Thermalright TL-M12-S Infinity Mirror aRGB Lighting Black Fan 120mm

Thermalright TL-M12-S is a 120 mm case fan aimed at people who want decent airflow, low noise, and aRGB aesthetics without compromising functionality. The black design with Infinity Mirror ARGB Lighting looks good in dark builds and showcases with a transparent panel. The range of 500–1500 RPM gives you freedom – from almost silent operation to stable cooling under higher loads. At maximum up to 23.2 dBA, the fan is oriented towards a quieter system.

What you get

With a size of 124 x 120 x 25 mm, the fan fits into standard 120 mm positions in the case – front, top, rear exhaust, depending on where you need airflow. The maximum airflow of 47.6 CFM is sufficient for normal gaming and workstations, especially in combination with several such fans for better overall pressure. The static pressure of 1.31 mmH2O makes it adequate not only for fully open mesh panels but also for cases with filters and denser front meshes. S-FDB Bearing and Magnetic Bearing Optimized design help for smoother rotation and lower noise during long operation. Thanks to PWM control and “PWM and ARGB Sharing Design,” you can easily synchronize speeds and lighting with the motherboard and keep the system quiet at idle, while more aggressive under load.

• Standard size for case 120 mm with actual dimensions 124 x 120 x 25 mm, making it compatible with most ATX and mATX cases.
• Speed range 500–1500 RPM, allowing a balance between silence at low speeds and more serious cooling under load.
• Airflow up to 47.6 CFM, suitable for general case ventilation and maintaining lower temperatures for CPU and GPU.
• Static pressure 1.31 mmH2O, which helps air pass more effectively through dust filters and denser panels.
• Low noise level up to 23.2 dBA, combined with S-FDB Bearing and Magnetic Bearing Optimized for better acoustic performance.
• 4 PIN PWM connector for speed control from the motherboard and 3 pin ADD-RGB 5V (V-D-NC-G) for synchronization of Addressable RGB lighting.
• Infinity Mirror ARGB Lighting and black color for a more striking appearance in glass or open cases, plus 24 months warranty from the manufacturer.

Who it is suitable for

TL-M12-S is a good choice if you are building a gaming or work system and looking for a balance between aesthetics and functional cooling of the case. It is suitable for builds with a 5V aRGB ecosystem, where you want synchronized lighting and relatively quiet operation. If you are aiming for extreme airflow or have a very limited case needing maximum pressure, you will likely need to combine several such fans or look for more specialized solutions.

The most sensible aspect here is the combination of PWM control, decent airflow, and Infinity Mirror ARGB in a compact 120 mm format. You get a fan that adequately cools while contributing to a finished look of the build.
