Introduction
In the world of cooling solutions, two products stand out for their unique features: the ARCTIC P12 Slim PWM PST and the Thermalright AXP90-X47 Full Low Profile ITX CPU Air Cooler. Both products cater to different needs, with the ARCTIC fan focusing on efficient airflow in compact spaces, while the Thermalright cooler promises robust CPU cooling for small form factor systems. This article will delve into various aspects of each product, helping you decide which option best suits your needs.
Design and Dimensions
The design and dimensions of a cooling solution are pivotal when considering compatibility with your system. The ARCTIC P12 Slim PWM PST boasts an installation height of just 15 mm, making it an excellent choice for small form factor cases where space is at a premium. On the other hand, the Thermalright AXP90-X47 measures 94.5×95×47 mm in size. While it is taller at 47 mm, it still qualifies as a low-profile cooler, making it suitable for HTPC and ITX builds without memory clearance issues.
Cooling Performance
When it comes to cooling performance, both products offer impressive specifications. The ARCTIC P12 Slim operates efficiently at speeds ranging from 200 to 2100 RPM and provides a maximum airflow of 34.51 cfm. This allows it to maintain a low noise level of only 0.3 Sone while ensuring adequate cooling even in high-resistance environments. Conversely, the Thermalright AXP90-X47 features a matched fan that can reach speeds up to 2700 RPM and delivers an air volume of 42.58 CFM at a noise level of 22.4 dB(A). This indicates that while both units are designed for effective cooling, the Thermalright cooler provides a higher airflow output, albeit at a potentially noisier operation.
Static Pressure
Static pressure is another critical factor that impacts cooling efficiency, especially in constrained environments. The ARCTIC P12 Slim boasts a static pressure of 1.33 mmH₂O, making it well-suited for applications such as heat sinks and radiators where air resistance can be a concern. Similarly, the Thermalright AXP90-X47 also claims a maximum static pressure of 1.33 mmH₂O, indicating that both products are designed to perform effectively under similar conditions. This parity in static pressure suggests that either cooler can handle challenging airflow scenarios effectively.
Noise Levels
Noise levels are a significant consideration for users looking to maintain a quiet computing environment. The ARCTIC P12 Slim operates at a minimal noise level of just 0.3 Sone, making it an ideal choice for those who prioritise silence in their builds. In stark contrast, the Thermalright AXP90-X47 has a noise level of 22.4 dB(A), which, while not excessively loud, is considerably higher than that of the ARCTIC fan. This difference in noise output may sway users who are sensitive to sound towards the ARCTIC P12 Slim for quieter operation.
Installation and Compatibility
Both products are designed for ease of installation and compatibility with various systems. The ARCTIC P12 Slim, with its low profile, is specifically tailored for small form factor cases, ensuring compatibility with installations where standard 25 mm fans would not fit. Meanwhile, the Thermalright AXP90-X47 is compatible with a range of Intel and AMD sockets, including LGA 1700 and AM5, ensuring broad compatibility across modern systems. Its design also incorporates a copper radiator and advanced heat pipe technology, which enhances heat transfer efficiency.
Price Comparison
Price can often be a deciding factor when choosing between cooling solutions. The ARCTIC P12 Slim PWM PST is priced at £18.90 for a three-pack, offering exceptional value for users needing multiple fans. In contrast, the Thermalright AXP90-X47 is priced at £41.90, reflecting its more complex design and higher performance capabilities. While the ARCTIC fan offers a cost-effective solution for cooling, the Thermalright cooler may justify its higher price with its advanced features and cooling capacity, making it a worthwhile investment for performance-focused users.
User Applications
The intended usage scenarios for each product can significantly influence your decision. The ARCTIC P12 Slim is designed primarily as a fan, making it versatile for various cooling applications, including case cooling and as an addition to CPU coolers. Its slim profile suits users with compact builds, ensuring effective airflow without occupying too much space. In contrast, the Thermalright AXP90-X47 is a dedicated CPU cooler, optimised for efficient heat dissipation in small systems. Ideal for users building compact yet powerful machines, it utilises advanced cooling technologies to ensure optimal CPU performance.
Which should you buy?
Choosing between the ARCTIC P12 Slim PWM PST and the Thermalright AXP90-X47 comes down to your specific needs. If you require a budget-friendly, low-profile fan that excels in quiet operation and versatility, the ARCTIC P12 Slim is an excellent choice. However, if you prioritise high-performance cooling for a compact CPU setup and are willing to invest more, the Thermalright AXP90-X47 offers superior airflow and cooling capabilities. Ultimately, your choice should align with your cooling requirements, system compatibility, and budget considerations.
