Product Introduction

CPU fan 4Pin interface, the motherboard can control the 12V fan power supply through this extra pin, so as to achieve the purpose of controlling the fan speed. RPM dual intelligent fan (temperature control + PWM), that is, the 4PIN plug has no PWM function. If the 4PIN fan is plugged into the 3PIN motherboard, it can only run at the lowest speed by default. Connect a 5V voltage to the fourth line That's it. Or short-circuit the 12V connector in the 4PIN socket with the PWM signal line (PWM is usually the fourth blue line) to make the fan work at full speed. The 3PIN fan can be used directly on the motherboard 4PIN socket, but the original fan speed control function of the motherboard is gone. If the motherboard supports BIOS speed control, set it to DC. Some motherboards may prompt that the CPU fan is not plugged in every time it is turned on. You need to enter the BIOS to turn off the "Fan Monitoring" option.
