Overview of the Thermalright SI-100 White ARGB CPU Air Cooler
The Thermalright SI-100 White ARGB CPU Air Cooler is designed for users who prioritize aesthetics and performance. Priced at C$35.90, this cooler features a height of just 100mm, allowing it to fit comfortably in smaller cases. It employs AGHP 3.0 technology with six 6mm heat pipes, which is designed to mitigate inverse gravity effects for efficient heat dissipation. The inclusion of S-FDB v2.0 bearings ensures a long service life, rated at up to 20,000 hours. This cooler is compatible with a broad range of Intel and AMD sockets, making it a versatile option for various builds.
Overview of the Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler
The Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler is a more budget-friendly option, retailing at C$29.90. This cooler also incorporates AGHP technology, specifically the upgraded 4th generation, and features six nickel-plated copper heat pipes for improved thermal conductivity. With a fan speed of 1550 RPM and a maximum airflow of 66.17 CFM, it offers effective cooling while maintaining a low noise level of 25.6 dB(A). Its unique fin offset technology allows for installation without height restrictions, making it suitable for systems with tall RAM modules.
Cooling Performance Comparison
In terms of cooling capability, the Thermalright SI-100 White ARGB outperforms the Burst Assassin 120 SE. The SI-100 has a maximum airflow of 72.37 CFM at a fan speed of 2000 RPM, compared to the Burst Assassin's 66.17 CFM and 1550 RPM. This difference in airflow indicates that the SI-100 is better equipped to handle high thermal loads, making it ideal for overclocking or demanding applications. However, the Burst Assassin still offers solid performance for most mainstream users while operating at a quieter level.
Noise Levels and Operation
When comparing noise levels, the Thermalright Burst Assassin 120 SE has a slight edge due to its quieter operation. It operates at a maximum noise level of 25.6 dB(A), while the SI-100 reaches up to 27.7 dB(A). This makes the Burst Assassin a better choice for users who are sensitive to noise, especially in quiet environments. Despite the slight difference, both coolers are designed to maintain a balance between cooling efficiency and acoustic performance.
Design and Aesthetics
Aesthetically, both coolers feature ARGB lighting, but the Thermalright SI-100 White ARGB stands out with its sleek white finish, making it an attractive option for users looking to match their build's colour scheme. The Burst Assassin also features ARGB but is more utilitarian in its design. The SI-100's height of 100mm allows for better compatibility with smaller cases, while the Burst Assassin's design incorporates fin offset technology, ensuring it can fit in configurations where memory height is a concern.
Installation and Compatibility
Both coolers provide broad compatibility with Intel and AMD sockets, including Intel's LGA 1150, 1151, 1155, 1156, 1200, 1700, 1851, and 2066, as well as AMD's AM4 and AM5. However, the Burst Assassin requires the original motherboard backplane for installation, which could complicate the setup process. Conversely, the SI-100 uses metal fasteners for easy installation, making it more user-friendly for those building their systems for the first time.
Value for Money
In terms of value, the Thermalright Burst Assassin 120 SE offers a compelling option at C$29.90, making it a great choice for budget-conscious consumers who still want quality cooling performance. The SI-100, while slightly more expensive at C$35.90, provides additional features and increased cooling efficiency that may justify the price for users with higher performance needs. Ultimately, the choice will depend on the specific requirements and budget of the user.
Which should you buy?
Ultimately, the decision between the Thermalright SI-100 White ARGB and the Thermalright Burst Assassin 120 SE comes down to your specific needs. If you require higher cooling performance and are willing to pay a bit more, the SI-100 is the better choice with its superior airflow and sleek design. However, if you're looking for a quieter, budget-friendly option that still delivers solid performance, the Burst Assassin is an excellent alternative. Your choice will hinge on whether you prioritize performance or price, along with your compatibility and aesthetic preferences.
