Dimension comparison
Price Comparison
When considering affordability, the ARCTIC P12 Slim PWM PST is significantly cheaper at £5.87 compared to the Thermalright TL-M12QR-S X3, which is priced at £20.59. This price difference of £14.72 highlights the ARCTIC fan as a more budget-friendly option for those seeking effective cooling solutions without breaking the bank. While the Thermalright fan offers advanced features, the ARCTIC model allows users to save substantially while still receiving solid performance.
Cooling Performance
The ARCTIC P12 Slim PWM PST excels in static pressure with a performance rating of 1.33 mmH₂O, making it ideal for scenarios with increased air resistance, such as on heat sinks and radiators. In contrast, the Thermalright TL-M12QR-S X3 offers a maximum airflow of 47.6 CFM and a slightly lower static pressure rating of 1.31 mmH₂O. This means that while both fans provide good cooling capabilities, the ARCTIC model is specifically optimised for high-resistance cooling tasks, giving it a slight edge in performance under challenging conditions.
Noise Levels
The ARCTIC P12 Slim PWM PST operates at a noise level of just 0.3 Sone, making it an exceptionally quiet fan, especially given its capability to reach speeds of up to 2100 RPM. The Thermalright TL-M12QR-S X3, while also designed for quieter operation, has a noise level of up to 23.2 decibels at its maximum speed of 1500 RPM. This means that the ARCTIC fan operates at a significantly lower noise level, making it better suited for users prioritising silence in their builds.
Design and Aesthetics
In terms of design, the Thermalright TL-M12QR-S X3 stands out with its ARGB infinite mirror effect, which provides a visually striking aesthetic with its segmented LED light strip and multiple layers of lighting. The ARCTIC P12 Slim PWM PST, on the other hand, has a more utilitarian design focused on functionality rather than visual appeal. While both fans are effective in their cooling capabilities, the Thermalright fan is likely to attract users who value RGB lighting and design flair in their PC builds.
Installation and Compatibility
The ARCTIC P12 Slim PWM PST is designed with a low installation height of only 15 mm, making it particularly suitable for small form factor cases where space is limited. This feature allows for versatile installation options, even in tighter enclosures. The Thermalright TL-M12QR-S X3 measures 124x120x25 mm, which may pose compatibility issues in very compact cases. Individuals with space constraints or smaller cases will likely find the ARCTIC fan more accommodating for their needs.
Fan Speed Control
The ARCTIC P12 Slim PWM PST features a 4-pin connector that allows for PWM control, enabling its speed to range from 200 to 2100 RPM. This flexibility helps maintain optimal cooling performance while minimising noise levels. The Thermalright TL-M12QR-S X3 also utilises a 4-pin PWM connection but has a fixed speed of 1500 RPM, which limits its adaptability to varying cooling needs. The ability to control the fan speed dynamically gives the ARCTIC fan an advantage in maintaining efficiency under different operating conditions.
Build Quality and Durability
Both fans are designed with longevity in mind, but they approach it differently. The ARCTIC P12 Slim PWM PST benefits from upgraded engine technology and a newly developed fan design aimed at enhancing performance and durability. The Thermalright TL-M12QR-S X3 incorporates a noise-reducing 7-blade design and soft silicone corner pads for vibration dampening, contributing to its silent operation. While both products are built to last, the ARCTIC fan’s focus on performance enhancements suggests a potentially longer lifespan under high-stress conditions.
Which should you buy?
Ultimately, the choice between the ARCTIC P12 Slim PWM PST and the Thermalright TL-M12QR-S X3 boils down to individual requirements. If you prioritise budget, low noise levels, and high static pressure for efficient cooling, the ARCTIC fan is the clear winner at £5.87. However, if aesthetic appeal and ARGB lighting are significant factors for your build, you may find the Thermalright TL-M12QR-S X3’s features worth the higher price of £20.59.
