Dimension comparison
Design and Aesthetics
The Delta A40 ARGB CPU Cooler features a modern design with circular elements and a mirror-like finish, while the Thermalright TL-S12RW X3 CPU Fan boasts a pure white design with slim round ARGB accents. Both products prioritise aesthetic appeal, but they cater to different visual preferences. The Delta A40’s unique circular design is complemented by customizable ARGB lighting effects, allowing for a highly personalized setup. In contrast, the Thermalright TL-S12RW’s simplistic elegance with soft silicone feet aims to enhance its value while effectively reducing noise.
Cooling Performance
In terms of cooling capabilities, the Delta A40 ARGB can handle up to 220W power dissipation, making it a robust choice for high-performance CPUs during gaming or creative tasks. Its airflow reaches 73 CFM with a noise level of ≤29 dB(A). Meanwhile, the Thermalright TL-S12RW X3 offers a maximum airflow of 47.6 CFM at a quieter noise level of ≤23.2 dBA. While the Delta A40 excels in sheer cooling power, the Thermalright model may provide a quieter operation, making it suitable for users prioritizing noise levels alongside performance.
Fan Specifications
The Delta A40 features a 120mm PWM silent cooling fan that operates between 500 to 2000 ±10% RPM, designed for high airflow and pressure efficiency. This allows it to maintain effective cooling under varying loads. Conversely, the Thermalright TL-S12RW X3 operates at a fixed speed of 1500 RPM, offering consistent performance but limited variability. While both fans are 120mm in size, the Delta A40’s adjustable speed provides a significant edge in adapting to different cooling needs based on system demands.
Noise Levels
When it comes to operational noise, the Thermalright TL-S12RW X3 shines with its maximum noise level of ≤23.2 dBA, making it one of the quieter options available. On the other hand, the Delta A40 operates at ≤29 dB(A), which is slightly noisier but still within an acceptable range for most users. If silence is a critical factor for your build, the Thermalright might be the better choice, but the Delta A40 compensates with superior cooling capabilities, especially under heavy loads.
Installation and Compatibility
Both the Delta A40 and the Thermalright TL-S12RW X3 are designed for easy installation. The Delta A40 includes all-metal mounting hardware compatible with a variety of Intel and AMD platforms, including AM4 and LGA 1700, while the Thermalright fan can be used as a case fan or in conjunction with a CPU cooler, enhancing its versatility. This compatibility makes both products suitable for a wide range of builds, ensuring that users can easily integrate them into their systems without extensive hassle.
Lifespan and Durability
The Thermalright TL-S12RW X3 utilises an S-FDB V2 bearing, which is designed to reduce vibrations and extend the fan's lifespan, contributing to a longer trouble-free operation. This can be particularly appealing for users seeking reliability over extended periods of use. The Delta A40, while not specifying a bearing type, emphasises durability in its design through features like folded edges and clipped FIN technology, which enhance heat dissipation and reduce wind resistance, but it does not explicitly mention longevity aspects.
Pricing
The pricing of both products is quite competitive, with the Delta A40 ARGB available for C$19.29 and the Thermalright TL-S12RW X3 slightly higher at C$19.90. The price difference of only C$0.61 may not be significant to many buyers, but it does reflect the different features and cooling capabilities offered by each product. The Delta A40 may provide better overall performance for demanding applications, while the Thermalright may appeal to those looking for a more budget-friendly option with lower noise levels.
Which should you buy?
Choosing between the Delta A40 ARGB CPU Cooler and the Thermalright TL-S12RW X3 CPU Fan ultimately depends on your specific needs. If you require top-notch cooling performance for high-load situations and value customizable aesthetics, the Delta A40 is an excellent choice. However, if you prioritise a quieter operation and versatile use as both a case and CPU cooler, the Thermalright TL-S12RW X3 may be the better option for you. Assessing your cooling requirements, noise tolerance, and aesthetic preferences will guide you to the right decision for your build.
