Scythe Slip Stream 140mm PWM Adjustable VR Case Fan

The Slip Stream 140 PWM Adjustable VR is a 140mm case fan with 120 mm compatible screw holes. By reducing the dimension of the center hub and enlarging the blade surface area, high airflow is generated at low RPM. The round-shaped style gives the Slip Stream 140 PWM Adjustable VR an overall compact design. It can be operated in PWM and VR mode. An additional knob allows to adjust the PWM range from a minimum of 500 to 1,200 rpm to a maximum of 650 to 1,700 rpm. By setting the switch to VR mode, PWM will be cut off, and the fan will function as a normal VR fan which can be adjusted to a fixed speed in between 500 to 1,700 rpm.

Features

• High efficiency - Compact design
  
  By reducing the dimension of the center hub and enlarging the blade surface area, high airflow is generated at low RPM. The Slip Stream 140 PWM Adjustable VR screw hole is compatible to 120 mm case fan, allowing to cool a wider area while keeping low noise and high airflow. An overall compact design is achieved by the round-shaped style.
  
  
• PWM / VR switch
  
  The Slip Stream 140 PWM Adjustable VR comes along with a PCI bracket switch allowing to choose between PWM and VR mode. By sliding the switch, the corresponding mode will be chosen. Please note: In order to take advantage of PWM function, please use the motherboard with PWM features build-in.
  
  
• Adjustable Air Flow
  
  Slip Stream 140 PWM Adjustable VR is equipped with a fan controller. By turning the knob, PWM-range or fixed speed in VR mode can be adjusted.
  Please note: PWM function will not work if the fan is connected via 4-Pin peripheral connector or connected to 3-Pin fan port. In this case, the fan will spin at the maximum speed.

The case fan comes with an adaptor for 4-Pin Molex connector.
