be quiet! Silent Wings 3 120mm PWM 1450 RPM Computer PC 4 PIN Cooling Case Fan

Description

This is a be quiet! Silent Wings 3 120mm PMW Case Fan.  Part # BL066.
Virtually silent, extraordinary cooling
be quiet! SilentWings® fans are known for their cutting-edge technology, virtually silent operation, and extraordinary cooling power. The third generation of this multiple-award-winning fan series offers unparalleled and uncompromising performance with many intelligent optimizations: a high-quality 6-pole motor, a durable fluid dynamic bearing, unique airflow-optimized fan blades, as well as a rubberized fan frame with funnel-shaped air intakes.
The SilentWings® 3 120mm PWM model achieves the perfect balance between silence and performance with a maximum volume of 15.5dB(A), and it meets every requirement to make it the perfect choice for installation on heatsinks and radiators, as well as in PC cases.
Performance Features
Virtually Silent Operation
Virtually silent operation at max. 16.4dB(A)
6-pole motor with three phases for very low power consumption and quiet, nearly vibration-free operation
Cutting-edge fluid dynamic bearing ensures a lifespan of up to 300,000 hours
Seven fan blades with optimized surface structure ensure excellent airflow
The rubberized fan frame is equipped with funnel-shaped air intakes for extremely high air pressure
Removable anti-vibration attachments minimize vibrations transferred to the PC case and surrounding components
High-quality IC motor control reduces electronic sounds
Additional PWM Functionality
Using Pulse Width Modulation (PWM), the fan speed can be intelligently controlled with 4-pin fan controllers (including those installed on many motherboards)
With the PWM, the system can ramp up the cooling as needed or run with maximum quietness during low-usage times
Product Conception, Design, and Quality Control in Germany
Especially well-suited for use in high-performance water- and air-cooling systems
