Overview of Thermalright Products
The Thermalright TL-S12W X3 CPU Fan and the Thermalright Assassin X 120R SE Plus CPU Cooler are both strong contenders in the CPU cooling market. The TL-S12W X3 is priced at C$19.59, while the Assassin X 120R SE Plus comes in at C$25.59. Both products reflect Thermalright's dedication to quality, with over 20 years of experience in developing cooling solutions. Despite their shared brand lineage, each product serves a distinct purpose in the realm of CPU cooling.
Design and Build Quality
When it comes to design and build quality, the Thermalright Assassin X 120R SE Plus CPU Cooler stands out with its 4×6mm heat pipes and advanced AGHP technique, which mitigates the inverse gravity effect. This cooler is made from industrial-grade PBT + PC material, ensuring durability and longevity. On the other hand, the TL-S12W X3 CPU Fan is constructed using insulation-grade PBT+PC and features soft silicone feet to dampen noise. While both products exhibit robust construction, the Assassin X 120R SE Plus offers enhanced durability and advanced technology for more demanding cooling requirements.
Cooling Performance
In terms of cooling performance, the Thermalright Assassin X 120R SE Plus outshines the TL-S12W X3. The Assassin X 120R SE Plus features two PWM fans, achieving airflows of 66.17 CFM and 58 CFM at maximum speeds of 1550 RPM and 1500 RPM, respectively. In contrast, the TL-S12W X3 provides a maximum airflow of 47.6 CFM at 1500 RPM. The higher airflow of the Assassin X 120R SE Plus makes it better suited for cooling CPUs that generate significant heat, giving it an edge in performance.
Noise Levels
Noise levels are crucial for users seeking a quiet computing experience. The TL-S12W X3 operates at a maximum noise level of 23.2 dBA, making it a relatively quiet option. Meanwhile, the Assassin X 120R SE Plus has a slightly higher noise level, reaching up to 25.6 dBA. While both products maintain relatively low noise levels, the TL-S12W X3 is the quieter option, appealing to those who prioritise a silent operation.
Installation and Compatibility
The installation process and compatibility options differ between the two products. The TL-S12W X3 comes in a package that includes three fans, 12 mounting screws, and an instruction manual, providing everything needed for installation.
