The first wire of the white 4-pin fan connector is the ground/common (0V) lead, and the next is the power (+12V) wire. Step 4: PWM Fan Controller – PWM Control Setup. Automated Mini Fan Speed Controller (4-Pin PWM) - Support both "4-Pin Auto Speed PWM mode" and "3-Pin Manual Speed mode" FC-PWM-MINI. Joined Jan 27, 2003 Messages 998. In order to be sure of a correct fan speed reading under PWM control, it is necessary to periodically switch the fan on long enough to get a complete tach cycle. If you buy a 4-pin PC fan, the 4th pin is for PWM control. Having a complete kit available for users who don't want to source their own is a good idea. This PWM controller is cheap and easy to build, but has no temperature control and with components shown runs at relatively low frequency. This is done by injecting an extra clock pulse into the CNT6 block, causing it to output one clock cycle earlier than it … 3.1 out of 5 stars 7. The MOSFET should be able to switch 8A before it gets too hot without a heatsink. I/P Signal Voltage : 5V (PWM or Squre Wave), Use for the brightness of the LED / LED light strips. Each PC fan can be controlled separately and you’re able to select lots of different input factors for your PWM fan curves like for example the CPU temperature or the average GPU temperature make a nice curve. This is achieved with several digital logic components. PWM Fan Controller sketch can be downloaded here. PWM Fan Controller: You can see the PWM Fan Controller project here.

Its designed for PC fans which are normally 12V, the current will depend on the fan, normal PC fans usually take less than 0.5A, but I was using a server fan taking up to 3A. The resulting digital value is converted to a temperature and a fan is powered proportionally to how hot the sensor is. This device uses a built in pulse width modulated signal generator circuit for triggering a power MOSFET. Hi,I live in Brazil. As you might noticed, if no PWM signal is present, the fan will run at on 100% speed, meaning, if you want to run the fan at full speed, simply leave its PWM control input lead free (a crude method) or apply a PWM signal with 100% duty cycle (an advanced method). Think of a PWM signal as if it were a beating heart. Tachometer-output waveform in 3-wire fans—ideal, and under PWM control. Base PWM frequency is 25kHz but it’s acceptable from 21kHz to 28kHz. NA-FC1 is a flexible Noctua controller suitable for 4 pin PMW fans. Gamdias Chione M2-240R All-in-One CPU Liquid Cooler. If the fan has a PWM speed control input (typically this is a “4-wire” fan), the recommended PWM frequency is usually in the 20kHz to 30kHz range. To achieve the fan control with the voltage from the power supply, a mosfet is used to handle the switching of the power supply on and off with pulse-width-modulation (PWM). and my personal site here: Feature:Support all within 12V 5A fans, synchronous rectifier output, high efficiency!

It varies the speed of the fan with temperature. After that Take print out of PCB Layout on glossy paper. The speed is controlled through an externally applied varying DC voltage source. You can use this PWM controller as LED driver. In the final step, a PWM pulse is given to the TRIAC as per the speed requirements, which in turn varies the ON/OFF timing of the AC signal and provides a variable output to control the Fan speed. The output of the LM35 is connected to an ADC (analog to digital converter) so that we can get a usable reading from it, but first we need to do a small calculation. It can work in two different modes – automatic, i.e. This circuit is designed as per a request made by Mr Vinoth from India. I/O Pin 9 on the Arduino board is directly connected to fan control input and by reading the state of 3 push buttons on pins 2,3,4 different PWM values are sent to the fan. Share it with us!
