Thermalright Assassin X 120R Digital ARGB Black CPU Cooler vs Noctua NH-L9x65 chromax.Black

Overview of CPU Coolers

When it comes to CPU coolers, the Thermalright Assassin X 120R Digital ARGB Black and the Noctua NH-L9x65 chromax.Black offer distinct advantages tailored to different builds. The Thermalright cooler is priced at C$32.90, making it an affordable option for users seeking higher performance, while the Noctua model is priced at C$101.95, aimed at compact, low-profile builds.

The Thermalright Assassin X 120R features a robust design with a height of 151mm, making it compatible with most cases, while the Noctua NH-L9x65 is designed for compact builds with a total height of only 65mm. This makes the Noctua ideal for small form factor cases, but the Thermalright offers superior cooling capacity.

Design and Aesthetics

In terms of design, the Thermalright Assassin X 120R Digital ARGB Black incorporates a stylish digital ARGB effect, allowing for a rich lighting experience that can sync with the motherboard. This cooler's top cover enhances its overall aesthetic appeal, combining performance with visual flair.

On the other hand, the Noctua NH-L9x65 chromax.Black features an all-black design that gives it a sleek, modern look. Its compact 95x95mm footprint ensures it does not obstruct RAM or PCIe slots, which is essential for maintaining a clean build. While both coolers have their visual strengths, the Thermalright stands out with its ARGB capabilities.

Cooling Performance

The Thermalright Assassin X 120R is designed to deliver impressive cooling performance, with a fan speed of 2000 RPM and a wind pressure of 2.63mm H2O. It can move an air volume of 70.84 CFM while maintaining a noise level of 29.8 dB(A), making it effective for dissipating heat under load.

Conversely, the Noctua NH-L9x65 employs a highly optimised NF-A9x14 slim fan, which operates quietly due to its PWM support and low-noise adaptor. Although it is tailored for low to moderate heat dissipation, it provides sufficient cooling for CPUs with a lower thermal output. In comparison, the Thermalright is more suitable for high-performance CPUs.

Installation and Compatibility

The Thermalright Assassin X 120R offers wide compatibility, supporting Intel's 14th and 15th Gen processors as well as AMD Ryzen 7000 series CPUs. The installation process is straightforward, with accessories included for ease of use.

In contrast, the Noctua NH-L9x65 is also designed for easy installation, featuring the SecuFirm2 mounting system for Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM4 and AM5 sockets. Its compact design allows it to be mounted in tight spaces without hassle, making it ideal for users with smaller setups. While both coolers are user-friendly, the Thermalright has a broader compatibility range.

Noise Levels

Noise levels are crucial for many users, especially in quiet environments. The Thermalright Assassin X 120R operates at a maximum noise level of 29.8 dB(A), which is relatively quiet for a cooler with high airflow.

The Noctua NH-L9x65, designed with noise minimisation in mind, is equipped with a low-noise adaptor that allows for automatic speed control, ensuring ultra-quiet operation. While both coolers are designed to operate quietly, the Noctua may have a slight edge due to its emphasis on low-noise performance, making it more suited for HTPC or small form factor builds where noise is a concern.

Thermal Paste and Accessories

The Thermalright Assassin X 120R does not specify whether it comes with thermal paste, which is an essential component for effective heat transfer between the CPU and cooler. This could be a consideration for users who may need to purchase thermal paste separately.

In contrast, the Noctua NH-L9x65 includes high-end NT-H1 thermal paste, which is well-regarded in the industry for its performance. This inclusion simplifies the installation process and provides users with a quality product right out of the box. Thus, for those who prefer a complete package, the Noctua may be more appealing.

Price Point

The price difference between the two coolers is significant, with the Thermalright Assassin X 120R priced at C$32.90 and the Noctua NH-L9x65 at C$101.95. This makes the Thermalright a more budget-friendly option, appealing to users looking for efficient cooling without a hefty price tag.

However, the Noctua's higher price reflects its premium features, compact design, and low-noise operation, making it suitable for enthusiasts who prioritise these aspects in their builds. Thus, potential buyers should weigh their budget against the specific features they value most.

Which should you buy?

Choosing between the Thermalright Assassin X 120R Digital ARGB Black and the Noctua NH-L9x65 chromax.Black ultimately depends on your specific needs and build requirements. If you're looking for a budget-friendly cooler with excellent performance and ARGB aesthetics, the Thermalright is an outstanding choice. However, if you prioritise a compact design, low noise, and premium materials, the Noctua is worth the investment. Both coolers have their unique strengths, making them suitable for different types of users and builds.
