Price Comparison

When considering the price, the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler is slightly more expensive at £28.79 compared to the Thermalright TL-M12Q-S X3 120mm PC Case Fans, which retails for £25.90. While the difference of £2.89 may seem minimal, it could influence your decision based on your budget. The TL-M12Q-S offers a pack of three fans for this price, which may provide better value for those looking to enhance airflow throughout their PC case. In contrast, the Peerless Assassin is a single CPU air cooler that focuses on cooling performance rather than multiple units.

Cooling Performance

The Thermalright TL-M12Q-S fans boast a maximum airflow of 68.9 CFM and a noise level of 28.2 dBA, making them efficient at cooling while maintaining a relatively quiet operation. On the other hand, the Peerless Assassin offers a slightly lower maximum airflow of 66.17 CFM but operates at an even quieter level of 25.6 dBA. While both products aim to keep your system cool, the TL-M12Q-S fans may excel in scenarios where maximum airflow is essential, while the Peerless Assassin prioritises a quieter operation, which may be preferable in noise-sensitive environments.

Design and Aesthetics

In terms of aesthetics, the Thermalright TL-M12Q-S features a unique ARGB mirror lighting effect, creating a visually striking appearance with its infinite frame structure. This design is complemented by multiple colourful lighting effects that can be synchronised with the airflow. Conversely, the Peerless Assassin also incorporates ARGB lighting but focuses more on a robust cooling design with its double tower setup. While the TL-M12Q-S may appeal to those looking for impressive visual effects, the Peerless Assassin prioritises functionality with a sleek look that fits well in various build styles.

Installation and Compatibility

The installation process differs significantly between the two products. The TL-M12Q-S fans simplify cable management through a single cable connection per fan cluster, which can ease installation and reduce clutter. Additionally, these fans can be used not only as case fans but also in conjunction with a CPU cooler for enhanced cooling performance. In contrast, the Peerless Assassin comes with dedicated mounting hardware for both Intel and AMD platforms, making it versatile for different CPU sockets. Its design allows for unrestricted installation concerning RAM clearance, which may be crucial for builds with taller memory modules.

Features and Technology

The features of the Thermalright TL-M12Q-S include quality S-FDB bearings that minimise noise while maximising cooling efficiency. It operates at a maximum speed of 2000 RPM, ensuring robust airflow when needed. The Peerless Assassin, meanwhile, employs six 6mm heat pipes with AGHP technology to combat the inverse gravity effect, ensuring effective thermal dissipation in both vertical and horizontal orientations. Its design also includes dual PWM fans that can adjust their speed based on temperature, allowing for more responsive cooling. This technological distinction may cater to users who prioritise advanced cooling solutions.

Build Quality and Durability

Build quality is a critical factor in determining longevity and performance. The TL-M12Q-S fans feature S-FDB bearings, which are designed to extend the life of the fans while reducing operational noise. This focus on durability is essential for maintaining system stability over time. The Peerless Assassin, constructed with pure copper heat pipes and an aluminium heat sink, also emphasises durability and efficiency. Both products reflect Thermalright's commitment to quality, but the choice may boil down to whether you value fan longevity or the cooler's robustness.

User Experience and Noise Levels

User experience can vary significantly based on the noise levels produced by these products. The TL-M12Q-S fans operate at a maximum noise level of 28.2 dBA, which may be noticeable in a quiet room. In contrast, the Peerless Assassin operates at a quieter maximum of 25.6 dBA, making it a suitable option for users who prefer a silent system. The difference in noise levels highlights the TL-M12Q-S's airflow capabilities versus the Peerless Assassin's quieter performance, catering to different user preferences based on their environment.

Which should you buy?

Choosing between the Thermalright TL-M12Q-S X3 120mm PC Case Fans and the Thermalright Peerless Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific needs. If you require multiple fans for enhanced airflow and aesthetic appeal, the TL-M12Q-S offers excellent value at £25.90 with its ARGB lighting and simplified installation. However, if your focus is on a robust CPU cooler with quieter operation and advanced thermal management, the Peerless Assassin at £28.79 may be the better choice. Your decision should align with your priorities—whether it's cooling performance, noise levels, or design aesthetics.
