Thermalright Peerless Assassin 120 SE V2 CPU Cooler vs Thermalright SI-100 White ARGB CPU Air Cooler

Overview of the Thermalright Peerless Assassin 120 SE V2

The Thermalright Peerless Assassin 120 SE V2 CPU Cooler is designed for those seeking robust cooling performance. Priced at C$54.90, this cooler features dimensions of 125mm x 135mm x 155mm and a weight of 610 grams, making it a significant addition to any build. It is equipped with six 6mm heat pipes, crafted from pure copper, which contribute to its impressive thermal conductivity. The dual thickened PWM fans operate at a maximum speed of 1850 RPM, delivering an airflow of 88.19 CFM while maintaining a noise level of ≤29.5 dB(A). This cooler's technological design and material choices aim to achieve a TDP of up to 265 watts, making it suitable for high-performance CPUs.

Overview of the Thermalright SI-100 White ARGB

The Thermalright SI-100 White ARGB CPU Air Cooler is a more compact alternative, priced at C$35.90. With dimensions of 120mm x 108mm x 100mm and a weight of 640 grams, it is designed to fit smaller cases without compromising performance. This cooler utilises the AGHP 3.0 technique with six 6mm heat pipes, ensuring effective heat dissipation. The PWM fan operates at a maximum speed of 2000 RPM, providing an airflow of 72.37 CFM and a noise level of ≤27.7 dB(A). This makes the SI-100 an excellent choice for users who prioritize low noise without sacrificing cooling efficiency, especially in smaller builds.

Cooling Performance Comparison

When it comes to cooling performance, the Thermalright Peerless Assassin 120 SE V2 holds a significant advantage with a TDP capacity of up to 265 watts, compared to the SI-100's more modest cooling capabilities. The twin fans on the Peerless Assassin, which can push an airflow of 88.19 CFM, outperform the SI-100's single fan at 72.37 CFM. This means that for high-end CPUs or overclocking scenarios, the Peerless Assassin would be the better choice. Conversely, the SI-100’s lower maximum airflow and noise level make it suitable for users with less demanding cooling needs or who prefer a quieter operation.

Size and Compatibility Considerations

In terms of size, the Thermalright SI-100 is more compact, measuring 120mm in length and only 100mm in height, making it an excellent option for smaller cases. This cooler supports a variety of Intel and AMD sockets, including the latest AM5 and LGA 1700. The Peerless Assassin, while larger at 155mm tall, is also compatible with a wide array of sockets, including Intel LGA 1851 and AMD AM4/AM5. Users with limited vertical space in their cases will find the SI-100 to be a more accommodating solution, whereas those with larger cases can benefit from the enhanced cooling of the Peerless Assassin.

Noise Levels and Fan Technology

Noise levels are a crucial factor in cooler performance, especially for users who seek a quiet computing environment. The Thermalright SI-100 boasts a maximum noise level of ≤27.7 dB(A), which is quieter than the Peerless Assassin's ≤29.5 dB(A). This difference, while not vast, could be noticeable in a silent build. The Peerless Assassin features dual fans that enhance cooling but may generate slightly more noise under load. Users who prioritise a quieter operation may lean towards the SI-100, while those requiring superior cooling might tolerate the additional noise from the Peerless Assassin.

Build Quality and Materials

Both products reflect Thermalright's commitment to quality, featuring aluminium fins and copper heat pipes. The Peerless Assassin uses a nickel-plated base and advanced manufacturing techniques to enhance thermal performance, while the SI-100 incorporates industrial-strength materials for durability. The choice of S-FDB bearings in both coolers contributes to their longevity and reliability. However, the Peerless Assassin's heavier construction at 610 grams indicates a more robust design, which may appeal to users looking for durability in high-performance scenarios.

Price and Value Proposition

With a price of C$54.90, the Thermalright Peerless Assassin 120 SE V2 is positioned as a premium cooler, offering high-end cooling capabilities. In contrast, the Thermalright SI-100 is more budget-friendly at C$35.90, making it an attractive option for budget-conscious builders or those with less intensive cooling requirements. The value proposition comes down to the intended use: for users needing substantial cooling for demanding CPUs, the investment in the Peerless Assassin may be justified, while casual users may find the SI-100 meets their needs effectively without overspending.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE V2 and the Thermalright SI-100 White ARGB largely depends on your specific needs. If you require high cooling performance and have the space in your case, the Peerless Assassin is the superior choice, especially for overclocked systems with a TDP of up to 265 watts. However, if you have a smaller build and prefer a quieter operation at a lower price point, the SI-100 is a compelling option that does not compromise on essential features. Ultimately, your decision should align with your cooling needs, case compatibility, and budget.
