Fan 3 Pin 4 Pin Difference

A 3 pin fan connector will be smaller in size than the 4 pin pwm fan connector.

Fan 3 pin 4 pin difference.

A 4 pin pwm fan connector will have four square holes on the front and four wires entering the back. 3 pin fans or dc fans are typically worse than 4 pin fans when changes are made to the voltage in order to adjust the speed of the fan. 3 pins 1 masse 2 12v 3 compte tour retour du ventilo 4 pins 1 2 et 3 idem 3pins 4 pwm ça c est la théorie passons à la pratique un 3pins peut réguler sa vitesse en analogique sur le 12v c est à dire qu il fait varier la tension. 4 pin fans or pwm fans don t have this issue as the 4th pin on the fan allows voltage changes to be made more quickly and less erratically.

Hey guys on todays episode we learn about the difference between 3 pin and 4 pin fans and whether one or the other performs better for cpu cooling. Three wire and four wire fan connectors. Changes can easily cause the fan to stall or modulate erratically if the voltage isn t correct. You can also use psu to connect the fans.

Same for the 4 pin fans. You will need a 4 pin tx4 pwm fan power splitter adapter. Like coboc tx4spl3 6 3 x 4 pin tx4 pwm multi fan power splitter cable. A four pin connector is a little different than the three pin connector since it has the extra fourth wire used for controlling and sending signals to the fan which likely has a chip on it that tells it to slow down or speed up in addition to the other wires the three pin connector has.
