Overview of Thermalright Peerless Assassin 120 Black
The Thermalright Peerless Assassin 120 Black CPU Air Cooler is priced at $38.90 and is designed for effective heat dissipation with its unique features. It boasts 6 heat pipes and is equipped with dual PWM fans, which contribute to its cooling efficiency. The cooler's dimensions are 125mm x 135mm x 157mm, making it a substantial choice for gamers and performance enthusiasts looking for a reliable air cooler.
This cooler employs AGHP technology, which enhances its heat transfer capabilities, allowing it to handle a thermal design power (TDP) of up to 245W. The combination of aluminum construction and a pure copper base ensures optimal thermal conductivity, making it a solid option for various Intel and AMD socket platforms.
Overview of Thermalright PS120SE
The Thermalright PS120SE CPU Air Cooler comes in at a slightly lower price of $35.90, making it about 3% cheaper than the Peerless Assassin. This cooler features 7 heat pipes, which provide enhanced cooling performance compared to its counterpart. With dimensions of 125mm x 135mm x 154mm, it is slightly shorter than the Peerless Assassin but still retains a robust design suitable for high-performance computing.
The PS120SE also utilizes AGHP technology, but it boasts the upgraded 4th generation version, allowing for better efficiency and a TDP range of 105W to 280W. The use of S-FDB bearings enhances the fan's lifespan, ensuring that the cooler remains effective over time. This model is compatible with a wide variety of CPU sockets, making it versatile for different setups.
Cooling Performance
Cooling performance is a critical factor for any CPU cooler, and the Thermalright Peerless Assassin 120 Black excels with its dual 120mm TL-C12B PWM fans. These fans can achieve a maximum airflow of 66.17 CFM and operate at a noise level of just 25.6 dB(A) at 1500 RPM. The 6 heat pipes work synergistically to manage heat effectively, making it ideal for high-performance CPUs.
Conversely, the Thermalright PS120SE also features dual TL-C12B V2 PWM fans that offer similar specifications in terms of airflow and noise levels. However, with 7 heat pipes, it has a slight edge in potential cooling performance, particularly for CPUs with higher TDPs. The combination of effective airflow and additional heat pipes makes the PS120SE an excellent contender for users prioritizing cooling efficiency.
Build Quality and Design
Both coolers are built with quality materials, featuring aluminum heatsinks and a copper base. The Thermalright Peerless Assassin has a robust design highlighted by its aluminum heatsink cover and an offset asymmetric layout that allows for easy installation without obstructing first PCIe slots. Its dimensions make it a visually appealing option as well.
On the other hand, the Thermalright PS120SE has a refined look with an anodized black frosted top and finely carved pure copper base. This cooler's design not only enhances aesthetics but also maximizes the heat dissipation area. The choice of materials and design in both models exemplifies Thermalright’s commitment to quality, though the PS120SE has a more modern appearance with its sleek finish.
Compatibility
Compatibility is essential when choosing a CPU cooler, and both the Thermalright Peerless Assassin 120 Black and the PS120SE excel in this regard. The Peerless Assassin supports a wide range of Intel sockets, including LGA 1700, 115X, and AMD AM4/AM5. This extensive compatibility means it can fit various builds and setups.
Similarly, the PS120SE also supports a broad range of Intel and AMD sockets, including LGA 1700 and AM4/AM5. The inclusion of corresponding mounting plates for different CPU socket platforms ensures that users can easily install either cooler without compatibility issues. Therefore, both models cater well to users with varying hardware configurations.
Noise Levels
Noise levels are a significant consideration for users who want a quiet computing environment. Both the Thermalright Peerless Assassin and the PS120SE operate at a maximum noise level of 25.6 dB(A). This level is relatively quiet, ensuring that neither cooler will disrupt a standard computing or gaming environment.
The dual fans in both coolers are designed to deliver optimal performance without generating excessive noise, making them suitable for users who prioritize a quieter operation. Given that both models produce the same noise level, the choice here may come down to other factors such as pricing or specific cooling performance.
Price Comparison
The price difference between the Thermalright Peerless Assassin 120 Black and the PS120SE is minimal, with the former priced at $38.90 and the latter at $35.90. This represents a difference of $3, making the PS120SE about 8% cheaper. For budget-conscious buyers, this small price reduction could be a deciding factor, especially considering the cooling performance advantages of the PS120SE’s additional heat pipe.
However, the slight premium for the Peerless Assassin may be justified by its higher TDP capacity, which could appeal more to users with high-performance CPUs. Therefore, while both options are competitively priced, the choice may ultimately depend on specific performance needs and budget constraints.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 Black and the PS120SE ultimately comes down to your specific needs and preferences. If you are looking for a cooler with a higher TDP capacity and a slightly more robust design, the Peerless Assassin may be the better choice despite its higher price. On the other hand, if you prioritize a quieter operation with a lower price point and slightly enhanced cooling performance, the PS120SE stands out as the more cost-effective option. Both coolers are excellent choices, but understanding your cooling requirements and budget will help you make the best decision.
