Pricing Comparison

The Thermalright AXP90 X36 Black Low Profile CPU Air Cooler is priced at C$26.90, making it the more economical choice compared to the Thermalright SI-100 White ARGB CPU Air Cooler, which retails for C$35.90. The price difference of C$9.00 could be significant for budget-conscious consumers looking for effective cooling solutions without breaking the bank. While both products are from the same brand, the AXP90 X36 offers a more affordable entry point for those needing a reliable cooler.

Design and Aesthetics

In terms of design, the Thermalright SI-100 White ARGB CPU Air Cooler features an eye-catching white finish along with ARGB lighting, which adds a modern touch to any build. This cooler measures 120mm in length, 108mm in width, and 100mm in height, making it suitable for various setups. On the other hand, the AXP90 X36 Black has a low-profile design that is compact but lacks any RGB lighting, appealing more to those who prefer a minimalist aesthetic. The choice between these coolers may come down to whether the user values visual flair or a simpler appearance.

Performance Features

Performance-wise, the Thermalright SI-100 employs advanced AGHP 3.0 technology, which includes 6x6mm heat pipes that effectively solve the inverse gravity effect in different orientations. This cooler offers a fan speed of up to 2000 RPM and can achieve an airflow of 72.37 CFM, while maintaining a noise level of less than 27.7 dB(A). In comparison, the AXP90 X36 lacks specified performance metrics in the provided data, making it difficult to evaluate its cooling capabilities against the SI-100. Users looking for a more technically advanced cooling solution with proven specifications might lean towards the SI-100.

Installation and Compatibility

The Thermalright SI-100 is designed for versatility, supporting a wide range of CPU sockets, including Intel's 1150 to 2066 and AMD's AM4 and AM5. It comes equipped with metal fasteners for easy installation, ensuring compatibility across various setups. The AXP90 X36 also likely offers compatibility with standard CPU sockets, but specific details are absent from the data provided. This makes the SI-100 a more appealing option for users who want assurance of compatibility with their existing hardware.

Build Quality and Materials

The Thermalright brand is known for its commitment to high-quality materials, and the SI-100 is no exception. It utilises industrial-grade PBT+PC materials, which promise durability and reliability over extended use, with S-FDB v2.0 bearings designed for longevity. While the AXP90 X36's build quality is also expected to be good given the brand's reputation, specific material details and durability claims are not available, which may affect buyer confidence. The SI-100’s industrial build quality could justify its higher price point for those prioritising longevity.

Noise Levels

When it comes to noise levels, the Thermalright SI-100 maintains a quiet operation with a maximum noise level of just 27.7 dB(A) at full fan speed. This low noise output is ideal for users who appreciate a quieter computing environment. The AXP90 X36 does not provide any noise specifications, leaving uncertainty about its performance in this critical area. For users sensitive to noise, the SI-100 presents a clear advantage, ensuring efficient cooling without excessive sound.

Brand Reputation

Thermalright has over 20 years of experience in the computer accessories market and is well-regarded in both domestic and international circles. Known for their focus on R&D and high-quality products, both coolers benefit from this established reputation. However, the SI-100 is designed with specific techniques and features, such as the AGHP technology, that indicate a more advanced level of engineering. Choosing either product means opting for a reputable brand, but the enhanced features of the SI-100 may resonate more with tech enthusiasts.

Which should you buy?

Ultimately, the choice between the Thermalright AXP90 X36 Black Low Profile CPU Air Cooler and the Thermalright SI-100 White ARGB CPU Air Cooler depends on your specific needs and preferences. If you are looking for the most budget-friendly option without specific performance metrics, the AXP90 X36 at C$26.90 may suit your needs. However, if advanced cooling performance, aesthetic appeal, and build quality are priorities, the SI-100 at C$35.90 offers a more comprehensive package with proven specifications. Consider your budget, aesthetic preferences, and performance requirements when making your decision.
