Overview of the Products

The Thermalright TL-C12CW-S X3 CPU Fan and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler serve distinct purposes within the realm of CPU cooling. The TL-C12CW-S X3 is a 120mm case fan designed primarily for case ventilation and additional cooling support, priced at C$17.99. In contrast, the Peerless Assassin 120 SE V2 is a complete CPU cooler, retailing at C$54.90, which incorporates advanced cooling technology suitable for high-performance CPUs.

Design and Build Quality

The design of both products reflects Thermalright's commitment to quality. The TL-C12CW-S X3 features a sleek white ARGB design that enhances aesthetic appeal with up to 17 lighting modes, making it suitable for modern builds. It utilises quality S-FDB bearings to minimise noise and extend its lifespan. The Peerless Assassin, on the other hand, is larger with dimensions of 125mm x 135mm x 155mm, and it utilises aluminum fins on a copper base. This combination aids in efficient heat dissipation, making it ideal for demanding applications while ensuring durability.

Cooling Performance

Cooling performance is one of the most critical factors when comparing these two products. The TL-C12CW-S X3 offers a maximum speed of 1550 RPM with an airflow of 66.17 CFM, delivering adequate cooling for case ventilation. Its noise level is capped at 25.6 dBA, ensuring quiet operation. Conversely, the Peerless Assassin boasts a higher fan speed of 1850 RPM and an impressive airflow of 88.19 CFM. This allows it to handle TDPs of up to 265W, making it suitable for overclocked CPUs, a significant advantage in high-performance scenarios.

Noise Levels

When it comes to noise levels, both products maintain relatively quiet operations, but the TL-C12CW-S X3 has a slight edge. With a noise level of ≤ 25.6 dBA, it operates quietly, making it an excellent choice for users prioritising a silent build. The Peerless Assassin, while still relatively quiet at ≤ 29.5 dBA, emits slightly more noise due to its higher RPM and airflow capabilities. Users who are sensitive to noise may prefer the TL-C12CW-S X3, particularly in environments where silence is critical.

Compatibility

Compatibility is crucial when selecting cooling solutions. The TL-C12CW-S X3 can be seamlessly integrated into various builds as a case fan, enhancing airflow and overall cooling. The Peerless Assassin offers broader compatibility as a CPU cooler, supporting Intel sockets LGA 1851, 1700, 1200, and 115X, alongside AMD AM4 and AM5 sockets. This versatility makes it a fitting choice for users building or upgrading their systems with different CPU architectures.

Installation Process

Both products are designed for relatively straightforward installation. The TL-C12CW-S X3 connects via a 4-pin PWM fan cable, allowing for automatic speed control based on motherboard temperature. The Peerless Assassin features metal fasteners for Intel and AMD platforms, ensuring secure installation. The inclusion of mounting plates simplifies the process, allowing users of varying skill levels to install the cooler without extensive experience.

Aesthetic Appeal

Aesthetic appeal can be a significant factor for many builders. The TL-C12CW-S X3 stands out with its white ARGB lighting, making it a visually striking component in any case. It can synchronise with other ARGB components, enhancing the overall build’s visual impact. In contrast, the Peerless Assassin, while not equipped with RGB lighting, features a sleek and professional design that will appeal to users who prefer a more understated look without sacrificing performance.

Which should you buy?

Choosing between the Thermalright TL-C12CW-S X3 CPU Fan and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler depends largely on your specific needs. If you're looking for an efficient case fan that combines aesthetics with decent cooling performance, the TL-C12CW-S X3 at C$17.99 is an excellent choice. However, for users seeking robust CPU cooling capable of handling high-performance processors, the Peerless Assassin at C$54.90 offers superior airflow and cooling capabilities. Ultimately, your decision should be guided by whether you need a supplemental case fan or a full-fledged CPU cooler.
