Noctua NH-L12S vs Thermalright Assassin X 120R Digital ARGB White CPU Cooler Air with 4X6mm HeatPi

Overview of the Noctua NH-L12S

The Noctua NH-L12S is a compact, premium-quality low-profile CPU cooler priced at C$87.95. Ideal for ITX and HTPC systems, it has a total height of just 70mm, making it a great choice for builds with limited space. The NH-L12S is the successor to the award-winning NH-L12, designed to offer efficient cooling for CPUs with moderate heat loads.

This cooler features a highly optimised NF-A12x15 120mm fan that includes PWM support and a Low-Noise Adaptor for automatic speed control, which ensures ultra-quiet operation. Additionally, it comes with high-end NT-H1 thermal paste and a SecuFirm2 mounting system that simplifies installation on a variety of Intel and AMD sockets.

Overview of the Thermalright Assassin X 120R

In stark contrast, the Thermalright Assassin X 120R is an affordable CPU cooler with a significantly lower price point of C$28.39. This cooler features a unique combination of heat dissipation technology, including a 4-heat pipe single tower design and a 2000RPM high-speed fan. The Assassin X 120R is built with a digital screen top cover that displays CPU and graphics card temperatures, allowing users to monitor system performance easily.

Equipped with advanced AGHP heat pipe technology, the Assassin X 120R aims to enhance heat dissipation while minimizing the impact of mounting orientation. Its fan features a PWM function for automatic speed adjustments based on temperature, ensuring performance without manual intervention.

Cooling Performance

When it comes to cooling performance, the Noctua NH-L12S excels with its advanced fan design and low-profile build. The NF-A12x15 fan is engineered for optimal airflow and noise control, making it suitable for systems where sound levels are a concern. This cooler is especially effective for CPUs with moderate heat loads, such as the AMD Ryzen 7950X3D and Intel 285K.

Conversely, the Thermalright Assassin X 120R uses a 2000RPM fan that provides aggressive cooling performance, especially for users who demand higher airflow. The combination of its four heat pipes and a digital display adds functionality, making it a versatile choice for gamers and high-performance builds. However, its cooling efficiency may not match the premium features offered by the NH-L12S in quieter environments.

Noise Levels

Noise levels are crucial in a CPU cooler, especially for users aiming for a silent build. The Noctua NH-L12S is designed with ultra-quiet operation in mind. The Low-Noise Adaptor reduces fan speed automatically, ensuring that noise levels remain minimal. This makes it an excellent choice for users who prioritise a quiet computing environment.

On the other hand, the Thermalright Assassin X 120R, while equipped with noise-reduction features like silicone corner pads, is primarily focused on performance. Its 2000RPM fan may generate more noise under load compared to the NH-L12S, making it less ideal for noise-sensitive applications.

Installation Process

The installation process for the Noctua NH-L12S is straightforward, thanks to its SecuFirm2 mounting system. This system allows for easy attachment to various Intel and AMD sockets, including LGA1700 and AM4, which is beneficial for users looking for a hassle-free setup. Furthermore, the inclusion of high-end NT-H1 thermal paste simplifies the installation process even further.

In comparison, the Thermalright Assassin X 120R also boasts ease of installation, compatible with dual platforms. However, the requirement for the TRCC software to fully utilise the digital screen may complicate the initial setup for some users. It’s essential to ensure that all connections are made correctly before installation, which may not be as user-friendly as the NH-L12S.

Aesthetic Appeal

Aesthetics play a role in many builds, and here, the Thermalright Assassin X 120R stands out with its digital screen top cover. This feature not only enhances its visual appeal but also provides real-time monitoring of CPU and GPU temperatures, making it a visually functional addition to any setup.

In contrast, while the Noctua NH-L12S has a more utilitarian design, it is classic and understated. The NH-L12S is designed primarily for performance rather than flashy aesthetics. Those who prefer a subtle look may appreciate its sleek lines and neutral colour scheme.

Price Comparison

The price difference between the two coolers is significant, with the Noctua NH-L12S retailing at C$87.95 and the Thermalright Assassin X 120R priced at only C$28.39. This makes the Thermalright cooler a more budget-friendly option, appealing to gamers and users who need solid performance without breaking the bank.

However, it is essential to consider what you are getting for the price. The NH-L12S offers premium features, better noise control, and higher overall cooling performance, which may justify its higher price for users looking for quality and reliability in their cooling solutions.

Which should you buy?

Ultimately, the choice between the Noctua NH-L12S and the Thermalright Assassin X 120R depends on your specific needs and budget. If you prioritise low noise levels, high cooling performance, and easy installation, the Noctua NH-L12S is the superior choice, albeit at a higher price of C$87.95. On the other hand, if you're looking for an affordable cooling solution with decent performance and unique features like a digital display, the Thermalright Assassin X 120R at C$28.39 presents a compelling option.
