Thermalright SI-100 White ARGB CPU Air Cooler vs Thermalright Phantom Spirit 120 CPU Cooler

Brand Overview

Both the Thermalright SI-100 White ARGB CPU Air Cooler and the Thermalright Phantom Spirit 120 CPU Cooler come from the reputable Taiwanese brand Thermalright, which has over 20 years of experience in developing computer accessories. While both products share a commitment to quality and innovation, they cater to slightly different segments of the CPU cooler market. The SI-100 focuses on a compact design suitable for smaller cases, while the Phantom Spirit is designed for more extensive cooling capabilities with advanced features.

Design and Dimensions

The Thermalright SI-100 has a compact dimension of 120(L)x108(W)x100(H)mm and weighs only 0.64kg, making it an excellent choice for small to medium-sized computer cases. In contrast, the Phantom Spirit 120 is larger, measuring 125(L)x135(W)x157(H)mm and weighing 0.945kg. The additional height and weight of the Phantom Spirit allow for enhanced heat dissipation capabilities, making it more suitable for high-performance builds where space is less of a concern.

Cooling Performance

In terms of cooling performance, the Thermalright SI-100 boasts a PWM fan capable of spinning at 2000 RPM, delivering an impressive airflow of 72.37 CFM while maintaining a noise level of 27.7 dB(A). The Phantom Spirit, however, features dual fans operating at 1500 RPM, producing 66.17 CFM of airflow with a slightly quieter noise level of 25.6 dB(A). While the SI-100 provides higher airflow, the Phantom Spirit’s dual fan configuration can enhance cooling efficiency, particularly under load, by distributing airflow more effectively across the cooler.

Heat Pipe Technology

The Thermalright SI-100 utilises the AGHP 3.0 technique with six 6mm heat pipes to counteract the inverse gravity effect, which is beneficial in various orientations. Meanwhile, the Phantom Spirit takes it a step further with seven 6mm heat pipes using the upgraded 4th generation AGHP technology. This improvement allows the Phantom Spirit to manage heat more efficiently, making it a potentially better option for users who push their CPUs to higher performance levels.

Material and Build Quality

Both coolers are constructed from high-quality materials, including aluminum heat sinks and industrial-grade PBT+PC material. The SI-100 features a straightforward design suitable for most builds, while the Phantom Spirit stands out with its anodized black frosted top and finely carved pure copper base technology, enhancing both aesthetics and thermal performance. The emphasis on build quality in both products ensures durability and reliability over time, but the Phantom Spirit’s premium design may appeal to users looking for a visually striking component.

Compatibility

When it comes to compatibility, both the Thermalright SI-100 and Phantom Spirit support a wide range of CPU sockets. The SI-100 is compatible with Intel sockets from LGA 1150 to 2066 and AMD's AM4 and AM5, making it versatile for various builds. The Phantom Spirit offers similar compatibility, supporting Intel and AMD sockets, thus ensuring that both coolers can accommodate a wide array of processors. This versatility is crucial for users who may upgrade their systems in the future.

Pricing

In terms of cost, the Thermalright SI-100 is priced at C$35.90, making it a budget-friendly option for those seeking effective cooling without breaking the bank. On the other hand, the Phantom Spirit is priced significantly higher at C$49.90. This price difference reflects the additional features and enhanced performance capabilities of the Phantom Spirit, making it a worthy investment for users who require superior cooling for demanding applications.

Which should you buy?

Choosing between the Thermalright SI-100 White ARGB CPU Air Cooler and the Thermalright Phantom Spirit 120 CPU Cooler ultimately depends on your specific needs and budget. If you are looking for a compact, cost-effective solution for a small to medium-sized build, the SI-100 is an excellent choice with its impressive airflow and noise performance. However, if you require advanced cooling capabilities and are willing to invest more for enhanced performance, the Phantom Spirit offers superior heat dissipation, dual fans, and premium materials that justify its higher price.
