Its six heat pipes employ GEN 5.0 Technology, ensuring that heat is dissipated effectively, and can handle a thermal design power (TDP) of up to 265 watts, making it suited for demanding tasks.

This cooler features dual thickened PWM fans, specifically the TL-C12C-X28 V2 model, which can spin at a maximum of 1850 RPM, providing an airflow of 88.19 CFM while keeping noise levels at or below 29.5 dB(A). The inclusion of metal fasteners for both Intel and AMD platforms enhances installation ease, ensuring compatibility with a range of CPU sockets.

Overview of Thermalright TL-S12RW X3 CPU Fan

The Thermalright TL-S12RW X3 CPU Fan is a budget-friendly cooling option priced at C$19.90, making it an attractive addition to any PC build. This fan measures 120mm x 120mm x 25mm and incorporates a unique design characterized by pure white aesthetics and slim ARGB lines. Notably, it operates at a maximum speed of 1500 RPM, producing an airflow of 47.6 CFM and a noise level of just 23.2 dB(A), making it one of the quieter options available.

Designed with an S-FDB V2 bearing, the TL-S12RW X3 fan significantly reduces vibrations and enhances longevity. Its counter-clockwise rotation helps optimize airflow, making it suitable not just as a case fan but also as a complement to CPU coolers. This versatility allows for improved cooling performance by efficiently removing heat from both the chassis and the CPU.

Design and Build Quality

In terms of design, the Thermalright Peerless Assassin 120 SE V2 CPU Cooler features a more substantial construction, with dimensions that support its advanced cooling capabilities. Its aluminum fins and pure copper base are designed for optimal heat dissipation, making it robust enough for high TDP CPUs. The dual fans add to its cooling efficiency, while the overall size ensures it fits well in most cases.

Conversely, the TL-S12RW X3 CPU Fan has a slim profile that makes it versatile for various applications. Its aesthetic appeal is enhanced by the pure white design and ARGB lines, which not only contribute to the visual aspects of a build but also make it an attractive choice for gamers and PC enthusiasts. While the S12RW X3 is not as large or powerful as the Peerless Assassin, its lightweight and compact design allow for easy integration into different setups.

Performance and Cooling Efficiency

When it comes to performance, the Thermalright Peerless Assassin 120 SE V2 excels with its ability to handle a TDP of up to 265 watts. This makes it ideal for overclocked and high-performance CPUs, as it effectively dissipates heat through its six heat pipes and dual fans. The maximum airflow of 88.19 CFM at a noise level of 29.5 dB(A) ensures that it maintains a balance between cooling efficiency and acoustics.

On the other hand, the Thermalright TL-S12RW X3, while not as powerful, still delivers commendable performance for its price. With a maximum airflow of 47.6 CFM and a lower noise output of 23.2 dB(A), it works well in less demanding setups or as a supplementary fan alongside a CPU cooler. Its ability to function effectively in both intake and exhaust configurations adds to its versatility in managing system temperatures.

Compatibility and Installation

The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is designed for a wide range of CPUs, supporting Intel sockets LGA 1851, 1700, 1200, and 115X, as well as AMD AM4 and AM5.
