Product information: Kama PWM 120mm Fan - 4-Pin PWMPWM (Pulse Width Modulation) is a method of slowing down the speed of a fan by switching it on and off very quickly, in contrast with the simpler method of reducing the supply voltage. The advantage of PWM is that the speed of the fan is more controllable, and power is not lost (or heat produced) through the component reducing the voltage, usually a resistor. In addition, PWM fans do not stall or fail to start at low speeds. If you decide to make use of your motherboard’s ability to control the speed of a 4-pin PWM fan, then Scythe’s PWM fans are naturally of the very best quality and offer excellent airflow and low-noise characteristics.
