Overview of the Products

The Thermalright Assassin X 90 SE V2 CPU Cooler is a comprehensive cooling solution, while the Thermalright LGA1700-BCF Black V2 CPU Retainer serves a specific function. Priced at C$24.90, the CPU cooler is designed for high-performance applications, whereas the retainer, available for C$8.99, is focused on preventing CPU bending during installation. Understanding these distinctions is crucial for making an informed decision based on your cooling requirements.

Design and Build Quality

The design of the Thermalright Assassin X 90 SE V2 CPU Cooler is built around advanced cooling technology featuring a 4x6mm heatpipe configuration and high-quality materials. This cooler measures 94mm in length, 77mm in width, and stands 118mm tall, making it compatible with a wide range of chassis models. In contrast, the Thermalright LGA1700-BCF Black V2 CPU Retainer, made from all-aluminium alloy, measures 54mm by 70mm and is designed specifically to support Intel’s LGA1700 socket. The cooler’s robust design aims to maximize cooling efficiency, while the retainer focuses on ensuring the CPU remains secure during use.

Cooling Performance

The cooling performance of the Thermalright Assassin X 90 SE V2 is notable, featuring a PWM fan capable of reaching speeds of 2200 RPM and airflow of 32.77 CFM. This high-speed fan operates at a noise level of no more than 23.85 dB(A), making it an effective solution for maintaining optimal CPU temperatures. On the other hand, the LGA1700-BCF Black V2 does not directly contribute to cooling performance; instead, it functions to support the CPU against physical stress, ensuring that the cooler can perform effectively without risk of bending the CPU.

Compatibility

When it comes to compatibility, the Thermalright Assassin X 90 SE V2 CPU Cooler supports a variety of CPU sockets, including Intel’s 1150 through 1200 series and AMD’s AM4/AM5. This makes it a versatile choice for users looking to upgrade or build a new system with different CPU platforms. Conversely, the Thermalright LGA1700-BCF Black V2 is specifically designed for Intel’s 12th to 14th generation CPUs, ensuring precise alignment and supporting the weight of the cooler to avoid bending. This means that while one product is broadly compatible, the other is tailored for a specific socket type.

Installation Process

The installation process for the Thermalright Assassin X 90 SE V2 is facilitated by the inclusion of mounting plates and fasteners for various CPU slots, making it straightforward for users to set up. Its design and provided instructions aim to streamline the installation experience. In comparison, the Thermalright LGA1700-BCF Black V2 comes with an L-shaped screwdriver and installation instructions, making it easy to install. The emphasis on user-friendliness in both products highlights Thermalright's commitment to customer satisfaction, but they serve two distinct roles in the assembly of a CPU cooling system.

Price Point Comparison

At C$24.90, the Thermalright Assassin X 90 SE V2 is positioned as an affordable yet effective CPU cooler, offering significant features for its price. In contrast, the Thermalright LGA1700-BCF Black V2 is priced at C$8.99, making it a budget-friendly accessory for users who require additional support for their CPU. The price difference reflects the distinct functions of these products, with the cooler providing comprehensive cooling capabilities and the retainer serving a niche purpose.

Brand Reputation

Thermalright has established itself as a reputable brand in the CPU cooling market with over 20 years of experience. The brand is well-regarded for its commitment to quality and innovation. The Assassin X 90 SE V2 exemplifies this reputation through its advanced technology and durable design. The LGA1700-BCF Black V2 also benefits from this brand credibility, as it reflects Thermalright’s focus on quality and performance, albeit in a more specialized capacity. Trust in the brand is an important factor for consumers when considering these products.

Which should you buy?

Choosing between the Thermalright Assassin X 90 SE V2 CPU Cooler and the Thermalright LGA1700-BCF Black V2 CPU Retainer ultimately depends on your specific needs. If you are looking for a robust cooling solution that enhances performance and supports a variety of CPU sockets, the Assassin X 90 SE V2 is the clear choice at C$24.90. However, if you own an LGA1700 socket CPU and need a reliable tool to prevent bending during installation, the LGA1700-BCF Black V2 at C$8.99 is an excellent option. Both products showcase Thermalright's quality and innovation, ensuring that you can trust either choice for your cooling needs.
