Fan 3 Pin 4 Pin Difference

You can also use psu to connect the fans.

Fan 3 pin 4 pin difference.

You can use a 4 pin fan power splitter. 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. 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. It will also have three square holes on the front and three wires entering the back.

A 4 pin pwm fan connector will have four square holes on the front and four wires entering the back. A 3 pin fan connector will be smaller in size than the 4 pin pwm fan connector. 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. Changes can easily cause the fan to stall or modulate erratically if the voltage isn t correct.

Same for the 4 pin fans. Like coboc lp43tx4 12 molex lp4 to 3 x 4 pin tx4 pwm fan power splitter adapter.
