Overview of the ARCTIC Liquid Freezer III Pro 240 A-RGB and Thermalright Assassin X 120R

The ARCTIC Liquid Freezer III Pro 240 A-RGB is a liquid cooler priced at $80.00, while the Thermalright Assassin X 120R is an air cooler available for just $24.90. This significant price difference of about 68% reflects the distinct cooling technologies each product employs. While the ARCTIC model promises advanced water-cooling efficiency, the Thermalright model offers a straightforward air-cooling solution with a digital display to monitor temperatures.

Cooling Performance

When it comes to cooling performance, the ARCTIC Liquid Freezer III Pro uses a 240 mm radiator and an optimized contact pressure distribution for better heat dissipation. It features ARCTIC's P12 Pro fan, which operates quietly and efficiently, especially under load. In contrast, the Thermalright Assassin X 120R utilizes a 120 mm fan that can reach speeds of up to 2000 RPM. While the ARCTIC cooler targets high-performance setups, the Thermalright still delivers respectable heat dissipation, though it may not match the efficiency of a dual-fan liquid cooling system.

Design and Aesthetics

The ARCTIC Liquid Freezer III Pro offers a sleek black design with A-RGB lighting, appealing to gamers and PC builders seeking aesthetic appeal. Its integrated cable management simplifies installation, ensuring a clean build. On the other hand, the Thermalright Assassin X 120R incorporates a digital screen top cover that displays real-time CPU and GPU temperatures, providing both functionality and visual flair. While both coolers focus on aesthetics, the choice boils down to preference—RGB lighting versus a digital display.

Compatibility

The ARCTIC Liquid Freezer III Pro is designed for a wide range of sockets, including AMD AM5/AM4 and Intel LGA1851/1700, ensuring that it will fit many modern builds. Similarly, the Thermalright Assassin X 120R supports both Intel and AMD sockets, including the latest generations, making it accessible for various users. However, the Thermalright requires the use of the motherboard's original backplate for AMD installations, which could complicate setup for some users.

Noise Levels

The ARCTIC Liquid Freezer III Pro is engineered for quiet operation, particularly at low speeds, making it suitable for users who prioritize a silent computing environment. Although specific noise levels are not provided, the performance focus suggests it operates quietly under load. The Thermalright Assassin X 120R, with a maximum noise level of 29.8 dB(A), also emphasizes quiet operation, but its 2000 RPM fan may produce more noise under heavy loads compared to the ARCTIC model.

Installation Ease

The ARCTIC liquid cooler features integrated cable management, which simplifies the installation process by reducing visible clutter. Its design is optimized for easy mounting across various platforms. The Thermalright Assassin X 120R also comes with installation accessories and user-friendly instructions, although the requirement of the original backplate for AMD installations could present a challenge. Users looking for a straightforward installation may find the ARCTIC model slightly more convenient.

Price Comparison

The ARCTIC Liquid Freezer III Pro is priced at $80.00, while the Thermalright Assassin X 120R is significantly cheaper at $24.90. This price difference of about 68% could be a deciding factor for budget-conscious consumers. While the ARCTIC model offers advanced features and cooling performance suitable for high-end builds, the Thermalright is an excellent choice for those seeking basic cooling at a fraction of the cost.

Which should you buy?

In choosing between the ARCTIC Liquid Freezer III Pro and the Thermalright Assassin X 120R, consider your specific needs and budget. If you prioritize high cooling performance, aesthetics, and have a higher budget, the ARCTIC model is a superior choice due to its advanced water-cooling technology and quieter operation. Conversely, if you are looking for an economical air cooler that still provides decent performance and a unique digital display, the Thermalright would be the better option for you. Ultimately, your decision should align with your cooling requirements and how much you are willing to invest in your cooling solution.
