Overview of the Products
The Thermalright TL-C12CW-S X3 CPU Fan is priced at C$17.99, making it an affordable choice for users seeking an efficient cooling solution. In contrast, the Thermalright Assassin X 120 SE CPU Air Cooler is more expensive at C$25.59, but it offers additional features tailored for CPU cooling. Both products are designed by Thermalright, a brand known for its commitment to quality in computer accessories.
The TL-C12CW-S X3 is primarily a case cooler with a focus on aesthetics through its ARGB lighting, while the Assassin X 120 SE serves as a dedicated CPU cooler with advanced engineering features. Understanding their specifications and functionalities will help potential buyers make informed decisions.
Cooling Performance
Cooling performance is a crucial factor in selecting a CPU cooler or fan. The TL-C12CW-S X3 boasts a maximum speed of 1550 RPM and an airflow rating of 66.17 CFM, which ensures effective cooling for various applications. Its design incorporates quality S-FDB bearings that reduce noise levels to a maximum of 25.6 dBA, providing a quieter operation.
On the other hand, the Assassin X 120 SE also features a fan speed of 1550 RPM and achieves the same airflow of 66.17 CFM. However, it is equipped with four 6mm heat pipes that apply the AGHP technique, allowing it to handle a Thermal Design Power (TDP) of 125 to 225 watts. This makes it suitable for more demanding CPU cooling tasks, providing a significant advantage for high-performance builds.
Build Quality and Design
When it comes to build quality, both fans showcase Thermalright's commitment to durability. The TL-C12CW-S X3 has been designed with high-brightness LED atomizing ARGB fan blades, contributing not only to its cooling capabilities but also to its visual appeal. It measures 120 x 120 x 25 mm and is designed for easy installation in cases and CPU coolers.
Conversely, the Assassin X 120 SE features a sturdier construction with a weight of 0.645 kg, and its dimensions are 125 x 71 x 148 mm. This air cooler is built using industrial-grade materials that ensure longevity and reliability. Its design accommodates a variety of CPU sockets, including Intel and AMD, enhancing its versatility in different setups.
Noise Levels
Noise levels can significantly impact user experience, especially in a quiet environment. The TL-C12CW-S X3 operates at a noise level of 25.6 dBA, making it an excellent choice for those who prioritize a silent computing experience. Its automatic speed control through the 4PIN PWM fan cable interface further optimizes its operation based on motherboard temperature.
The Assassin X 120 SE shares the same noise level of 25.6 dBA, thus ensuring a quiet operation as well. However, its dual functionality as a CPU cooler means it may be subject to more demanding thermal conditions, potentially leading to higher noise levels under load. Nevertheless, both models provide a balanced approach to performance and noise management.
Lighting Features
Aesthetics play a role in many PC builds, especially for users who appreciate RGB lighting. The TL-C12CW-S X3 shines in this aspect, featuring up to 17 modes of light effects with ARGB support. This allows for synchronization with other components via the motherboard, creating a visually stunning setup.
In contrast, the Assassin X 120 SE lacks the same level of RGB lighting features. While it does not focus on lighting aesthetics, its design emphasizes functional cooling performance. Users who prioritize visual appeal may find the TL-C12CW-S X3 more attractive, while those who favour functionality may lean towards the Assassin X 120 SE.
Installation Process
Ease of installation is an important consideration for many users. The TL-C12CW-S X3 is designed for straightforward installation, making it suitable for both novice builders and seasoned enthusiasts. Its compatibility with various case setups means users can easily integrate it into their existing systems.
On the other hand, the Assassin X 120 SE comes with metal fasteners that facilitate installation on both Intel and AMD platforms. The inclusion of different mounting plates ensures a secure fit regardless of the CPU socket type. Although installation may require a bit more effort due to its larger size, the added compatibility makes it a worthwhile option for serious builders.
Price Comparison
In terms of price, the TL-C12CW-S X3 is more budget-friendly at C$17.99, making it an attractive choice for users looking for an effective case cooling solution without breaking the bank. Its features provide good value for those seeking essential cooling capabilities.
Conversely, the Assassin X 120 SE is priced at C$25.59, which reflects its advanced cooling technology and versatility. While it may be pricier, its enhanced performance for CPU cooling can justify the cost for users who require more robust thermal management for high-performance builds.
Which should you buy?
Choosing between the Thermalright TL-C12CW-S X3 CPU Fan and the Thermalright Assassin X 120 SE CPU Air Cooler ultimately depends on your specific needs. If you are looking for an affordable, visually appealing case fan with decent cooling performance, the TL-C12CW-S X3 is a suitable option. However, if you require a more powerful cooling solution with better compatibility for various CPU sockets and enhanced thermal management, the Assassin X 120 SE is worth the investment. Assess your cooling requirements and budget to make the best decision for your build.
