Introduction to CPU Cooling Solutions
When selecting a CPU cooling solution, finding the right balance of performance, noise level, and aesthetics is crucial. In this comparison, we will look at two offerings from Thermalright: the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright TL-C12CW-S X3 CPU Fan. The former is priced at C$24.29, while the latter is available for C$17.99. Both products are designed to enhance cooling efficiency but cater to different needs within the realm of CPU cooling.
Performance Comparison
In terms of cooling performance, the Thermalright Assassin X 120 SE ARGB CPU Air Cooler is built to handle a thermal design power (TDP) ranging from 125 to 225W, making it suitable for high-performance CPUs. It features four 6mm heat pipes that utilise Advanced Gravity Heat Pipe (AGHP) technology, which helps mitigate the inverse gravity effect for improved heat dissipation. On the other hand, the Thermalright TL-C12CW-S X3 CPU Fan operates at a maximum speed of 1550 RPM and can move air at a rate of 66.17 CFM. While the fan is effective, it primarily serves as a supplementary cooling component rather than a primary CPU cooler.
Noise Levels
Noise is an important consideration for many users, especially those who build quiet PC systems. Both products maintain low noise levels, with the Assassin X 120 SE boasting a noise level of ≤25.6 dB(A). The TL-C12CW-S X3 matches this with a similar maximum noise level of ≤25.6 dBA. This means that both cooling solutions are designed to operate quietly, allowing for a more serene computing environment, regardless of which option is ultimately chosen.
Aesthetic Appeal
Aesthetics can significantly influence purchasing decisions, particularly for users who appreciate a visually appealing setup. The Thermalright Assassin X 120 SE features ARGB lighting, which provides a modern touch to the cooler, enhancing the overall look of your build. The TL-C12CW-S X3 also boasts high-brightness LED atomizing ARGB fan blades, capable of displaying up to 17 different lighting modes. This makes it an excellent choice for those who want to synchronise their cooling components with the rest of their RGB setup.
Compatibility and Installation
Compatibility is a key factor in ensuring that your cooling solution fits your system. The Thermalright Assassin X 120 SE is designed to support a variety of CPU sockets including Intel’s 115X, 1200, 1700, and AMD’s AM4. It comes with the necessary mounting plates and fasteners for easy installation. In comparison, while the TL-C12CW-S X3 is primarily a case fan, it can also be used in conjunction with CPU coolers to enhance cooling performance. However, it does not include specific mounting solutions for CPU coolers, which could limit its versatility in certain setups.
Build Quality
Both products are constructed with quality materials, ensuring durability and longevity. The Thermalright Assassin X 120 SE features a heat sink made from aluminium, while employing S-FDB bearings to ensure a long service life of up to 20,000 hours. The TL-C12CW-S X3 also utilises S-FDB bearings, designed to reduce fan blade shaking and noise while maximising cooling performance. Both products reflect Thermalright’s commitment to quality, but the Assassin X 120 SE may offer a slight edge in terms of overall construction, given its design as a dedicated CPU cooler.
Value for Money
When it comes to pricing, the Thermalright Assassin X 120 SE is priced at C$24.29, while the Thermalright TL-C12CW-S X3 is slightly more affordable at C$17.99. The difference in price reflects the different roles each product serves; the Assassin X 120 SE is a full-fledged CPU cooler, while the TL-C12CW-S X3 is primarily a case fan that can be used to support other cooling solutions. Users looking for a dedicated CPU cooler may find the additional cost of the Assassin X 120 SE justified for its superior cooling performance.
Which should you buy?
Choosing between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright TL-C12CW-S X3 CPU Fan ultimately depends on your specific cooling needs. If you require a robust solution that can handle high-performance CPUs and offer excellent cooling efficiency, the Assassin X 120 SE is the better choice, especially given its TDP capabilities and compatibility with various CPU sockets. Conversely, if you are looking for a more budget-friendly option that enhances airflow and aesthetics within a case, the TL-C12CW-S X3 is an excellent option. Each product serves its purpose effectively, catering to different user preferences in the realm of CPU cooling.
