Overview of the Products

In this comparison, we’ll examine the Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler and the Thermalright LGA1851 CPU Contact Frame. The former is a high-performance CPU cooler designed for optimal heat dissipation, while the latter serves a specific purpose as a contact frame to prevent CPU warping. The Assassin X 120R is priced at $22.90, whereas the LGA1851 CPU Contact Frame is significantly cheaper at $9.99, making it about 56% less expensive.

Features and Performance

The Thermalright Assassin X 120R boasts a powerful 2000RPM PWM fan, designed to adjust its speed based on the motherboard's temperature for effective cooling without manual adjustment. This cooler features four heat pipes utilizing AGHP technology for improved heat dissipation efficiency, ensuring that high-performance CPUs can operate at optimal temperatures. The aesthetic appeal is enhanced with its ARGB lighting, which can synchronize with the motherboard for a visually appealing setup.

In contrast, the Thermalright LGA1851 CPU Contact Frame focuses on maintaining CPU integrity. It is not a cooling solution but a replacement for the original buckle, designed specifically for Intel Core Ultra Series CPUs. This frame is crafted from durable aluminum, aiming to prevent CPU warping and maintain optimal contact pressure. While it does not provide cooling features, it serves a crucial role in CPU stability.

Design and Build Quality

The design of the Thermalright Assassin X 120R is both functional and visually appealing. With a height of 151mm, it is compatible with most cases, and its digital screen adds a modern touch. The construction utilizes a combination of PBT and PC materials, along with silicone corner pads to minimize noise. The ARGB lighting further enhances its aesthetic value, making it suitable for gamers and PC enthusiasts who appreciate a stylish build.

On the other hand, the Thermalright LGA1851 CPU Contact Frame is built for practicality. Its all-aluminum construction is robust and designed to withstand wear and tear. The anodizing and sandblasting processes ensure a durable finish, resistant to scratches. While it lacks the flashy features of the Assassin X 120R, its straightforward design is focused on functionality, providing essential support for Intel CPUs.

Compatibility

The Thermalright Assassin X 120R is compatible with a wide range of CPU sockets, including AM4/AM5 and Intel LGA1700/1851/1150/1151/1200. This broad compatibility makes it a versatile choice for various builds. Its high-performance features are suitable for users looking to overclock or run demanding applications, ensuring that it can handle a wide array of setups.

Conversely, the Thermalright LGA1851 CPU Contact Frame is specifically designed for Intel Core Ultra Series CPUs that utilize the LGA1851 socket. While its compatibility is limited compared to the Assassin X 120R, it is essential for users with this specific socket type, ensuring that their CPU remains stable and adequately supported.

Price Comparison

The pricing difference between these two products is significant. The Thermalright Assassin X 120R is offered at $22.90, while the Thermalright LGA1851 CPU Contact Frame is priced at $9.99. This means that the contact frame is about 56% cheaper than the cooler. For users on a budget, the LGA1851 frame provides a cost-effective solution for maintaining CPU integrity without the need for a full cooling system.

However, it’s important to consider the functionality each product offers. While the Assassin X 120R may be more expensive, it provides comprehensive cooling solutions that are essential for high-performance computing. In contrast, the LGA1851 frame is a specialized product that serves a very specific need, making it a worthwhile investment for users who require it.

User Experience

Users of the Thermalright Assassin X 120R often commend its effective cooling performance and quiet operation, thanks to its PWM fan. The installation process is typically straightforward, and the added aesthetic appeal of the ARGB lighting enhances the overall user experience. The digital screen also provides useful information, further adding to its functionality.

On the other hand, the Thermalright LGA1851 CPU Contact Frame is appreciated for its solid construction and effectiveness in preventing CPU warping. Users find it easy to install, and the included L-shaped screwdriver and screws make the process hassle-free. However, as it does not offer any cooling features, it is generally viewed as an essential accessory rather than a standalone upgrade.

Which should you buy?

Choosing between the Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler and the Thermalright LGA1851 CPU Contact Frame ultimately depends on your specific needs. If you require a high-performance cooling solution that offers both efficiency and aesthetic appeal, the Assassin X 120R is the clear choice at $22.90. However, if you own a CPU with an LGA1851 socket and are looking to ensure proper contact and prevent overheating, the LGA1851 CPU Contact Frame at $9.99 is a practical and cost-effective option, providing essential support without the need for an elaborate cooling system.
