Super silent 14cm fan with S-FLOW blades supplying 30% more airflow than a standard fan at the same speed. The greater performance combined with PWM automatic speed control allows the fan noise to be kept to a minimum.The Apache fan creates more focused airflow providing blind-spot cooling, which makes it an ideal solution for a case or heatsink fan. HDB (Hydro Dynamic) bearings extend fan life and further enhance noise reduction.Its powerful and quiet!Features:- Super silent APACHE BLACK 14cm fan- S-FLOW fan blade design delivers 30% higher airflow- Super silent with PWM speed control- Hydro Dynamic Bearing extends fan life- Application: PC case or heatsink fanSpecification:- Dimension: 140 X 140 X 25mm- Fan speed: 600 -1300 RPM- Max airflow: 89.55 CFM- Max static air pressure: 2.76 mm H2O- Noise level: 12.5 -22.19 dB(A)- Voltage rating: 12V DC- Bearing: HDB (Hydro Dynamic Bearing)- Fan life expectancy: 50,000 hours- Connector: 4pin PWM- Product code: AK-FN062
