Lnfxkvva 3X PWM Speed Controller 4Pin PWM Fan Governor USB TYPE-C Power Supply DIY Watercooling Cooler

This governor is recommended to control the output power within 7-8 watts (12V 0.6A) This governor input port is USB Type-c female. Built-in DCDC boost circuit(boost USB 5V to 12V). Built-in pwm signal generator ( to adjust speed) Output is standard PWM 4pin fan port, Fan speed adjustment range 0-100%, Turn the knob clockwise to increase the speed, Turn the knob counterclockwise to reduce the speed, Turn counterclockwise to close the output. Features: This PWM Speed controller support 12v standard fan speed control, also support computer water cooling PWM pump speed adjustment. The application scenario of the governor design is mainly powered by the charging /rechargeable battery, the common output capacity is generally 5V/2A, higher specifications are relatively rare, and the parameters of 12v/0.7A fan almost reach 5V/2A full power supply, while taking into account the small size of the PWM governor so limited cooling capacity.
