Overview of the Thermalright Peerless Assassin 120 SE and Burst Assassin 120 SE ARGB
The Thermalright Peerless Assassin 120 SE is priced at C$48.90, while the Thermalright Burst Assassin 120 SE ARGB comes in at a more budget-friendly C$29.90. Both products bring quality cooling solutions to the table, but they cater to different needs and price points. Understanding the key differences can help you decide which cooler is the right fit for your system.
Design and Build Quality
The Thermalright Peerless Assassin 120 SE features a dual tower heatsink configuration, measuring 125(L)x135(W)x155(H)mm. This design not only provides better heat exchange surface area but also incorporates high-performance ARGB lighting effects through its two fans. In contrast, the Burst Assassin 120 SE utilises a single tower design, which can be more space-efficient but may not dissipate heat as effectively under heavy loads. Both coolers are designed for compatibility with a variety of CPU sockets, ensuring broad usability for different builds.
Cooling Performance
In terms of cooling performance, both coolers are equipped with 120mm PWM fans that can reach a speed of 1550 RPM. However, the Peerless Assassin has a dual fan setup, potentially offering superior airflow and heat dissipation with a rated air flow of 66.17 CFM, compared to the single fan of the Burst Assassin. This difference in fan configuration could make the Peerless a better choice for overclocking or high-performance systems where heat management is critical.
Noise Levels
Both the Peerless Assassin and Burst Assassin maintain a similar noise level, rated at ≤25.6 dB(A). This means that both coolers can operate quietly, making them suitable for builds where noise is a concern. However, the dual fan design of the Peerless Assassin may result in more efficient cooling at lower RPMs, which could lead to quieter operation during regular use compared to the Burst Assassin under load.
Installation and Compatibility
Both coolers offer a straightforward installation process, supporting a wide range of Intel and AMD sockets, including the latest AM5 and LGA1700. The Peerless Assassin requires the use of the motherboard's built-in backplate for AMD installations, while the Burst Assassin also provides necessary mounting hardware. The Burst Assassin's fin offset technology allows for no memory height limitations, which can be a significant consideration in cramped cases, making it potentially easier to integrate into diverse builds.
Aesthetic Appeal
When it comes to aesthetics, both coolers feature ARGB lighting, but the Peerless Assassin stands out with its two high-performance ARGB fans that deliver vibrant lighting effects. This can enhance the visual appeal of your build, especially for users who prioritise aesthetics alongside performance. The Burst Assassin, while still visually appealing, may lack the same level of brightness and dynamic lighting options offered by its counterpart.
Durability and Longevity
Regarding durability, both coolers are designed with high-quality materials. The Peerless Assassin is equipped with copper heat pipes and features AGHP technology that improves heat exchange efficiency. Similarly, the Burst Assassin utilises nickel-plated copper heat pipes and S-FDB bearings, which are known for their long service life. Both coolers are constructed to withstand prolonged usage, making them reliable options for gamers and PC enthusiasts.
Price and Value
The Thermalright Peerless Assassin 120 SE is priced at C$48.90, while the Burst Assassin is significantly more affordable at C$29.90. If budget is a primary concern, the Burst Assassin offers excellent value without sacrificing essential features. However, for those willing to invest more for potentially better cooling performance and build quality, the Peerless Assassin may justify its higher cost.
Which should you buy?
Choosing between the Thermalright Peerless Assassin 120 SE and the Burst Assassin 120 SE ARGB ultimately depends on your specific needs and budget. If you prioritise cooling performance, aesthetics, and have a bit more to spend, the Peerless Assassin may be the better option. However, if you're looking for an effective cooler at a lower price point and value ease of installation, the Burst Assassin stands out as a solid choice. Both options bring quality and reliability, so you can’t go wrong with either.
