Introduction to CPU Cooling
When it comes to maintaining optimal temperatures within your computer, the right cooling solution is essential. In this article, we will compare two offerings from Thermalright: the Thermalright Assassin X120 Refined SE CPU Air Cooler and the Thermalright TL-C12C X3 CPU Fan. Both products are designed to enhance cooling performance, but they cater to different needs and preferences.
Overview of Thermalright Assassin X120 Refined SE
The Thermalright Assassin X120 Refined SE CPU Air Cooler is a robust option for those looking for a reliable CPU cooling solution. Priced at $17.90, it features four heat pipes and a TL-C12C PWM fan, which works efficiently to keep CPU temperatures in check. Notably, its design includes AGHP technology that helps mitigate the inverse gravity effect, making it suitable for various orientations.
With dimensions of 125mm x 71mm x 148mm and a weight of 0.645kg, this cooler is compact enough to fit in medium-sized cases. Its aluminium heatsink cover provides durability while ensuring effective heat dissipation. Designed for compatibility with multiple Intel and AMD sockets, it includes necessary mounting hardware, making it a versatile choice for many users.
Overview of Thermalright TL-C12C X3
The Thermalright TL-C12C X3 CPU Fan, priced at $11.99, is an effective and silent cooling solution ideal for both case and CPU cooler applications. This fan operates at a maximum speed of 1550 RPM and boasts an airflow of 66.17 CFM, which is on par with the Assassin X120's fan. The TL-C12C X3 is designed with S-FDB bearings, which contribute to quieter operation and longevity, addressing common issues with fan blade vibration.
Measuring 120mm x 120mm x 25mm, this fan is compact and designed for easy installation. It includes features such as soft silicone pads to reduce noise and vibration, enhancing user experience. The TL-C12C X3 is not only suitable for use in cases but also complements CPU coolers, making it a multifunctional option for cooling enthusiasts.
Performance Comparison
When it comes to performance, the Thermalright Assassin X120 Refined SE stands out with its advanced cooling technology. The 4 heat pipes and AGHP technique allow for efficient heat transfer, which is critical for maintaining lower CPU temperatures during intensive tasks. While the TL-C12C X3 also provides effective cooling, its performance is closely tied to its application—whether as a standalone case fan or an addition to a cooler.
The TL-C12C X3's maximum speed and airflow match that of the Assassin X120's fan, providing a similar cooling capability. However, the Assassin X120's integrated design allows for a more comprehensive cooling solution directly targeting the CPU. This makes the Assassin X120 a better choice for users seeking to maximize CPU cooling efficiency.
Noise Levels
Noise levels are a significant consideration when choosing a cooling solution. The Thermalright Assassin X120 Refined SE operates at a noise level of ≤25.6 dB(A), while the TL-C12C X3 also maintains a similar noise level of 25.6 dBA. This means both options are designed to operate quietly, making them suitable for users who prioritize a low-noise environment.
Despite the comparable noise levels, the TL-C12C X3 employs vibration-reducing silicone pads to further minimize operational noise, which can be beneficial in case setups where multiple fans may generate cumulative sound. For users sensitive to noise, the TL-C12C X3 might offer a slight edge due to these additional features.
Installation and Compatibility
In terms of installation, the Thermalright Assassin X120 Refined SE comes with metal fasteners compatible with various Intel (LGA 1150, 1151, 1155, 1200, 1700) and AMD (AM4, AM5) sockets. This ensures a straightforward installation process for most users. The cooler's size makes it suitable for medium cases, which is a practical consideration for many builders.
On the other hand, the TL-C12C X3 is designed for easy installation in cases and can also be used as a supplementary fan for CPU coolers. Its 4-pin PWM connector allows for automatic speed control based on the motherboard's temperature, making it a flexible option for different cooling setups.
Price Comparison
The price difference between the two products is notable. The Thermalright Assassin X120 Refined SE is currently priced at $17.90, while the TL-C12C X3 is available for $11.99. This means that the TL-C12C X3 is about 33% cheaper than the Assassin X120. However, the higher price of the Assassin X120 reflects its more comprehensive cooling capabilities and integrated design.
For budget-conscious consumers, the TL-C12C X3 offers a significant savings opportunity, especially for those who may not require an advanced CPU cooler. Conversely, users looking for maximum cooling performance may find the investment in the Assassin X120 worthwhile.
Which should you buy?
Choosing between the Thermalright Assassin X120 Refined SE and the TL-C12C X3 ultimately depends on your specific cooling needs. If you are looking for a dedicated CPU cooler that provides comprehensive cooling performance with advanced technology, the Assassin X120 is the better choice. However, if you're in need of a versatile fan that excels in both case and cooler applications while being more budget-friendly, the TL-C12C X3 is an excellent option.
In summary, each product serves distinct purposes within the realm of CPU cooling. Consider your requirements and preferences carefully to make the best decision for your setup.
