Key Features
Eleven Fan Blade Design - Eleven fan blades are engineered to create large volumes of air passing through the heat sink at any angle and provides the best balance between silent and performance. Ring Silent 12 is with PWM function which allows the motherboard to run the fan precisely at its necessary speed. This guarantees the required cooling and minimizes the noise level.
Wind Blocker Frame - To achieve maximum cooling performance in all applications, the wind blocker frame is designed to direct airflow towards the middle section of the blade, thereby creating a compression effect and blocking any air from escaping. This special design reduces the blade's noise and vibration, creating a perfect balance between power and sound.
Patented Ring LED - The color and brightness uniformity of the patented LED ring is visible from all directions and adds style to the chassis. Taiwan Patent: M498806 / China Patent: CN204498539U / US Patent: 14/702,806
Hydraulic Bearing Design - The hydraulic bearing self-lubricates with a high quality, friction-reducing substance that reduces operating noise and improves efficiency. The seal cap prevents leakage of the lubricant, and improves the lifespan of the unit.
Optimized Silent Operation - For the acoustic test, Ring Silent 12 was tested in a semi-anechoic chamber which includes anti-vibration, sound-proof and sound-absorbing effect. With a LNC (Low-Noise Cable), Ring Silent 12 can reduce the noise level by 29% from 18.8 dBA to 13.4 dBA and 50% of fan speed.

Pros & Cons
👍 Pros
- Utilizes an eleven-fan-blade design to generate large volumes of airflow, ensuring effective heat dissipation.
- Offers a balanced approach between silent operation and cooling performance, minimizing noise levels during use.
- Equipped with PWM function, allowing the motherboard to precisely control fan speed based on thermal needs.
- Features a wind blocker frame that directs airflow towards the blades, optimizing compression and reducing air escape.
- Incorporates a patented Ring LED for uniform color and brightness, adding an aesthetic element visible from all angles.
- Designed with a hydraulic bearing, which self-lubricates to reduce friction, operating noise, and enhance lifespan.
- Includes a Low-Noise Cable (LNC) that can reduce noise levels by 29% and fan speed by 50% for ultra-quiet operation.
👎 Cons
- Specific RPM range for the PWM function is not provided, making it difficult to gauge its full speed customization range.
- While the Ring LED is patented, customization options for the LED color are not explicitly mentioned.
- The hydraulic bearing, while efficient, may not offer the same longevity as some advanced bearing types like magnetic levitation.
- The mention of acoustic testing in a "semi-anechoic chamber" suggests optimal conditions that may not reflect real-world user environments.
- The reduction in noise with the LNC also implies a significant reduction in fan speed, which will impact cooling performance.
