Riing Silent 12 Pro Blue CPU Cooler

The Thermaltake's latest Riing Silent 12 Pro CPU cooler sets itself apart from the rest with its superb cooling performance, ultra-quiet operation and aesthetic design.

The Riing Silent 12 Pro has optimized 0.5mm thickness aluminum fins and five direct contact heatpipes, delivering rapid, highly effective heat dissipation. Thanks to the included 120mm fan which features up to eleven fan blades, wind blocker frame, PWM function, hydraulic bearing design, etc., more airflow will be created to cool the heatsink without producing more noise. A Low-Noise cable is also included for optimized silent operation.

Add a stylish touch to your chassis. Thermaltake's exclusive LED ring (available in Blue and Red colors) maintains color and brightness uniformity. Especially, the lighting effect is visible from all sides and angles.

With non-interference cooling design, the Riing Silent 12 Pro CPU cooler achieves the best RAM clearance, allowing you to easily install high-end overclock RAM beside it. The included special-designed fan clips make assembly and disassembly a breeze.

Unique Riing LED

The color and brightness uniformity of the unique LED ring is visible from all directions and adds style to the chassis.

general information

Superior Heat Dissipation

Optimized 0.5mm thickness aluminum fins with 2.7mm air gap, and 5 x ⌀ 6mm solid copper heat-pipes are designed for rapid heat dissipation, allowing maximum heat conductivity. The tower’s side flow design delivers the best cooling performance. In addition, the heat-pipes are in continuous direct contact with the CPU to ensure fast and efficient heat dissipation.

Thermal Image Demonstrates for Heat Distribution

The Riing Silent 12 Pro series delivers outstanding cooling performance, keeping the temperature between 24°C and 29.4°C (ambient temperature is 21°C) @Intel Core i7-4770K 3.8Ghz at full Load.

general information

Eleven Fan Blade Design

The Riing Silent 12 Pro is outfitted with a 120mm fan for maximum airflow performance. Eleven fan blades are engineered to generate large volume of air passing through the heatsink at any angle and make a perfect balance between silence and performance.

The fan is with PWM function which allows the motherboard to run the fan precisely at its necessary speed. This guarantees the required cooling performance as well as minimizes the noise level.

general information

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.

general information

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.

general information

Optimized Silent Operation

For acoustic test, the Riing Silent 12 Pro series was tested in a semi-anechoic chamber which includes anti-vibration, sound-proof, and sound-absorbing effect.

With a LNC (Low-Noise Cable), the Riing Silent 12 Pro series can reduce 37% of noise level from 21.7dBA to 13.5 dBA, and 50% of fan speed.
