Thermalright Peerless Assassin 120 SE CPU Cooler vs Thermalright TL-S12W X3 CPU Fan 120mm Case Cooler Fan

Design and Build Quality

The Thermalright Peerless Assassin 120 SE CPU Cooler is a comprehensive cooling solution featuring a dual tower heatsink made from aluminum and copper, whereas the Thermalright TL-S12W X3 CPU Fan 120mm Case Cooler Fan is a single 120mm fan designed for versatile cooling applications. The Peerless Assassin 120 SE measures 125mm in length, 135mm in width, and 155mm in height, offering a substantial presence optimized for extensive heat dissipation with its six 6mm copper heat pipes and dual high airflow fans. In contrast, the TL-S12W X3 is a 120x120x25mm fan made with insulation-grade PBT+PC material, including soft silicone feet for noise damping. While the Peerless Assassin integrates both heatsink and fans as a complete CPU cooler, the TL-S12W X3 is strictly a fan unit meant for case or supplemental CPU cooling.

Cooling Performance

The Peerless Assassin 120 SE CPU Cooler provides advanced cooling performance through its six copper heat pipes and two 120mm fans rated at a maximum airflow of 66.17 CFM each. Its dual tower configuration and AGHP technology assist in rapid heat exchange, addressing orientation effects for optimal heat dissipation. The fans operate at up to 1550 RPM with a noise level capped at 25.6 dB(A). On the other hand, the TL-S12W X3 fans each deliver up to 47.6 CFM airflow at a speed of 1500 RPM and a lower noise level of 23.2 dB(A). Although quieter, the TL-S12W X3 fans offer less airflow compared to the Peerless Assassin fans, reflecting their role as case or auxiliary fans rather than standalone CPU coolers. Overall, the Peerless Assassin is engineered for superior CPU heat management with higher airflow and heat pipe technology.

Compatibility and Installation

Compatibility-wise, the Peerless Assassin 120 SE supports a wide range of Intel sockets including LGA1150 through LGA1851 and AMD AM4/AM5 platforms, with the caveat that AM4 and AM5 installations require the motherboard’s original backplate, which is not included. Its SS2 install system and metal pressure plate improve contact with the CPU for better heat exchange. The TL-S12W X3 fan is broadly compatible as a case fan or CPU cooler fan replacement, connecting via a standard 4-pin PWM interface with automatic speed control based on motherboard temperature. It includes a 55cm cable for flexible installation but does not require specific mounting hardware beyond standard screws. The Peerless Assassin’s mounting complexity is higher due to its heatsink and backplate requirements, whereas the TL-S12W X3 is straightforward to install in most PC cases or on existing coolers.

Noise Levels and Fan Operation

The Thermalright TL-S12W X3 excels in quieter operation, with noise levels rated at or below 23.2 dB(A) at maximum speed, benefiting from soft silicone feet that reduce vibration and noise transmission. The Peerless Assassin 120 SE fans have a slightly higher noise ceiling at 25.6 dB(A) but compensate with greater airflow and cooling capacity. Both models feature 4-pin PWM connectors for automatic speed regulation based on temperature, allowing dynamic balancing of cooling performance and noise. Users prioritizing silent operation in their builds may prefer the TL-S12W X3 fans, while those seeking more aggressive cooling might accept the minor increase in noise from the Peerless Assassin’s dual-fan setup.

Lighting and Aesthetics

The Peerless Assassin 120 SE includes two high-performance ARGB fans (model TL-C12CW-S) that offer colourful and customizable lighting effects, adding visual appeal to compatible builds. This feature can enhance the aesthetic of gaming or enthusiast systems that support ARGB control. In contrast, the TL-S12W X3 fans do not mention any lighting or RGB features, focusing solely on functional cooling without added visual effects. For users who value aesthetics alongside performance, the Peerless Assassin’s ARGB lighting provides a notable advantage.

Price and Value

The Thermalright Peerless Assassin 120 SE CPU Cooler is priced at C$48.90, representing a full CPU cooling solution with heatsink and dual ARGB fans. The TL-S12W X3 fan package costs C$19.59 and includes three fans, mounting screws, and an instruction manual, making it an economical option for those seeking quiet, versatile 120mm fans to supplement existing cooling setups. While the Peerless Assassin offers a more complete and higher-performance product, the TL-S12W X3 provides good value for case or additional cooling at less than half the price of the Peerless Assassin. Buyers should weigh the need for a full CPU cooler versus supplemental fans when considering cost.

Versatility and Use Cases

The TL-S12W X3 fans are versatile, suitable for case ventilation, liquid cooler radiator fans, or as supplemental fans on CPU coolers, providing flexible integration into various systems. Their 4-pin PWM control and long cables support broad compatibility across PC builds. The Peerless Assassin 120 SE, as a dedicated CPU cooler, is best suited for users looking for an all-in-one air cooling solution for their CPU with advanced heat dissipation and lighting features. It is less adaptable outside of CPU cooling due to its size and mounting requirements. In summary, the TL-S12W X3 fans offer multi-purpose utility, while the Peerless Assassin is specialized for high-performance CPU cooling.

Which should you buy?

If you need a comprehensive CPU cooling solution with advanced heat dissipation, dual ARGB fans, and support for a wide range of Intel and AMD sockets, the Thermalright Peerless Assassin 120 SE CPU Cooler at C$48.90 is the clear choice. It provides higher airflow, a dual tower heatsink, and aesthetic lighting for gaming or enthusiast builds. However, if you are looking for affordable, quiet, and versatile 120mm fans to supplement your existing cooling system or improve case airflow, the Thermalright TL-S12W X3 CPU Fan 120mm Case Cooler Fan package, including three fans for C$19.59, offers excellent value and flexibility. Your decision should hinge on whether you want a full CPU cooler or additional fans to complement your setup.
