Scthye Slip Stream 120 PWM Adjustable

The Slip Stream Adjustable PWM fan is the third new version of the PWM Slip Stream series. As needed, users can adjust the PWM bandwidth manually to control the fan speed by sliding the switch on a PCI bracket, so the fan is optimized for quiet operation or highest performance. PWM function is still maintained as the general feature. Speed of this fan variation is continuously adjustable between 470 ( 30%) to 1,340 rpm ( 10%) and 740 ( 25%) to 1,900 rpm ( 10%).
