Overview of the Products
In this comparison, we will explore the Thermalright TL-M12Q-S X3 120mm PC Case Fans and the Thermalright Assassin X120 SE ARGB CPU Air Cooler. The TL-M12Q-S fans are priced at £25.90 for a pack of three, while the Assassin X120 SE cooler costs £16.29. Despite being from the same brand, these two products serve different purposes, making it essential to evaluate their features and benefits to determine which one suits your needs best.
Design and Build Quality
The design of the Thermalright TL-M12Q-S fans is characterised by their unique ARGB mirror lighting effect, which creates a visually stunning appearance with multiple colourful lighting options. Each fan measures 124mm in length, 120mm in width, and 25mm in height. On the other hand, the Thermalright Assassin X120 SE is a more robust CPU air cooler, measuring 120mm long, 71mm wide, and 148mm high. Both products showcase high-quality materials, but the cooler's aluminium heat sink and metal fasteners provide a sturdier build, essential for efficient cooling in a CPU setup. While the fans focus on aesthetics and airflow, the cooler prioritises structural integrity and compatibility with various CPU sockets.
Cooling Performance
When it comes to cooling performance, the Thermalright TL-M12Q-S fans boast an impressive airflow of 68.9 CFM at a maximum noise level of 28.2 dBA, making them effective for case ventilation. In contrast, the Assassin X120 SE cooler delivers slightly lower airflow at 66.17 CFM but operates at a quieter noise level of 25.6 dBA. The fans employ S-FDB bearings to minimise noise while maximising cooling efficiency, whereas the cooler utilises four heat pipes and also features S-FDB bearings, ensuring long-lasting performance. Both options provide excellent cooling capabilities, but the fans excel in case cooling, while the cooler is designed specifically for CPU temperature management.
Installation and Compatibility
The Thermalright TL-M12Q-S fans simplify installation with their straightforward cable management, requiring only one cable per fan cluster, which significantly reduces clutter. They come with a 4-pin PWM connector for automatic speed control based on motherboard temperature, making them user-friendly. In comparison, the Assassin X120 SE cooler is equipped with metal fasteners compatible with various Intel and AMD sockets, including LGA 1700 and AM5. This versatility allows for easy installation in a range of systems. While the fans are more adaptable for case cooling setups, the cooler’s compatibility is specifically tailored for CPU installations, making both products easy to integrate into your build.
Aesthetic Appeal
Aesthetic appeal is a strong point for the Thermalright TL-M12Q-S fans, thanks to their ARGB lighting effects that enhance the visual experience inside a PC case. The infinite frame structure allows for dynamic lighting effects that can be synchronised with the rest of the system. In contrast, the Assassin X120 SE cooler also features ARGB lighting, but its design is more utilitarian, focusing on performance rather than flashy aesthetics. While both products can enhance the overall look of a build, the TL-M12Q-S fans are the clear winner for those who prioritise vibrant lighting and visual flair.
Brand Reputation and Experience
Thermalright is a well-regarded brand with over 20 years of experience in the computer accessories market. Their dedication to research and development is evident in both the TL-M12Q-S fans and the Assassin X120 SE cooler. The brand has established a solid reputation for producing reliable and efficient cooling solutions, making them a favoured choice among PC enthusiasts. This experience adds value to both products, ensuring that consumers can trust in their performance and durability.
Price Comparison
The Thermalright TL-M12Q-S fans are priced at £25.90 for a pack of three, which translates to approximately £8.63 per fan. In comparison, the Assassin X120 SE cooler is priced at £16.29, making it a more affordable option for those looking for CPU cooling solutions. While the fans may seem more expensive upfront, they offer a complete set for improved case airflow. The cooler's lower price point positions it as an attractive option for users specifically seeking CPU cooling without the added aesthetic features of the fans. Ultimately, the choice may depend on your cooling needs and budget considerations.
Which should you buy?
Choosing between the Thermalright TL-M12Q-S X3 120mm PC Case Fans and the Thermalright Assassin X120 SE ARGB CPU Air Cooler ultimately depends on your specific cooling requirements. If you're looking for vibrant aesthetics and exceptional case airflow, the TL-M12Q-S fans are the better choice. However, if you need a reliable and quieter CPU cooler that fits various socket types at a lower price, the Assassin X120 SE is a solid option. Each product excels in its intended use, making your decision dependent on whether you require enhanced case cooling or focused CPU performance.
