Dimension comparison
Overview
In this comparison, we will examine two CPU coolers from Thermalright: the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler. With prices of C$32.90 and C$54.90 respectively, these coolers target users seeking effective thermal management for their CPUs. While both products boast solid performance and compatibility, their differing features and specifications make them suited for various user needs and preferences.
Design and Dimensions
The Thermalright Assassin X 120R features a compact design, measuring 120x71x151mm, while the Peerless Assassin 120 SE V2 is slightly larger at 125x135x155mm. The Assassin X 120R is designed with symmetrical all-aluminum fins that enhance its aesthetic appeal, particularly with its digital ARGB lighting, which can synchronise with a motherboard's 5V 3-pin connector. In contrast, the Peerless Assassin 120 SE V2 uses a combination of aluminum fins and a copper base, promising better thermal conductivity. Both coolers are compatible with popular Intel and AMD sockets, making them versatile choices for various systems.
Cooling Performance
When it comes to cooling performance, the Peerless Assassin 120 SE V2 takes the lead with an impressive airflow rating of 88.19 CFM, compared to the Assassin X 120R's 70.84 CFM. The Peerless also has a TDP rating of up to 265 watts, indicating its capacity to handle more powerful CPUs. Meanwhile, the Assassin X 120R operates at a maximum fan speed of 2000 RPM, which, combined with its effective heat sink design, allows it to maintain a low operating noise level of 29.8 dB(A). Overall, while both coolers provide adequate cooling, the Peerless Assassin 120 SE V2 offers superior airflow and thermal handling capabilities.
Fan Specifications
The fans used in these coolers also differ significantly. The Assassin X 120R employs a 120x120x25mm PWM fan, which operates at a speed of 2000 RPM. This fan is designed to provide a balance between airflow and noise, with a maximum noise level of 29.8 dB(A). Conversely, the Peerless Assassin 120 SE V2 features dual 120x120x28mm PWM fans that operate at a slightly lower maximum speed of 1850 RPM. However, the additional fan contributes to its higher airflow rating. This factor may be crucial for users who prioritise cooling performance over noise levels.
Noise Levels
Noise levels are an important consideration for many users, especially those who prefer a quieter computing environment. The Assassin X 120R operates at a maximum noise level of 29.8 dB(A), while the Peerless Assassin 120 SE V2 is marginally quieter at 29.5 dB(A). Despite the slight difference, both coolers are relatively quiet during operation, making them suitable for both gaming and professional setups. Users looking for minimal noise will find either option acceptable, but the Peerless offers a marginal edge in silence.
Compatibility
Both coolers boast excellent compatibility with a wide range of CPU sockets. The Assassin X 120R supports Intel LGA 1851, 1700, 1150, 1151, 1155, 1156, and 1200, along with AMD AM4 and AM5 sockets. The Peerless Assassin 120 SE V2 matches this compatibility, supporting the same Intel and AMD sockets. This broad compatibility ensures that users can install either cooler on most modern CPUs without difficulty. The inclusion of installation accessories and detailed installation instructions further enhances the usability of both products.
Pricing and Value
The Thermalright Assassin X 120R is currently priced at C$32.90, making it an attractive option for budget-conscious consumers looking for effective cooling without breaking the bank. In comparison, the Peerless Assassin 120 SE V2 is priced higher at C$54.90. While the Peerless offers advanced features and superior cooling performance, the higher price point may deter some users. Ultimately, the value of each cooler will depend on individual needs—those seeking aesthetic appeal and decent performance might prefer the Assassin X 120R, while users demanding maximum cooling efficiency might justify the investment in the Peerless.
Which should you buy?
Choosing between the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler ultimately depends on your specific needs and budget. If aesthetics and a lower price point are your priorities, the Assassin X 120R offers solid performance and eye-catching ARGB features for C$32.90. However, if you require superior cooling performance and don't mind spending an additional C$22.00, the Peerless Assassin 120 SE V2 stands out with its higher airflow and dual fan design. Assess your cooling demands, system compatibility, and budget to make the best choice for your setup.
