It has been designed to provide optimal airflow with a fan speed ranging from 690 to 1,800 RPM, allowing users to adjust noise and performance levels as needed. Its 154mm height ensures compatibility with a variety of chassis, making it a versatile choice for many builds.

Overview of the Thermalright Assassin X120 Refined SE

In contrast, the Thermalright Assassin X120 Refined SE is a budget-friendly option at $17.90, providing substantial cooling power without breaking the bank. This cooler also features a PWM fan, the TL-C12C, and utilizes AGHP technology with four heat pipes for effective heat management. The Assassin X120 is designed for various socket types, including AMD AM4/AM5 and Intel LGA 1150/1200 series, making it a versatile choice for many users.

At a height of 148mm, the Assassin X120 is slightly shorter than the Hyper 212, which may give it an edge in tighter builds. Its aluminum heatsink cover and a fan speed of up to 1,550 RPM contribute to a maximum airflow of 66.17 CFM while maintaining a low noise level under 25.6 dB(A). This cooler is an excellent option for users looking for an efficient yet quiet cooling solution.

Design and Aesthetics

The Cooler Master Hyper 212 Halo Black boasts a refreshed aesthetic with its all-black design and dual-loop ARGB lighting, which adds a striking visual element to any build. The larger LED rings, which are 50% bigger than previous models, create vibrant lighting effects that can enhance the overall look of a gaming rig.

On the other hand, the Thermalright Assassin X120 Refined SE adopts a more utilitarian design. While it may not feature RGB lighting, its clean and functional appearance is appealing to users who prioritize performance over flashiness. The aluminum heatsink cover is designed for durability and efficient heat transfer, ensuring that it remains effective over time.

Performance Capabilities

When it comes to performance, the Cooler Master Hyper 212 Halo Black excels with its four copper heat pipes that provide superior thermal conductivity. This makes it particularly effective for cooling demanding processors like the AMD Ryzen R7 and Intel i7, ensuring minimal thermal throttling during intense tasks.

The Thermalright Assassin X120 also performs admirably with its four heat pipes and AGHP technology, which helps mitigate the inverse gravity effect. While it may not outperform the Hyper 212 in extreme scenarios, it still offers reliable cooling capabilities, especially for mid-range builds. The fan's maximum airflow of 66.17 CFM ensures that it maintains a stable temperature even under load.

Installation and Compatibility

The Cooler Master Hyper 212 Halo Black is designed with simplified brackets that facilitate easy installation on both AMD AM5 and Intel LGA 1851/1700 platforms. This user-friendly approach allows even novice builders to set it up without much hassle, enhancing its appeal.

The Thermalright Assassin X120 Refined SE also focuses on compatibility, supporting a wide range of socket types. Its installation process is straightforward, thanks to the included metal fasteners for both Intel and AMD platforms. While both coolers provide excellent compatibility, the Hyper 212's design might make it slightly easier for first-time users.

Noise Levels

In terms of noise levels, the Cooler Master Hyper 212 Halo Black operates with a dynamic PWM fan that can adjust speeds between 690 and 1,800 RPM, allowing users to find a balance between performance and noise. This feature is particularly useful for gamers who prefer a quieter environment during intense gaming sessions.

Conversely, the Thermalright Assassin X120 operates at a maximum fan speed of 1,550 RPM, producing noise levels under 25.6 dB(A). This makes it one of the quieter options in its price range, appealing to users who prioritize silent operation. In general, both coolers provide options for users to manage noise levels effectively, though the Hyper 212 offers more flexibility due to its adjustable RPM range.

Price and Value

The Cooler Master Hyper 212 Halo Black is priced at $34.99, while the Thermalright Assassin X120 Refined SE is significantly cheaper at $17.90, making it about 49% less expensive. For budget-conscious consumers or those building entry-level systems, the Thermalright model presents a compelling value proposition.

However, for users seeking advanced features like RGB lighting and superior aesthetics, the Hyper 212 offers a better overall experience, justifying its higher price.
