ARCTIC P12 PWM PST A-RGB - PC FanThermalright Peerless Assassin 120 SE ARGB CPU Air Cooler

Overview of the ARCTIC P12 PWM PST A-RGB

The ARCTIC P12 PWM PST A-RGB is a high-performance PC fan designed for effective cooling and aesthetic appeal. Priced at £16.49, it features 12 A-RGB LEDs that provide vibrant illumination, enhancing the look of any build. With a fan speed range of 200 to 2000 RPM, it ensures optimal airflow and static pressure, making it suitable for various applications, including heat sinks and radiators.

This fan integrates a 4-pin connector for PWM control, allowing for efficient speed regulation and minimal noise during operation. Its impressive airflow rating of 48.80 CFM and static pressure of 1.85 mmH₂O guarantee effective cooling performance. Given its competitive price point and features, the ARCTIC P12 is an appealing choice for users looking to enhance their cooling capabilities without breaking the bank.

Overview of the Thermalright Peerless Assassin 120 SE ARGB

The Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler stands out with its dual fan design and advanced cooling technology, retailing at £28.79. This cooler features two PWM fans, which deliver a maximum airflow of 66.17 CFM, ensuring efficient heat dissipation from the CPU. The ARGB lighting effects add a striking visual element, catering to gamers and PC enthusiasts alike.

Utilising six heat pipes and a full electroplating reflow welding process, the cooler aims to maximise thermal performance. It operates at a fan speed of approximately 1500 RPM, which keeps noise levels at a manageable ≤25.6 dB(A). With broad compatibility spanning Intel and AMD sockets, it’s designed for seamless integration into a variety of systems, making it a solid option for those seeking robust CPU cooling solutions.

Design and Aesthetics

In terms of design, the ARCTIC P12 PWM PST A-RGB is sleek and modern, featuring a transparent rotor that complements its A-RGB lighting. This design not only enhances the visual appeal but also aids in achieving even illumination. The integrated Y-splitter facilitates easy installation and allows for expanded cooling setups, making it user-friendly.

Conversely, the Thermalright Peerless Assassin 120 SE ARGB boasts a more substantial build with its dual tower design. This structure not only supports greater cooling efficiency but also provides more room for airflow around the RAM, which can be crucial in tight builds. The ARGB effects on the cooler contribute to a more dynamic aesthetic, appealing to users who prioritise visual flair in their setups. Both products offer impressive aesthetics, but their designs cater to slightly different user preferences—one focusing on simplicity and another on a more robust presence.

Cooling Performance

The cooling performance of the ARCTIC P12 PWM PST A-RGB is commendable, with a static pressure rating of 1.85 mmH₂O and a maximum airflow of 48.80 CFM. This makes it particularly efficient for use on heat sinks and radiators, ensuring that components remain cool even under heavy loads. The ability to adjust the fan speed from 200 to 2000 RPM via PWM control allows for tailored cooling based on system demands, achieving a balance between noise and performance.

On the other hand, the Thermalright Peerless Assassin 120 SE excels with its dual fans and higher maximum airflow rating of 66.17 CFM. The six heat pipes significantly enhance heat transfer, ideally situating it for high-performance CPUs. Operating at a relatively quiet ≤25.6 dB(A), it offers a strong cooling solution that doesn't compromise on noise levels. In direct comparison, while the ARCTIC fan is excellent for general use, the Thermalright cooler is designed specifically for demanding applications, making it a more robust option for gamers and overclockers.

Installation and Compatibility

The installation process for the ARCTIC P12 PWM PST A-RGB is simplified by its integrated Y-splitter for fan and A-RGB cables. This feature is particularly beneficial for users looking to expand their cooling systems with multiple fans. The 4-pin connector also ensures compatibility with a broad range of motherboards, streamlining the installation process.

The Thermalright Peerless Assassin 120 SE ARGB is designed with versatility in mind, supporting various CPU socket types including Intel’s 115X/1200/1700/17XX and AMD’s AM4/AM5. This wide compatibility is bolstered by the inclusion of necessary mounting hardware, making it accessible for a diverse range of builds. However, the dual tower design may require more space within the case compared to the ARCTIC fan. Overall, both products offer straightforward installation, though the Peerless Assassin is better suited for users with specific high-performance cooling needs.

Noise Levels

Noise performance is an essential consideration for PC builders, particularly in quiet environments. The ARCTIC P12 PWM PST A-RGB operates at a noise level of 0.3 Sone, which is relatively quiet, especially when running at lower RPMs. This feature allows users to enjoy a cooler system without the distraction of excessive noise, making it ideal for builds where silence is a priority.

In comparison, the Thermalright Peerless Assassin 120 SE maintains a maximum noise level of ≤25.6 dB(A), which is still relatively quiet, especially given its higher airflow. While both cooling solutions prioritise quiet operation, the ARCTIC fan offers a slight edge in terms of silence during low-speed operation. However, users should consider that the Peerless Assassin's noise levels are still acceptable for a dual-fan cooler delivering substantial performance.

Price Considerations

When comparing prices, the ARCTIC P12 PWM PST A-RGB is priced at £16.49, making it a budget-friendly option for users seeking effective cooling without spending excessively. Its features, including A-RGB lighting and high static pressure, provide excellent value for money.

The Thermalright Peerless Assassin 120 SE ARGB, priced at £28.79, is positioned as a higher-end option due to its advanced cooling capabilities and dual-fan design. While it requires a larger investment, it offers enhanced performance suitable for more demanding applications. Users must weigh their cooling needs against their budget, as the difference in price reflects a significant increase in cooling performance and compatibility options.

Which should you buy?

Choosing between the ARCTIC P12 PWM PST A-RGB and the Thermalright Peerless Assassin 120 SE ARGB largely depends on your specific needs and preferences. If you’re looking for a cost-effective, visually appealing fan that excels in standard cooling applications, the ARCTIC P12 is an excellent choice. However, for users seeking superior cooling performance, especially in high-demand scenarios, the Thermalright Peerless Assassin 120 SE offers advanced features and robust capabilities, albeit at a higher price point. Ultimately, your decision should align with your cooling requirements, build aesthetics, and budget constraints.
