Introduction to CPU Air Coolers
When it comes to keeping your CPU cool, selecting the right air cooler is crucial for optimal performance. In this comparison, we will take a closer look at two popular options from Thermalright: the Thermalright PS120SE CPU Air Cooler and the Thermalright Peerless Assassin 120 Black CPU Air Cooler. Both coolers boast impressive features, but they cater to different cooling needs and preferences.
Pricing Comparison
The Thermalright PS120SE is priced at C$44.90, making it a more budget-friendly option. In contrast, the Thermalright Peerless Assassin 120 Black is available for C$54.90, reflecting a higher investment for potentially enhanced cooling capabilities. This C$10 difference might influence users on a tighter budget, but it’s essential to consider what features come with the higher price tag of the Peerless Assassin.
Cooling Performance
The Thermalright PS120SE supports a thermal design power (TDP) range of 105W to 280W, making it suitable for a variety of CPUs. Its advanced AGHP technique utilizes a 7x6mm heatpipe, aiming to deliver efficient cooling. On the other hand, the Thermalright Peerless Assassin 120 Black features a more extensive effective heat dissipation area of 9600cm, attributed to its twin-tower design. This gives it an edge in heat dissipation, particularly under heavy loads, making it better suited for overclocking scenarios.
Design and Build Quality
In terms of design, both coolers exhibit robust construction. The Thermalright PS120SE features an anodized black frosted top with a finely carved pure copper base, ensuring effective heat transfer. It measures 125(L)x135(W)x154(H)mm and weighs 0.9kg. In contrast, the Peerless Assassin stands slightly taller at 157mm and weighs 1.02kg. Its dual-tower design with a full electroplating reflow welding process not only enhances its aesthetics but also its structural integrity, making it a visually appealing choice for those who care about the look of their build.
Fan Efficiency
Both products are equipped with PWM fans that maintain a noise level of ≤25.6dB(A) while operating at a fan speed of 1500rpm. However, the Thermalright Peerless Assassin 120 Black comes with two PWM fans, which collectively contribute to better airflow and cooling performance. With a maximum airflow of 66.17CFM, the dual-fan setup is advantageous for users seeking enhanced cooling efficiency, especially in high-performance environments where heat generation is significant.
Compatibility and Installation
Compatibility is an important factor to consider, and both coolers support a wide range of CPU sockets. The Thermalright PS120SE is compatible with Intel sockets LGA1700, 1851, 1150, 1151, 1155, 1156, and 1200, as well as AMD's AM4 and AM5. The Peerless Assassin supports an even broader range, including LGA1150, 1151, 1155, 1156, 1200, 1700, 17XX, 2066, and 2011, along with the same AMD sockets. This versatility makes the Peerless Assassin a more flexible option for users with diverse setups.
Noise Levels
Both the Thermalright PS120SE and the Thermalright Peerless Assassin 120 Black operate at a similar noise level of ≤25.6dB(A), which is ideal for users who prioritize low-noise operation in their systems. This means that regardless of which cooler you choose, you can expect a quiet computing experience. However, the Peerless Assassin's dual fans might produce a more pronounced sound under heavy load, although this should still remain within acceptable limits.
User Experience
User experience is often influenced by installation ease and performance reliability. The Thermalright PS120SE is designed to be compatible with various CPU platforms, offering the necessary mounting plates or fasteners for a straightforward installation process. The Peerless Assassin, with its twin towers and dual fans, may require a bit more space and attention during installation but provides superior cooling performance once set up. Users looking for a straightforward cooler might prefer the PS120SE, while those seeking the best cooling performance might lean towards the Peerless Assassin.
Which should you buy?
Ultimately, the choice between the Thermalright PS120SE CPU Air Cooler and the Thermalright Peerless Assassin 120 Black CPU Air Cooler hinges on your specific needs and budget. If you're looking for a more affordable option that still provides reliable cooling performance, the PS120SE at C$44.90 is a solid choice. However, if you're willing to invest a bit more for enhanced cooling capabilities and a dual-fan setup, the Peerless Assassin at C$54.90 could be the better option, particularly for high-performance builds or overclocking scenarios. Assess your cooling requirements and budget to make the most informed decision.
