Overview of Thermalright Peerless Assassin 120 SE V2

The Thermalright Peerless Assassin 120 SE V2 is engineered for extreme CPU cooling performance, making it a robust option for high-demand systems. With a price tag of C$54.90, it boasts dual thickened PWM fans that generate a maximum airflow of 88.19 CFM and operate at a noise level of 29.5 dB(A). This cooler supports a variety of Intel and AMD sockets and incorporates AGHP GEN 5.0 technology, featuring 6×6mm heat pipes that enhance its cooling capabilities. The design also includes a copper base for improved heat dissipation, making it suitable for CPUs with a TDP of up to 265 watts.

Cooling Performance Comparison

The cooling performance of these two models prominently differs, with the Peerless Assassin 120 SE V2 exhibiting superior specifications. With a maximum airflow of 88.19 CFM, it outperforms the Assassin X 120R SE V2's maximum airflow of 66.17 CFM by approximately 33%. This increase in airflow can significantly impact thermal management, especially in high-performance computing scenarios. Moreover, the Peerless model’s TDP rating of 265 watts indicates its ability to handle more powerful CPUs, making it more suitable for overclocking and demanding applications.

Noise Levels and Acoustic Performance

When it comes to noise levels, the Thermalright Assassin X 120R SE V2 is the quieter option, operating at a maximum noise level of 25.6 dB(A). In contrast, the Peerless Assassin 120 SE V2 operates at a noise level of 29.5 dB(A), making it approximately 15% louder. This difference may be significant for users prioritizing a silent computing environment, such as those who use their PCs for content creation or gaming in quiet settings. Thus, if noise is a critical factor, the Assassin X 120R SE V2 presents a distinct advantage.

Build Quality and Design

Both models showcase impressive build quality, but they differ in design and materials. The Thermalright Assassin X 120R SE V2 features a height of 148mm, making it compatible with medium-sized cases without obstructing memory installation. In contrast, the Peerless Assassin 120 SE V2 measures 155mm in height, which could pose compatibility issues in smaller cases. Furthermore, the Peerless model uses a thicker fan (28mm vs. 25mm) that may contribute to its increased cooling efficiency but may also limit case compatibility.

Installation and Compatibility

Both coolers provide compatibility with a range of Intel and AMD sockets, making them versatile options for various builds. The Assassin X 120R SE V2 supports Intel sockets LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA1700, and AMD AM4/AM5. The Peerless Assassin 120 SE V2 supports Intel LGA1851, LGA1700, LGA1200, LGA115X, and AMD AM4/AM5. Each cooler includes the necessary mounting plates and fasteners, simplifying the installation process. However, users should consider their specific CPU socket type when choosing between these two models.

Price Comparison

The pricing of the two coolers presents a considerable difference, with the Thermalright Assassin X 120R SE V2 retailing for C$23.59, significantly lower than the C$54.90 price tag of the Thermalright Peerless Assassin 120 SE V2. This 133% price increase for the Peerless model reflects its advanced features and higher cooling capacity. For budget-conscious consumers, the Assassin X 120R SE V2 offers substantial value, while those seeking top-tier performance may find the investment in the Peerless model justified.

Which should you buy?
