user can switch the mode between PWM & V.R. (Variable Regulation – To manually control the fan speed) by sliding the switch on PCI bracket.
This switch can be attached into any empty PCI Slot.
Small Center Hub & Wide Blade Type:
By reducing the dimension of the center hub and enlarging the blade surface area, high airflow is generated at a low RPM.
In Order to take advantage of PWM function, please use the motherboard with PWM features build-in.
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.
Connection to any third arty market fan controller with 3-Pin port, PWM function will not work but fan speed can be adjusted by the fan controller.
