Introduction to CPU Coolers

When choosing a CPU cooler, two options from Thermalright stand out: the Thermalright Peerless Assassin 140 Black CPU Cooler and the Thermalright PS120SE CPU Air Cooler. Both products are designed to efficiently dissipate heat from your CPU, but they cater to different needs and preferences. The Peerless Assassin is priced at C$54.90, while the PS120SE is more budget-friendly at C$44.90. This article will delve into various aspects of each cooler to help you make an informed decision.

Design and Build Quality

The Thermalright Peerless Assassin features a twin-tower body with symmetrical mecha-shaped fins, complemented by a pure copper base and six heatpipes. This design allows for better heat dissipation, making it suitable for larger chassis and high-performance components. With a height of 158mm, it excels in maximizing cooling capacity.

In contrast, the Thermalright PS120SE has a slightly more compact design, measuring 125mm x 135mm x 154mm. It employs a single tower configuration and features a sophisticated AGHP technique for heat transfer. Both coolers are constructed from aluminium, but the PS120SE's anodized black frosted top gives it a sleek look. The choice here largely depends on your case size and aesthetic preference.

Cooling Performance

Cooling performance is crucial for any CPU cooler, and both the Peerless Assassin and the PS120SE deliver impressive results. The Peerless Assassin boasts dual PWM fans that can reach speeds of 1500 RPM and generate an air volume of up to 66.17 CFM. This configuration is designed for maximum heat dissipation, making it ideal for high-performance CPUs.

Meanwhile, the PS120SE also features a PWM fan with similar specifications, including a maximum speed of 1500 RPM and an air volume of 66.17 CFM. Both coolers operate at a noise level of ≤25.6 dB(A), ensuring that they provide efficient cooling without excessive noise. The Peerless Assassin's dual-fan design may give it an edge in cooling capacity, especially under heavy loads.

Compatibility

Compatibility is a significant factor when selecting a CPU cooler. The Thermalright Peerless Assassin supports a wide range of CPU socket types, including Intel's LGA1150 through LGA1851 and AMD's AM4 and AM5. This broad compatibility makes it suitable for a variety of builds, from older systems to the latest processors.

On the other hand, the Thermalright PS120SE also supports several CPU sockets, including Intel’s LGA1700, LGA1150, and AMD’s AM4 and AM5. While both coolers offer similar compatibility, the Peerless Assassin's wider range of supported Intel sockets may be beneficial for users with older systems.

Installation Process

The installation process can greatly influence user experience, and both coolers have been designed with ease of installation in mind. The Peerless Assassin comes with all-metal fasteners and an SS2 buckle system, which simplifies the mounting process. Its dual-tower design, however, may require a bit more space during installation.

In contrast, the PS120SE is similarly equipped with a mounting kit that includes the appropriate plates and fasteners for various CPU sockets. Its slightly smaller footprint could make installation easier, especially in tighter cases. Both options provide adequate installation support, but the Peerless Assassin might be more challenging due to its size.

Price and Value

When it comes to pricing, the Thermalright PS120SE is more budget-friendly at C$44.90, compared to the Peerless Assassin's C$54.90. For users looking for a reliable cooler without breaking the bank, the PS120SE presents a compelling option. However, the Peerless Assassin offers advanced features, such as dual fans and superior cooling potential, which may justify the additional cost for enthusiasts.

Both coolers provide good value for their respective price points, but the final decision may depend on whether you prioritize budget or enhanced cooling performance.

Brand Reputation and Support

Thermalright has a strong reputation in the cooling market, with over 20 years of experience. Both the Peerless Assassin and PS120SE are backed by the brand's commitment to quality and performance. Customers can expect reliable support for both products, ensuring peace of mind when making a purchase.

While customer reviews and feedback can vary, Thermalright's long-standing presence in the industry lends credibility to both coolers. Users can feel confident in their choice, knowing that they are investing in a product from a reputable manufacturer.

Which should you buy?

Deciding between the Thermalright Peerless Assassin 140 Black CPU Cooler and the Thermalright PS120SE CPU Air Cooler ultimately comes down to your specific needs and budget. If you require maximum cooling performance and have the space to accommodate its larger design, the Peerless Assassin is the superior choice. However, if you are looking for a more affordable option that still offers excellent cooling capabilities, the PS120SE is an excellent value. Both coolers excel in performance, compatibility, and design, making them solid contenders in the CPU cooler market.
