Both products are designed to enhance the cooling performance of your PC, but they cater to slightly different needs and preferences. Priced at £15.90 and £16.29 respectively, these coolers represent competitive options for users seeking efficient thermal management.
Performance Evaluation
When it comes to performance, both the Thermalright TL-C12C-S CPU Fan and the Assassin X120 SE boast impressive specifications. The TL-C12C-S operates at a maximum speed of 1500 RPM, delivering an air flow of 66.17 CFM while maintaining a noise level of just 25.6 dBA. In contrast, the Assassin X120 SE features a slightly higher maximum fan speed of 1550 RPM, also providing an air flow of 66.17 CFM. Both coolers promise efficient cooling with minimal noise, but the Assassin X120 SE’s fan speed advantage may offer a slight edge in cooling performance under heavy loads.
Design and Build Quality
In terms of design, the Thermalright TL-C12C-S CPU Fan presents a compact and straightforward layout, measuring 120mm x 120mm x 25mm. It integrates high-brightness ARGB lighting which can be synchronised with other components, providing a visually appealing aesthetic. The Assassin X120 SE, on the other hand, is slightly bulkier with dimensions of 120mm x 71mm x 148mm, featuring a more complex design with a heat sink and multiple heat pipes. The use of industrial-strength materials in the Assassin X120 SE enhances its durability, making it suitable for a variety of setups and ensuring longevity.
Noise Levels
Noise levels are a crucial factor for many PC builders, especially for those who prefer a quiet operating environment. Both the TL-C12C-S and the Assassin X120 SE operate at a maximum noise level of 25.6 dBA, which is commendable for cooling fans. The TL-C12C-S utilises S-FDB bearings to minimise noise and extend the fan’s lifespan, while the Assassin X120 SE also incorporates similar technology for quiet performance. Therefore, users can expect both products to operate quietly, making them ideal for gaming and multimedia setups.
Installation and Compatibility
Installation ease and compatibility are essential for a seamless building experience. The Thermalright TL-C12C-S is versatile enough to be used either as a case fan or in conjunction with a CPU cooler, making it a flexible choice for various configurations. The Assassin X120 SE is designed specifically for CPU cooling with compatibility across multiple Intel and AMD sockets, including LGA 1700 and AM5. It comes equipped with the necessary mounting hardware, ensuring a straightforward installation process. If you're looking for a dedicated CPU cooler, the Assassin X120 SE may be the better option.
Aesthetic Appeal
Aesthetic appeal is a significant consideration for many PC enthusiasts. The Thermalright TL-C12C-S boasts an attractive ARGB lighting system, providing up to 17 different lighting modes that can be easily managed and synchronised with other ARGB components. Conversely, the Assassin X120 SE also features colourful ARGB effects, enhancing its visual presence within a case. Both products offer aesthetic enhancements, but the TL-C12C-S may appeal more to those who prioritise flexible lighting options and visual flair.
Brand Reputation
Thermalright has established itself as a reputable brand in the cooling market over the past two decades, known for its commitment to quality and performance. Both products are backed by this brand reputation, ensuring that buyers can trust in their performance and build quality. The TL-C12C-S is primarily marketed as a reliable case fan that can also serve CPU cooling needs, while the Assassin X120 SE is positioned as a dedicated CPU cooler, reflecting Thermalright's focus on developing specific solutions for different cooling requirements.
Price Comparison
Price-wise, the Thermalright TL-C12C-S CPU Fan is available for £15.90, while the Thermalright Assassin X120 SE ARGB CPU Air Cooler is slightly more expensive at £16.29. The price difference of £0.39 may seem minimal, but it is important to consider what each product offers in terms of features and performance. For users who prioritise dedicated CPU cooling, the small premium for the Assassin X120 SE may be justifiable given its design and enhanced performance capabilities.
Which should you buy?
Deciding between the Thermalright TL-C12C-S CPU Fan and the Thermalright Assassin X120 SE ARGB CPU Air Cooler ultimately depends on your specific cooling needs and preferences. If you require a versatile fan that can function well in multiple roles and offers impressive aesthetics with its ARGB lighting, the TL-C12C-S is an excellent choice.
