Cpu Cooling Fan 3 Pin Vs 4 Pin
You use 3 pin fans for case fans.
Cpu cooling fan 3 pin vs 4 pin. 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. A lot of motherboards have one 4 pin header for the cpu and 3 pin headers for any other fans. Now 2 pin cooling fans have been less to use because the fan of 2 pin cannot meet the requirements in terms of shifting etc in contrast 3 pin 4 pin fan is the main stream now. If your motherboard has a 4 pin header for the cpu fan i d look for a 4 pin fan for the best control.
2 advantages to 3 pin vs 4 pin fans 3 pin computer fan. Any option can be made to work though. They use variable voltage speed control. For custom cooling usually the pump is contrlled by the motherboard cpu fan header 4 pin and the radiator fans are controlled either by the case fan 3 pin motherboard headers or by a module eg corsair h100i.
I finally replaced my cpu fan from a 3 pin to a 4 pin connector to hear the difference in sound.
