4pin Cooling Fan Speed Controller, PC Computer Case PWM Fan Controller, According to The Measured Temperature Control Product Description 4pin Fan Controller, can only be used for 4-wire KF2510 fans with PWM function. The package includes 1 fan speed regulator and 2 B3950 temperature sensors. PWM fan controller, Temperature Control fan speed. used for PC case computer fan
Acceleration temperature "L * *": can be set within the range of 5-94, when the temperature rises and exceeds this temperature, the PWM output begins to follow Raise as the temperature rises.
Full speed temperature "H * *": can be set within the range (10-99), PWM always outputs when the temperature rises or exceeds this temperature, the fan is running at full speed.
Turn off temperature "C * *": can be set within the range (0-92), low-temperature shutdown temperature. When this value is set to>0, the low-temperature shutdown function is enabled. When the temperature is below this temperature, the fan output is turned off (both the fan power supply and PWM signal are turned off). When the temperature rises above the acceleration temperature, the fan restarts and changes speed according to the temperature; If the shutdown temperature is set to 0, the low-temperature shutdown function will be disabled, and the PWM and fan power will always be output.
Note: The difference between the acceleration temperature and the full speed temperature must not be less than 5°C, and the difference between the turn off temperature and the acceleration temperature must not be less than 2°C. When modifying parameters, if the values are lower than the above temperature difference values, the program will automatically adjust the other parameters.
