4 Wire PC CPU Fans Temperature Board Speed Controller Governor, DC 12V 3A PWM Fan Speed Controller Module, Speed Regulation Control On Off Switch for PC CPU Case Chassis Cooling Fan

About this item

✅【Manual or Automatic】--This PC fan temperature controller has two modes: Manual speed control and automatic temperature control. In addition, the thermostat also supports inverse fan timing control to help you flexibly manage the fan running time and achieve personalized and refined heat dissipation control. | ✅【Reverse Sequence Mode】--This DC 12V PWM fan speed controller module is used in most reverse timing four wire fan control. When fan is in normal mode control, speed change is opposite, and control line is connected to negative pole at full speed. | ✅【PWM Control Mode】--This temp controller has conventional pwm fan control mode (default mode). This mode is used for the four wire fan control. PWM output range of temperature controller is 10% -100, working temperature is -10℃ to 60℃, use this programmable thermostat for greenhouse exhaust fan, attic fan and other exhaust cooling fan system maximize. | ✅【Reverse Sequence Fan 80% Control】--This PC fan speed regulation reverse sequence fan 80% control mode is used in a very rare type of reverse timing fan, when the fan is in conventional mode control, the speed change is opposite, and the control line is not turned when the negative electrode is connected. | ✅【Reverse Timing Fan】--This PWM fan controller can control the fan effectively. In normal mode, the change of fan speed is opposite to that of normal mode. When the control line is connected to the negative electrode at full speed, a specific control effect can be achieved and a variety of fan operation state adjustment can be achieved.
