Price Comparison

When it comes to pricing, the Thermalright SI-100 White ARGB CPU Air Cooler is significantly more affordable at C$35.90 compared to the Thermalright Peerless Assassin 120 Vision MAX ARGB Black CPU Air Cooler, which retails for C$78.59. This price difference of C$42.69 can be a deciding factor for budget-conscious consumers or those building a system without extensive cooling needs. Despite the lower price, the SI-100 still offers respectable features that cater to users of small to medium-sized cases, while the Peerless Assassin focuses on high-performance cooling for more demanding setups.

Cooling Performance

In terms of cooling performance, the Thermalright Peerless Assassin 120 Vision MAX stands out with its dual-tower design and two fans capable of reaching speeds of 2150 RPM. This configuration delivers an impressive airflow of 69 CFM, which is essential for high-performance CPUs. The SI-100, while competent, operates at a slightly lower fan speed of 2000 RPM, achieving a maximum airflow of 72.37 CFM. Both coolers maintain a noise level of ≤27 dB(A), making them relatively quiet. However, the Peerless Assassin’s advanced heat pipe technology, utilizing six pure copper heat pipes, gives it an edge in thermal management, particularly for overclocked systems.

Design and Aesthetics

The design of the Thermalright Peerless Assassin 120 Vision MAX is noted for its dual-tower structure and a striking magnetically attached top cover featuring a 5-inch IPS LCD screen. This not only enhances its aesthetic appeal but provides real-time monitoring of system performance. In contrast, the SI-100 has a simpler design, featuring a height of just 100mm, making it suitable for compact builds. While the SI-100 employs a white ARGB lighting scheme, the Peerless Assassin’s matte black finish and more sophisticated design may attract users looking for a more premium look in their builds.

Compatibility

Both coolers offer extensive compatibility across different CPU sockets. The Thermalright SI-100 supports Intel's latest sockets, including LGA 1700 and AMD's AM4/AM5 platforms, making it versatile for various builds. Meanwhile, the Peerless Assassin also boasts broad compatibility but is specifically designed to accommodate taller RAM heat spreaders and GPUs due to its height of 164mm. Users building high-performance systems with larger components may find the Peerless Assassin more suitable, while those with smaller cases will appreciate the compact dimensions of the SI-100.

Installation Process

Installation can be a critical factor for many users, and both coolers come with metal fasteners for easy setup. The SI-100, with its 100mm height, is particularly user-friendly for tight spaces, allowing for straightforward installation in small to medium cases. The Peerless Assassin, while taller, is designed to maintain compatibility with mainstream ATX cases and is also relatively easy to install. Both products come equipped with required mounting hardware, ensuring that users can get their systems up and running without unnecessary hassle.

Longevity and Reliability

Longevity is an important aspect for any cooling solution, and both Thermalright models utilize advanced bearing technology. The Peerless Assassin features S-FDB V2 bearings, which are known for their durability, ensuring that the fans provide consistent performance over time. The SI-100, on the other hand, also employs S-FDB v2.0 bearings, with a stated operational lifespan of up to 20,000 hours. This means that both coolers are built to last, but users may lean towards the Peerless Assassin for its slightly more robust construction and advanced cooling features.

Noise Levels

In terms of noise levels, both the Thermalright Peerless Assassin 120 Vision MAX and the SI-100 maintain a quiet operation, with maximum noise levels of ≤27 dB(A) and ≤27.7 dB(A) respectively. This makes both coolers ideal for users who value a silent computing experience. However, the Peerless Assassin's superior airflow and cooling capacity suggest that it may be able to maintain low temperatures with potentially less fan speed, thereby reducing noise even further during heavy loads.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 Vision MAX ARGB Black and the Thermalright SI-100 White ARGB comes down to your specific needs and budget. If performance and advanced features are your priorities, and you’re willing to invest a little more, the Peerless Assassin offers superior cooling capacity and innovative design. However, if you're looking for a reliable and cost-effective solution for a smaller build, the SI-100 provides excellent value without compromising on essential features. Ultimately, both coolers are solid choices, but the best one for you will depend on your specific requirements and budget constraints.
