Overview of the Products

In this comparison, we will examine the Thermalright TL-M12QR-S X3 Wireless Splicing Reverse Case Fan and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler. The TL-M12QR-S is priced at £20.59, while the Peerless Assassin costs £28.79. Both products come from Thermalright, a brand known for its focus on computer cooling solutions. Here, we will evaluate their features, performance, and suitability for different cooling needs.

Design and Aesthetics

The TL-M12QR-S features a modern design with an ARGB infinite mirror effect, incorporating a segmented light design that enhances the aesthetic appeal of any gaming rig. The soft silicone corner pads contribute to its silent operation, which is capped at 23.2 decibels. In contrast, the Peerless Assassin presents a more robust structure with dual tower cooling, emphasising functionality over flashiness. It also includes colourful ARGB lighting that can enhance the visual appeal of a build. The difference in design philosophy indicates that while the TL-M12QR-S targets users looking for quiet performance with stylish lighting, the Peerless Assassin appeals to those prioritising cooling efficiency alongside decent aesthetics.

Performance and Cooling Efficiency

When it comes to air flow, the TL-M12QR-S delivers an impressive 47.6 CFM at a maximum speed of 1500 RPM, making it suitable for maintaining lower temperatures in a range of setups. The Peerless Assassin, however, outperforms it with a maximum air flow of 66.17 CFM, also at 1500 RPM. This higher air flow rating suggests superior cooling capabilities, which is critical for high-performance CPUs under load. The TL-M12QR-S focuses on silent operation with a noise level of ≤23.2 dB, while the Peerless Assassin operates at a slightly higher noise level of ≤25.6 dB. This indicates that while both products are designed for quiet performance, the Peerless Assassin may generate a bit more sound during operation.

Installation and Compatibility

The TL-M12QR-S is designed with a wireless splicing feature that reduces internal cable complexity, making installation straightforward. It is powered via a 4-pin PWM connection and requires a 5V 3-pin lighting interface. The Peerless Assassin, on the other hand, supports various CPU sockets including Intel's 115X/1200/1700 and AMD's AM4/AM5, making it highly versatile for different system builds. The inclusion of both Intel and AMD mounting hardware further simplifies installation for users. Thus, if compatibility across multiple platforms is a priority, the Peerless Assassin clearly has the advantage.

Noise Levels and Silent Operation

Noise levels are a significant factor for many users when choosing cooling solutions. The TL-M12QR-S operates at a remarkably low noise level of ≤23.2 dB, making it one of the quieter options available. This makes it an excellent choice for those who prefer a nearly silent computing environment, such as gamers or professionals working on noise-sensitive tasks. In comparison, the Peerless Assassin, while still relatively quiet at ≤25.6 dB, is slightly noisier. For users who prioritise silence above all, the TL-M12QR-S may be the better choice, but the difference in noise levels is marginal.

Build Quality and Materials

Both products showcase Thermalright's commitment to quality. The TL-M12QR-S utilises a 7-blade design that optimises air flow while maintaining lower noise levels. The Peerless Assassin features 6 heat pipes and a pure copper base designed to enhance heat dissipation. Additionally, its dual tower design is built for maximum cooling efficiency, indicating a more robust construction aimed at high-performance systems. While the TL-M12QR-S excels in silent operation, the Peerless Assassin's build quality is tailored for users needing reliable cooling for intensive tasks, such as gaming or content creation.

Price and Value for Money

With the TL-M12QR-S priced at £20.59 and the Peerless Assassin at £28.79, the difference in price reflects the varying functionalities of each product. The TL-M12QR-S offers excellent value for users seeking a stylish and quiet cooling solution at a budget-friendly price. Conversely, the Peerless Assassin, while more expensive, provides enhanced cooling performance and broader compatibility, making it worth the investment for gamers and high-performance users. Therefore, depending on your specific needs, one may offer better value than the other.

User Experience and Feedback

Feedback for the TL-M12QR-S generally highlights its quiet operation and attractive lighting effects, making it a popular choice for users who prioritise aesthetics and noise reduction. The Peerless Assassin, however, receives praise for its effective cooling performance and reliability under load. Users often mention that while it is slightly noisier, the cooling efficiency justifies the sound. Ultimately, user experience can vary based on individual needs, with the TL-M12QR-S favouring aesthetics and silence, while the Peerless Assassin leans towards performance and versatility.

Which should you buy?

Choosing between the Thermalright TL-M12QR-S X3 Wireless Splicing Reverse Case Fan and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific requirements. If you are looking for a quiet operation with stylish lighting effects and a more budget-friendly price, the TL-M12QR-S is the ideal choice. However, if you need superior cooling performance and compatibility with a variety of CPU sockets, the Peerless Assassin justifies its higher price with its efficiency and build quality. Consider your priorities carefully to make the best decision for your cooling needs.
