Working Current:0.8A
Temperature Sensor Probe: 50K 3950
Speed Output Control Range:5%-100%
Module Size:43X18X9mm/1.69X0.71X0.35inch(L*W*H)

Package Included:
1X 4 Wire PWM Case Fan Thermostat Speed Controller
1X Temperature Sensor Probe

Working Mode Setting Instructions
Manual Mode:do not install the temperature sensor,then single press (increase)/double press(decrease) the button to change the fan speed(after change the speed and wait 20s, it will save the setting automatically,during this process,the 2th indicator will flash,when the speed can not increase or decrease, the 3 and 1 indicator will flash)
Auto temperature control mode:install the temperature sensor,the manual set speed as the intial speed,when the temperature reach the speed-up temperature(Tu),the fan will speed up,when the temprature reach the full speed temperature, the fan will rotate in full speed.(the setting instructions please refer to the picture)
Fan Shutdown Mode:support non shutdown working mode(1);2 degree lower than than speed up temperature(Tu) will shutdown(2);5 degree lower than than speed up temperature(Tu) will shutdown(3). power off the module, then press the button but do not release and power on the module until 3 indicators flash at the same time to enter the mode setting, press the button to change the mode,after setting, long press the button to save the working mode.

Product review & video

[Applause] [Music] [Applause] hey guys in this video I'm going to be showing you how to control 12 volt CPU fans using an Arduino here's a sneak peak of my Arduino controlled hovercraft at this point this is just a very crude prototype but I do plan on making two different versions of this hovercraft using the fan control technique shown in this video the fans I'll be using in this video are all 12-volt DC but I am planning on automating this 120 volt attic fan in a future video now each of these fans has a 12 volt brushless motor so why does this fan have two wires this band have three wires and this fan have four wires well with each additional wire we get a little more capability let's start with the two wire the two wire fan just has a red and black wire the red obviously for positive and the black for negative because it is a 12-volt fan we're going to need a transistor or MOSFET t
