Connecting the fan to the arduino. we can connect up to 3 pwm fans to a single arduino. this is the pinout of a standard pwm fan: black: ground. yellow: 5v, 12v or 24v (depends on fan model, usually 12v for desktops, 5v for laptops) green: sense. used to measure rpm. The fans used in a computer either as case fans or cpu fans need a 12 volt dc power supply and are controlled by a 25 khz pwm signal. the reason for a 25 khz signal is to eliminate, or at least reduce, the pwm noise and just leave the noise of the wind and the bearings, since this frecuency is outside of the human hearing range (20 hz 20 khz). In case anyone's interested, here's the code adjustment for pot controlling the fan: int potval; int potpin = a2; int fanval; const byte oc1a pin = 9; const byte oc1b pin = 10; const word pwm freq hz = 25000; adjust this value to adjust the frequency const word tcnt1 top = 16000000 (2 * pwm freq hz); void setpwmduty (byte duty) { ocr1a.

Create a non blocking rpm measurement (with millis ()) this post addresses all three issues regarding how to pwm a 3 pin pc fan with an arduino. 1. you need a pnp transistor. most tutorials show an npn transistor driving a motor as a low side switch. however, the problem with this approach is that you are switching the ground (gnd) path. Luckily all of my noctua fans responded to this signal, though i can’t promise other fans will. set timer 1 divisor to 1 for pwm frequency of 31372.55 hz. tccr1b = tccr1b & b11111000 | b00000001; so with a single line added to our setup () we’ve got pins 9 & 10 able to control our fans. hook up the 12v and ground, and you’re good to go.
