Thermalright Peerless Assassin 120 SE V2 CPU Cooler vs Thermalright Assassin X 120 SE CPU Air Cooler

Overview of the Products

In this comparison, we will examine the Thermalright Peerless Assassin 120 SE V2 CPU Cooler and the Thermalright Assassin X 120 SE CPU Air Cooler, two offerings from the renowned brand Thermalright. The Peerless Assassin 120 SE V2 is priced at C$54.90, while the Assassin X 120 SE comes in at a more budget-friendly C$25.59. Both coolers are designed to provide efficient cooling solutions for various CPU sockets, but they differ significantly in terms of specifications and performance capabilities.

Design and Dimensions

The Thermalright Peerless Assassin 120 SE V2 boasts dimensions of 125mm x 135mm x 155mm, making it a substantial cooler that supports a wide range of CPUs. In contrast, the Assassin X 120 SE has a more compact design, measuring 125mm x 71mm x 148mm. While both coolers utilize aluminum for their heat sinks, the Peerless Assassin is equipped with six heat pipes, compared to the four found in the Assassin X. This design difference indicates that the Peerless model may offer superior heat dissipation capabilities, making it potentially more suitable for high-performance CPUs.

Cooling Performance

When it comes to cooling performance, the Peerless Assassin 120 SE V2 stands out with a TDP (Thermal Design Power) rating of up to 265W, which is significantly higher than the Assassin X's TDP range of 125 to 225W. This higher TDP capacity suggests that the Peerless Assassin can handle more demanding processors without overheating. Additionally, the Peerless model features dual PWM fans that can achieve an airflow of 88.19 CFM, while the Assassin X’s single PWM fan provides an airflow of 66.17 CFM. These figures indicate that the Peerless Assassin is likely to maintain lower temperatures under heavy loads.

Noise Levels

Noise levels are an important consideration for many users, and both coolers aim to operate quietly. The Peerless Assassin 120 SE V2 has a noise level of ≤29.5 dB(A), while the Assassin X 120 SE is slightly quieter with a noise level of ≤25.6 dB(A). Although the difference in noise levels may not be significant, users who prioritise a silent environment might find the Assassin X more appealing. However, the cooling performance of the Peerless model may justify its slightly higher noise output, especially for those using high-performance CPUs.

Fan Technology

The Peerless Assassin 120 SE V2 features dual TL-C12C-X28 V2 fans, each measuring 120mm x 120mm x 28mm, which can spin at a maximum speed of 1850 RPM. This configuration enables it to generate substantial airflow and pressure, essential for efficient cooling. On the other hand, the Assassin X 120 SE utilises a single TL-C12C fan that operates at a maximum speed of 1550 RPM. While the Assassin X's fan offers lower RPM and airflow, it is designed for a quieter operation, making it suitable for users who do not push their systems to the limits.

Compatibility

Both coolers offer broad compatibility with various Intel and AMD sockets. The Peerless Assassin 120 SE V2 supports Intel LGA 1851/1700/1200/115X and AMD AM4/AM5, ensuring it can fit a wide range of modern CPUs. Similarly, the Assassin X 120 SE is compatible with Intel 115X/1200/1700/17XX and AMD AM4 sockets. This compatibility is crucial for users looking to upgrade their cooling solution without changing their entire system. However, the additional mounting options in the Peerless model may provide greater flexibility for users with newer processors.

Build Quality and Materials

Both coolers are constructed with quality materials, featuring aluminum for their heat sinks and using various types of copper for heat pipes and bases. The Peerless Assassin 120 SE V2 incorporates a pure copper base and six copper heat pipes, which enhance its thermal conductivity. The Assassin X 120 SE, while also utilizing aluminum and copper, has a slightly lower overall build weight of 0.645 kg compared to the Peerless model's 0.610 kg. This indicates that while both coolers are sturdy, the Peerless Assassin might have an edge in terms of thermal performance due to its design and material choices.

Price and Value

Price is a critical factor for many consumers, and here the differences are substantial. The Peerless Assassin 120 SE V2 is priced at C$54.90, while the Assassin X 120 SE is available for C$25.59. While the Peerless model is more expensive, it offers enhanced cooling performance, a higher TDP rating, and dual fans. For users seeking a budget-friendly option that still delivers decent performance, the Assassin X may be adequate. However, for those who require superior cooling capabilities for high-performance setups, the additional investment in the Peerless model may be justified.

Which should you buy?

Ultimately, the choice between the Thermalright Peerless Assassin 120 SE V2 and the Thermalright Assassin X 120 SE boils down to your specific needs and budget. If you’re looking for maximum cooling performance, compatibility with high-end CPUs, and don’t mind spending a bit more, the Peerless Assassin 120 SE V2 is the clear winner. However, if you are on a tighter budget or require a cooler that operates quietly under moderate loads, the Assassin X 120 SE offers solid performance at a more accessible price point.
