The NF-A14 PWM operates at a maximum of 24.6 dB(A), which is quieter than the Peerless Assassin's maximum of 25.6 dB(A). For users prioritizing silent operation, the NF-A14 PWM is a compelling choice, especially in quiet environments or builds where noise levels are crucial.
However, the difference in noise levels is marginal, and both products are designed to operate quietly under load. The slight increase in noise from the Thermalright may be acceptable for users seeking higher cooling performance, especially in gaming or intensive computing scenarios.
Aesthetics and Design
The Thermalright Peerless Assassin 120 SE ARGB stands out for its aesthetic appeal, featuring ARGB lighting that can enhance the look of any gaming rig. The colourful lighting effects allow for customization, making it a popular choice among gamers who want their setups to shine visually.
In contrast, the Noctua NF-A14 PWM opts for a more utilitarian design, prioritizing functionality over flashiness. While it doesn’t feature RGB lighting, its brown and beige colour scheme is iconic and has become synonymous with quality cooling solutions. Users looking for a visually striking cooler may prefer the Thermalright, while those focused on performance and reliability might favour the Noctua.
Installation and Compatibility
The installation process for both products is designed to be user-friendly, but they serve different purposes. The Thermalright Peerless Assassin supports a wide range of CPU sockets, including Intel (115X/1200/1700/17XX) and AMD (AM4), making it a versatile choice for various builds. It comes with the necessary mounting hardware to ensure compatibility across different platforms.
On the other hand, the Noctua NF-A14 PWM is a fan that can be easily integrated into various setups, whether as part of a cooling system or as case ventilation. It includes anti-vibration mounts, fan screws, and an extension cable, allowing for straightforward installation. While both products are compatible with a range of systems, the choice will depend on whether users need a CPU cooler or additional airflow.
Price Consideration
When comparing the price points, the Thermalright Peerless Assassin 120 SE ARGB is priced at C$46.90, while the Noctua NF-A14 PWM is slightly more affordable at C$34.95. The Thermalright commands a higher price due to its dual tower cooling design and added features like ARGB lighting, making it a premium option for users requiring substantial CPU cooling performance.
In contrast, the NF-A14 PWM, while cheaper, offers excellent value for a high-quality fan that is versatile and quiet. Users should consider what they are prioritizing—whether it’s the robust cooling capabilities of the Thermalright or the quiet performance and adaptability of the Noctua fan.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE ARGB and the Noctua NF-A14 PWM ultimately hinges on your specific cooling needs and aesthetic preferences. If you require a powerful CPU cooler capable of handling high TDP processors with the added flair of RGB lighting, the Thermalright is the better option. However, if you’re looking for a versatile, quiet fan that excels in a variety of applications, the Noctua NF-A14 PWM is a solid choice. Each product offers distinct advantages, and your decision should reflect your priorities in performance, noise levels, and design.
