Overview of the Products

The Thermalright TL-C12C-S CPU Fan and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler are two notable offerings from the reputable brand Thermalright, catering to different cooling needs. The TL-C12C-S is priced at £15.90, making it an economical choice for users seeking efficient cooling solutions. On the other hand, the Peerless Assassin is available for £28.79, positioning it as a more premium option, aimed at delivering superior performance and enhanced features.

Performance Comparison

In terms of performance, both products showcase impressive specifications suitable for different setups. The TL-C12C-S operates at a maximum speed of 1500 RPM, achieving an airflow of 66.17 CFM while maintaining a noise level of just 25.6 dBA. This makes it a quiet yet effective cooling solution for cases and CPU coolers. Conversely, the Peerless Assassin also features two PWM fans with the same speed and airflow characteristics, but it is designed to provide enhanced cooling performance thanks to its advanced cooling technologies, including six heat pipes. This dual-fan setup suggests that the Peerless Assassin may offer better thermal management under heavy loads.

Design and Aesthetics

When it comes to design, both coolers feature ARGB lighting, but they do so in different capacities. The TL-C12C-S boasts a single fan with up to 17 modes of light effects that can be synchronised through a motherboard port. This allows for customisation and integration into a gaming or high-performance build. In contrast, the Peerless Assassin, equipped with two fans, enhances the ARGB experience with more vibrant and dynamic lighting effects, ensuring it stands out in any rig. The aesthetic appeal of both products is notable, but the Peerless Assassin’s dual-fan design provides a more visually striking appearance.

Installation and Compatibility

The installation process and compatibility are crucial factors in selecting a cooler. The TL-C12C-S is designed as a versatile fan that can be used both as a case fan and in conjunction with CPU coolers, making it a flexible option for various configurations. In contrast, the Peerless Assassin is specifically engineered for CPUs, supporting a wide range of socket types, including Intel's 115X/1200/1700 and AMD's AM4/AM5. Its design includes metal fasteners for secure installation, which may simplify the setup process for users looking to maximise their cooling performance.

Noise Levels

Noise levels are an essential consideration for many PC builders, particularly for those who prefer a quieter environment. Both the TL-C12C-S and the Peerless Assassin maintain a noise level of 25.6 dBA, making them relatively quiet options in the realm of CPU cooling solutions. However, the TL-C12C-S achieves this noise level with a single fan, whereas the Peerless Assassin accomplishes it with a dual-fan setup, which may suggest that it can provide powerful cooling without excessive noise, particularly under load.

Build Quality and Durability

Build quality is critical for longevity, and both products exhibit high standards. The TL-C12C-S utilises S-FDB bearings that minimise blade shaking and reduce noise, thereby extending the fan's lifespan. The Peerless Assassin, on the other hand, employs six pure copper sintered heat pipes along with a full electroplating reflow welding process, indicating a robust construction aimed at optimal heat dissipation. This suggests that while both products are built to last, the Peerless Assassin may offer a slight edge in terms of durability, especially under heavy operational conditions.

Price Consideration

Price is a decisive factor for many consumers. The TL-C12C-S is priced at £15.90, catering to budget-conscious users who still desire quality cooling performance. Conversely, the Peerless Assassin is slightly more expensive at £28.79, reflecting its advanced features and dual-fan design. While the TL-C12C-S provides excellent value for its price, the additional investment in the Peerless Assassin may be justified for those seeking superior cooling capabilities and aesthetics.

Which should you buy?

Choosing between the Thermalright TL-C12C-S CPU Fan and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific needs and budget. If you’re looking for an economical and versatile cooling solution that performs well in various setups, the TL-C12C-S is an excellent choice at £15.90. However, if you require enhanced cooling performance, aesthetic appeal, and robust build quality, the Peerless Assassin, priced at £28.79, is likely the better investment. Both products are high-quality offerings from Thermalright, but your choice should align with your cooling requirements and budget preferences.
