Dimension comparison
Overview of the Thermalright Assassin X 120 V2 Plus
The Thermalright Assassin X 120 V2 Plus CPU Cooler is designed for efficiency and longevity, featuring a price of C$25.90. This cooler incorporates a unique AGHP technology that employs four 6mm heat pipes to combat the inverse gravity effect, ensuring reliable performance regardless of orientation. Constructed with pure aluminium cooling fins, it aims to achieve high heat dissipation while maintaining a compact footprint of 120(L)x96(W)x154(H)mm. Additionally, the cooler is compatible with a wide range of Intel and AMD sockets, enhancing its versatility.
Overview of the Thermalright Peerless Assassin 120 SE V2
The Thermalright Peerless Assassin 120 SE V2 is a more advanced option priced at C$54.90. It features a larger design with dimensions of 125(L)x135(W)x155(H)mm and utilizes AGHP GEN 5.0 technology, which incorporates six 6mm heat pipes for superior cooling performance. This cooler is built with a combination of aluminium fins on a copper base, which promotes efficient heat transfer. Its dual thickened PWM fans can spin up to 1850 RPM, providing an air flow of 88.19 CFM, making it a compelling choice for users seeking extreme cooling capabilities.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin 120 SE V2 has a clear advantage. With a TDP rating of up to 265 watts, it is designed for more demanding CPU workloads compared to the Assassin X 120 V2. The latter, while effective, does not specify its TDP rating, indicating that it may not be as capable under heavy loads. The Peerless model's six heat pipes versus the four in the Assassin X further contribute to its enhanced thermal management, making it a better choice for overclockers or gamers.
Noise Levels
Both coolers employ S-FDB bearings, which are designed to reduce noise levels. The Thermalright Peerless Assassin 120 SE V2 boasts a noise level of ≤29.5 dB(A), which is relatively quiet for a high-performance cooler. On the other hand, the Assassin X 120 V2 does not specify its noise levels, making it difficult to assess how it compares in this crucial aspect. Users looking for a quiet operation may find more certainty with the Peerless model's documented performance.
Installation and Compatibility
In terms of installation and compatibility, both coolers provide broad support for Intel and AMD sockets. The Assassin X 120 V2 is compatible with Intel's 1150 through 1700 series and AMD's AM4 and AM5 sockets. The Peerless Assassin 120 SE V2 supports a similar range but includes additional compatibility for the LGA 1851 socket. Both products come with the necessary mounting hardware and installation instructions, making them user-friendly options for builders of all experience levels.
Build Quality and Materials
The build quality of both coolers reflects Thermalright's commitment to durability and performance. The Assassin X 120 V2 utilizes pure aluminium for its cooling fins and is engineered with industrial-strength materials for longevity. Conversely, the Peerless Assassin 120 SE V2 features a copper base and pure copper heat pipes, which are known for their superior thermal conductivity. The overall weight of the Peerless model is higher at 610 grams, indicating a more robust construction that may further enhance its cooling capabilities.
Price Consideration
The Thermalright Assassin X 120 V2 is significantly more affordable at C$25.90, making it an attractive option for budget-conscious consumers. In contrast, the Peerless Assassin 120 SE V2, priced at C$54.90, offers advanced features and superior performance that justify its higher cost. Users must consider whether the additional investment in the Peerless model aligns with their cooling needs and system requirements, particularly in scenarios requiring extensive CPU performance.
Which should you buy?
Choosing between the Thermalright Assassin X 120 V2 Plus and the Peerless Assassin 120 SE V2 ultimately depends on your cooling needs and budget. If you require a budget-friendly option for average workloads and appreciate compact designs, the Assassin X 120 V2 might be the right fit. However, if you are looking for exceptional cooling performance, especially for high-demand applications or overclocking, the Peerless Assassin 120 SE V2’s superior features and build quality make it a worthwhile investment.
