г Evre Meslek Tutuklamak 4 Wire Fan Pinout Davacд Circulo Pin 2 (vcc): connect the red wire from the fan. pin 3 (sense): connect the yellow wire from the fan (optional). pin 4 (control): connect the blue wire from the fan (optional). wiring a computer fan with a 4 pin connector is a straightforward process once you understand the purpose of each pin. It provides the necessary power and control signals to the fan. the fan header usually has four pins to accommodate the 4 wire fan. 2. power pins: the power pins on the fan header provide the necessary electrical power to the fan. in a 4 wire computer fan, there are two power pins labeled as vcc (voltage common collector) and gnd (ground).

Wiring a 4 pin fan direct to 12v dc. The 4 wire setup includes power, ground, tachometer, and pulse width modulation (pwm) wires. the power wire of the 4 wire fan connects to the 12v power supply of your computer, providing the necessary energy for the fan to operate. the ground wire, on the other hand, completes the electrical circuit, ensuring proper functioning.

Ok now, a number of points here. a 4 wire fan is not controlled by a transistor, you feed pwm directly to the control wire while the fan remains connected to 12 v and ground. you use the "tacho" wire as an input to the arduino to monitor the fan speed. i seem to recall it is an open collector so you would use input pullup on that pin.
