Dimension comparison
Overview of the Products
The Thermalright TL-C12CW-S X3 CPU Fan and the Thermalright Peerless Assassin 120 Black CPU Air Cooler are both designed to enhance cooling in PC builds, but they serve different purposes. The TL-C12CW-S X3 is a 120mm case cooler fan priced at C$17.99, while the Peerless Assassin 120 is a more robust CPU cooler priced at C$54.90. Choosing between these products depends on your specific cooling needs and system compatibility.
Cooling Performance
When it comes to cooling performance, the Peerless Assassin 120 has a distinct advantage. It features a dual-tower design with an effective heat dissipation area of 9600cm, which is specifically engineered for CPU cooling. The TL-C12CW-S X3 operates at a maximum speed of 1550 RPM and offers an airflow of 66.17 CFM, making it suitable for case ventilation. However, it lacks the dedicated heat dissipation capability of the Peerless Assassin, which incorporates six heat pipes designed for optimal CPU cooling.
Design and Aesthetics
The TL-C12CW-S X3 boasts an appealing design with high-brightness LED atomizing ARGB fan blades, offering up to 17 lighting modes for a visually striking setup. In contrast, the Peerless Assassin 120 features a sleek black design with a nanoscale electroplating finish. Its aesthetic is more understated, focusing on functionality rather than flashy visuals. Therefore, if you prioritise aesthetics, the TL-C12CW-S X3 is likely the better choice, while the Peerless Assassin appeals to those who prefer a more subdued look.
Noise Levels
In terms of noise output, both products maintain a low level of operational noise. The TL-C12CW-S X3 operates at a noise level of 25.6 dBA, which is quite silent for a fan of its size and capabilities. The Peerless Assassin 120 matches this with a similar noise level of 25.6 dB(A) for its fans. This means that both products will provide effective cooling without being disruptive, making either a suitable option for quiet PC builds.
Installation and Compatibility
The installation process and compatibility are crucial factors for any cooling solution. The TL-C12CW-S X3 is designed for universal case use and is compatible with a variety of setups thanks to its 4-pin PWM connector. On the other hand, the Peerless Assassin 120 is engineered to fit a broader range of CPU sockets, supporting both Intel and AMD platforms, including LGA1700 and AM5. This makes the Peerless Assassin a versatile choice for users looking to upgrade their CPU cooling without worrying about compatibility issues.
Build Quality
Build quality is a significant consideration for longevity and performance. The TL-C12CW-S X3 utilises high-quality S-FDB bearings, which are designed to minimise noise and extend the fan's lifespan. The Peerless Assassin 120 features a more complex construction, including a dual-tower design and six pure copper heat pipes, which enhance its cooling efficiency. The materials used in both products ensure durability, but the Peerless Assassin’s construction is tailored for superior heat management.
Price Considerations
Price is an important factor when deciding between the two products. The TL-C12CW-S X3 is priced at a more budget-friendly C$17.99, making it an excellent option for users seeking a cost-effective solution for case cooling. In contrast, the Peerless Assassin 120 is priced at C$54.90, which reflects its advanced cooling capabilities and dual-fan design. While the initial investment is higher, the performance benefits may justify the cost for gamers and professionals with demanding cooling needs.
Which should you buy?
Choosing between the Thermalright TL-C12CW-S X3 CPU Fan and the Thermalright Peerless Assassin 120 Black CPU Air Cooler ultimately comes down to your specific needs. If you are looking for an aesthetically pleasing case fan with effective airflow for general cooling, the TL-C12CW-S X3 is a solid choice at a budget-friendly price. However, if you need superior CPU cooling performance and compatibility with multiple socket types, the Peerless Assassin 120 is the better investment, despite the higher price tag. Consider your system requirements and budget to make the most informed decision.
