Overview of the Products

The Thermalright Assassin X 120R Digital ARGB Black CPU Cooler is priced at $24.90, while the Thermalright LGA1851 CPU Contact Frame is significantly cheaper at $9.99, making it about 60% less expensive. Both products come from Thermalright, a well-known brand in the CPU cooling sector. However, they serve very different purposes within the realm of computer cooling. The Assassin X 120R is a comprehensive cooling solution, while the LGA1851 Contact Frame is an accessory designed to enhance CPU stability.

Design and Build Quality

The Thermalright Assassin X 120R features a sophisticated design with a digital screen top cover, allowing users to monitor CPU temperature and usage in real-time. Its dimensions are 120x71x151mm, and it incorporates a high-speed 2000RPM fan. In contrast, the LGA1851 CPU Contact Frame is a simple yet robust accessory made of durable aluminum alloy, designed to prevent CPU warping. This frame measures 53.5 x 70 x 6.25 mm and comes with a set of screws and a screwdriver. The overall design of the Assassin X 120R aims for both aesthetics and functionality, while the LGA1851 frame focuses purely on structural integrity.

Cooling Performance

The Thermalright Assassin X 120R is engineered for superior heat dissipation, with a heat dissipation height of 151mm and a wind pressure of 2.63MM H2O. It offers an air volume of 70.84CFM with operating noise levels capped at 29.8dB(A). This means that it not only keeps your CPU cool but does so quietly, making it suitable for both gaming and office environments. On the other hand, the LGA1851 CPU Contact Frame does not contribute directly to cooling performance but instead helps maintain optimal pressure on the CPU to prevent overheating and warping.

Compatibility

The Thermalright Assassin X 120R supports a wide range of sockets, including Intel LGA 1851/1700/1150/1151/1155/1156/1200 and AMD AM4/AM5. This versatility makes it an excellent choice for various builds. The LGA1851 CPU Contact Frame, while not a cooling unit itself, is specifically designed for Intel Core Ultra Series CPUs with LGA1851 sockets. This specificity means that while the frame improves CPU stability, it may not be suitable for users with different socket types.

Installation Process

Installing the Thermalright Assassin X 120R requires some attention to detail due to its multi-component design, but it comes with an installation accessory and is compatible with most cases. Users can follow the provided video or manual for guidance, which simplifies the process. In comparison, the LGA1851 CPU Contact Frame is straightforward to install, requiring only the provided L-shaped screwdriver and screws. This simplicity makes it an attractive option for users looking to enhance their CPU's stability without the complexity of a full cooler installation.

Price Comparison

The price difference between the two products is quite notable. The Thermalright Assassin X 120R is available for $24.90, while the LGA1851 CPU Contact Frame costs only $9.99. This makes the frame approximately 60% cheaper than the cooler. For budget-conscious consumers or those who may not require a full cooling solution, the LGA1851 offers an economical alternative that still addresses CPU stability. However, for those seeking effective cooling, the Assassin X 120R is a more substantial investment.

Target Audience

The Thermalright Assassin X 120R is aimed at gamers and PC builders who require efficient cooling solutions for high-performance CPUs, especially those using Intel or AMD platforms. Its advanced features and aesthetic design cater to users who value both performance and appearance. Conversely, the LGA1851 CPU Contact Frame targets users who may already have a cooling solution but need to enhance the stability of their CPU. This makes it ideal for those looking for a simple, effective upgrade without the need for major changes to their cooling setup.

Which should you buy?

Choosing between the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright LGA1851 CPU Contact Frame depends heavily on your specific needs. If you are looking for a comprehensive cooling solution that combines performance with aesthetic appeal, the Assassin X 120R is the clear winner at $24.90. However, if you already have a cooling solution and simply need to enhance CPU stability, the LGA1851 CPU Contact Frame at $9.99 is an excellent, budget-friendly option. Ultimately, your choice should align with your performance requirements and budget constraints.
