Overview of the Products
In this comparison, we will explore the Thermalright AXP90 X36 Low Profile ITX CPU Cooler and the Thermalright LGA1851 CPU Contact Frame. The AXP90 X36 is a compact CPU cooler designed for low-profile builds, while the LGA1851 CPU Contact Frame serves as a specialized accessory aimed at enhancing the performance of Intel's latest CPUs. Priced at $20.39 and $9.99 respectively, these products cater to different needs within the CPU cooling and mounting landscape.
Design and Build Quality
The design of the Thermalright AXP90 X36 emphasizes a compact profile, standing at just 36mm tall, making it an ideal choice for ITX cases where space is limited. It boasts a premium-quality all-metal platform with a nickel plating process that enhances corrosion resistance. In contrast, the Thermalright LGA1851 CPU Contact Frame is made from durable aluminum alloy, featuring a gold anodizing sandblasting process that prevents scratching. While both products prioritize durability, the AXP90 X36 offers a more complex assembly meant for cooling, whereas the LGA1851 frame focuses on preventing CPU warping.
Performance Features
The Thermalright AXP90 X36 is equipped with four 6mm AGHP heat pipes that optimize heat dissipation while maintaining noise levels at a pleasing 22.4 DBA. This makes it suitable for users who value a silent operation alongside effective cooling. On the other hand, the LGA1851 CPU Contact Frame is designed to optimize CPU contact pressure, addressing the common issue of CPU overheating and warping. While the AXP90 X36 directly impacts thermal performance through active cooling, the LGA1851 frame enhances stability and reliability in CPU mounting.
Compatibility
The AXP90 X36 is versatile in terms of compatibility, supporting a variety of sockets including Intel's LGA1150, LGA1151, LGA1200, LGA1700, and LGA1851, as well as AMD's AM4 and AM5. This broad compatibility makes it an excellent choice for a range of builds. Conversely, the LGA1851 CPU Contact Frame is specifically designed for Intel's Core Ultra Series CPUs with LGA1851 sockets. While the frame is highly focused, its specialization limits its versatility compared to the AXP90 X36.
Pricing and Value
When it comes to pricing, the Thermalright AXP90 X36 is available at $20.39, which is about 104% more expensive than the LGA1851 CPU Contact Frame priced at $9.99. This price difference reflects the complexity and functionality of the AXP90 X36 as a complete cooling solution, while the LGA1851 frame serves as an accessory. For users on a budget or those specifically needing a contact frame, the LGA1851 offers an economical choice without compromising on quality.
Installation Process
The installation of the Thermalright AXP90 X36 is straightforward, thanks to its all-metal platform and included back plate fastener, allowing for easy mounting in cramped spaces. However, it does require some technical knowledge to ensure optimal performance. In comparison, the LGA1851 CPU Contact Frame comes with an L-shaped screwdriver and screws for installation, making it user-friendly and accessible, even for beginners. This ease of installation may appeal to users looking for a quick fix without the need for extensive cooling solutions.
Target Audience
The Thermalright AXP90 X36 is best suited for PC builders who prioritize cooling performance in small form factor cases, such as ITX builds. Its compact design and effective cooling capabilities make it a go-to choice for gamers and professionals alike. In contrast, the LGA1851 CPU Contact Frame targets users who own Intel Core Ultra Series CPUs and are looking to enhance their CPU's mounting stability. This makes it ideal for individuals who may already have a suitable cooling solution but need to address potential warping issues.
Which should you buy?
Choosing between the Thermalright AXP90 X36 Low Profile ITX CPU Cooler and the Thermalright LGA1851 CPU Contact Frame largely depends on your specific needs. If you are building a compact PC and require an effective cooling solution, the AXP90 X36 is the clear winner with its superior cooling performance and broad compatibility. However, if you own a compatible Intel CPU and are primarily concerned with preventing overheating and warping, the LGA1851 frame offers a specialized solution at a significantly lower price point. Ultimately, assess your requirements to determine which product aligns best with your build.
