Cpu cooling fan 3 pin vs 4 pin.
I finally replaced my cpu fan from a 3 pin to a 4 pin connector to hear the difference in sound.
You use 3 pin fans for case fans.
They use variable voltage speed control.
If your motherboard has a 4 pin header for the cpu fan i d look for a 4 pin fan for the best control.
I wouldn t be surprised if everything moved to 4 pin eventually but we re still in the early stages.
A lot of motherboards have one 4 pin header for the cpu and 3 pin headers for any other fans.
Any option can be made to work though.
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.
The 3 connector fan is very common use in laptop it can adjust the fan speed according to the cpu.
