The PWM function is an intelligent function of the cooling fan. Many electronic and electrical products hope that the cooling fan can have a speed control function. The PWM function is an intelligent speed control function, which can effectively improve the service life of the cooling fan and use the frequency of use. Based on the duty cycle, the speed of the cooling fan is automatically adjusted. When it is detected that the frequency of use is high, the cooling fan will automatically increase the speed to keep the product working at a safe temperature, and vice versa. The cooling fan with PWM function is generally 4 The black is the negative pole, the red is the positive pole, the yellow wire is the FG signal, the blue wire is the PWM wire, and some are three wires. The yellow FG signal wire is omitted. The PWM function can be used when the product does not need high-speed rotation. , Low speed work, effectively improve the life of the cooling fan, and also reduce the noise emitted by the cooling fan.
