Overview of the Thermalright PS120SE and Peerless Assassin 120
The Thermalright PS120SE CPU Air Cooler is priced at C$44.90, while the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler comes in at C$52.62. Both coolers are designed to offer efficient cooling solutions but differ in their construction and cooling capabilities.
The PS120SE features a single tower design with a 120mm fan, while the Peerless Assassin boasts a dual-tower configuration with two 120mm fans. This fundamental difference in design plays a significant role in their cooling performance and suitability for different CPU setups.
Cooling Performance
When it comes to cooling performance, the Thermalright Peerless Assassin stands out with its dual-fan setup and a maximum airflow of 88.89 CFM at a fan speed of 1850 RPM. This enhances its ability to dissipate heat effectively, especially during intense gaming or heavy workloads.
In contrast, the PS120SE offers a maximum airflow of 66.17 CFM, with its single fan operating at a speed of 1500 RPM. While it is still an efficient cooler, it may not perform as well under high thermal loads compared to the Peerless Assassin, making the latter the better choice for overclockers or high-performance users.
Noise Levels
Both coolers operate at a noise level of up to 25.6 dB(A), which is quite reasonable and suitable for most users who prefer a quieter computing environment.
However, the Peerless Assassin's dual fans may produce slightly more noise when running at higher speeds than the single fan of the PS120SE. The PS120SE's design and lower fan speed could be more appealing for users prioritizing silence over peak performance, but the difference is minimal, and both are relatively quiet under normal operating conditions.
Build Quality
The Thermalright PS120SE is constructed with an anodized black frosted top and a finely carved pure copper base, combined with aluminum fins that enhance heat dissipation. Its robust build ensures a long service life of up to 20,000 hours, making it a durable option for users.
On the other hand, the Peerless Assassin also features high-quality materials, including six pure copper heat pipes and a magnetic top cover. This attention to detail not only improves thermal conductivity but also adds to the overall aesthetic appeal with its ARGB lighting. Both coolers exhibit excellent build quality, but the Peerless Assassin offers a more modern design with visual customization options that might attract gamers and PC builders.
Compatibility
Both coolers are compatible with a wide range of CPU sockets, including Intel's LGA1700, LGA1851, LGA115x series, and AMD's AM4 and AM5 sockets. This versatility makes both options suitable for various builds, whether users are upgrading an existing system or building a new one.
The Peerless Assassin comes with dual-platform mounting clips, ensuring easy installation across different systems. Meanwhile, the PS120SE offers comprehensive compatibility as well, but its mounting process may be slightly less intuitive compared to the user-friendly design of the Peerless Assassin, which could be a deciding factor for less experienced builders.
Aesthetic Appeal
Aesthetic considerations can be crucial for PC builders, and here the Peerless Assassin takes the lead with its ARGB lighting effects. The dual fans feature customizable lighting that can be adjusted using the motherboard's built-in software, giving users the chance to personalize their setups visually.
In contrast, the PS120SE focuses more on functional design without any RGB lighting features. This makes it a more understated choice, appealing to users who prefer a cleaner look without flashy elements. The choice between these coolers may come down to individual preference regarding aesthetics.
Price Comparison
The Thermalright PS120SE is the more budget-friendly option at C$44.90, while the Peerless Assassin is priced at C$52.62. The price difference of C$7.72 can be justified by the additional features and enhanced cooling performance of the Peerless Assassin.
For users who are looking for basic CPU cooling without the need for advanced features, the PS120SE offers excellent value. However, for those seeking superior performance, especially in gaming or demanding applications, the investment in the Peerless Assassin may be worthwhile.
Which should you buy?
In conclusion, both the Thermalright PS120SE and the Thermalright Peerless Assassin 120 Digital ARGB Black CPU Air Cooler are solid choices within the CPU cooler market. The PS120SE is ideal for budget-conscious users who require reliable cooling without extra features, while the Peerless Assassin offers advanced cooling capabilities, aesthetic appeal, and a dual-fan setup for a slight premium.
Ultimately, if you prioritize cooling performance and visual customization, the Peerless Assassin is the better option. Conversely, if you are looking for a dependable cooler at a lower price, the PS120SE will meet your needs effectively.
