Noctua NH-U9S vs Thermalright Assassin X 120R Digital ARGB Black

Overview of the Noctua NH-U9S and Thermalright Assassin X 120R

The Noctua NH-U9S is a premium CPU cooler priced at $69.95, while the Thermalright Assassin X 120R is significantly cheaper at $24.90. The price difference of about 179% makes the Thermalright a budget-friendly option. However, each cooler has unique features that cater to different user needs and preferences.

Design and Build Quality

The Noctua NH-U9S boasts a compact single-tower design that measures only 125mm in height, making it an excellent choice for small form factor builds. Its design ensures compatibility with case, RAM, and PCIe slots, which is ideal for users with limited space. In contrast, the Thermalright Assassin X 120R features a slightly larger design at 151mm, which can accommodate most cases while still providing a robust cooling performance. Both coolers are built to high standards, but Noctua’s longer warranty of six years reflects its confidence in build quality.

Cooling Performance

Cooling performance is a critical factor for any CPU cooler, and both products excel in this area, albeit in different ways. The Noctua NH-U9S utilizes an optimized NF-A9 92mm fan that supports PWM for automatic speed control, ensuring ultra-quiet operation. The fan is tailored for strong cooling performance while maintaining low noise levels. On the other hand, the Thermalright Assassin X 120R features a high-speed 2000RPM fan that delivers impressive air volume at 70.84CFM. While the Noctua focuses on silent operation, the Thermalright prioritizes maximum cooling efficiency, which may appeal to gamers and heavy users.

Compatibility

In terms of compatibility, both coolers support a wide range of Intel and AMD sockets. The Noctua NH-U9S is compatible with Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5 & AM4 motherboards. The Thermalright Assassin X 120R also supports multiple platforms, including Intel LGA 1851, LGA 1700, LGA 1150, LGA 1151, LGA 1155, LGA 1156, and LGA 1200, as well as AMD AM4 and AM5. With this extensive compatibility, both coolers can cater to a variety of builds, but the Noctua cooler’s offset mounting option adds an extra layer of efficiency.

Noise Levels

Noise levels are crucial for users who prioritize a quiet computing environment. The Noctua NH-U9S is known for its ultra-quiet operation due to the low-noise adaptor and optimized fan design, making it suitable for HTPCs or environments where silence is paramount. In contrast, the Thermalright Assassin X 120R has a maximum operating noise of 29.8dB(A), which is relatively quiet but may be noticeable under load. Users should consider their noise tolerance when choosing between these two coolers.

Aesthetics and Features

Aesthetically, the Noctua NH-U9S features a classic brown and beige design that is iconic for the brand, appealing to users who appreciate a distinctive look. In contrast, the Thermalright Assassin X 120R comes with a modern digital screen top cover that displays CPU temperature, CPU usage, and graphics card temperature. This feature not only adds functionality but also enhances the visual appeal for users who enjoy RGB lighting and real-time monitoring.

Price Comparison

The price difference between the two coolers is quite significant, with the Noctua NH-U9S retailing at $69.95, while the Thermalright Assassin X 120R is priced at just $24.90. This makes the Thermalright approximately 179% cheaper than the Noctua cooler. While the lower pricepoint of the Thermalright may attract budget-conscious consumers, it is essential to consider the performance and features each cooler offers at their respective price points.

Which should you buy?

Deciding between the Noctua NH-U9S and the Thermalright Assassin X 120R ultimately depends on your specific needs and budget. If you prioritize silent operation and build quality, the Noctua NH-U9S is the better choice, especially given its six-year warranty. However, if you are looking for a more affordable option with strong cooling performance and modern aesthetics, the Thermalright Assassin X 120R is an excellent value. Each cooler serves its purpose well, so consider your priorities before making a decision.
