Be Quiet! Silent Wings 3 140Mm Pwm High-Speed Case Fan

Description :

• Mfr Part Number: BL071
• Features:
  • Great performance-to-noise ratio with 28.1dB(A) at 1,600rpm
  • 6-pole fan motor with three phases giving very low power consumption and less vibration
  • Advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours
  • Seven fan blades with optimized surface structures ensure excellent airflow
  • The rubberized fan frame is equipped with funnel-shaped air inlets producing extremely high air pressure
  • Removable anti-vibration mountings minimize the transmission of vibrations to the PC case and its components
  • Advanced high quality IC motor controller reduces electrical noise
  • Pulse width modulation (PWM) allows compatible 4-pin controllers (including those built into many motherboards) to intelligently vary the speed of the fan
  • With PWM your system can ramp up the cooling when it's needed, or operate in maximum quiet mode when it's not
